The o-rings hold the telfon ring in place, You put the teflon ring in with a little grease, put the o-ring around the teflon ring and in the Freezer for an hour or so
Hi Gary, thank you for the response on the o-rings. The issue I have with my 2005 Range Rover L322 is it shifts gfine for about 20 minutes then after it warms up if I slow down to make a turn or start from a stop the rpm's go way up when I try to accelerate and if I don't back off quickly it shifts down hard and throws a TRANS PROG error and goes into a limp home mode. Would changing the pressure regulating valve be the place to start?
Sounds like a problem in the A clutch, First place to start is making sure fluid level is full. If thats good, drop out the valvebody to see if the upper rear section of the valvebody is cracked, if thats ok, either A drum is cracked or the skinny o-ring is torn.
Dear Gary, thanks for your high end knowledge videos. Here in Germany there's no video like that. I'm a car mechanic and you gave me the confidence to renew my zf5hp24.

Hi Gary, I’m wondering, why do they use the scarf cut o-rings on the regulator valve? When I bought the kit, I thought they sent me two defective o-rings but it turns out that’s how they come. I’ve yet to install the new part but it seems to me the scarf o-rings won’t provide a perfect seal. Also, what do the sizing o-rings do exactly? I’ve not done anything past a filter and fluid change so all this is new to me. Thanks for the video and your time.
If your talking the Transgo kit, yes the scarf cut o-ring makes for easy install. Put some transgel or grease on the scar cut ring, put the o-ring on or resizer than put it in the freezer for a couple of hours and the valve should drop right in, there is no chafer so thats why it scarf cut, easy install
@@GaryFerraro Hi Gary, The problem with my 2003 XJ8 is, when I am in sport mode and I come to a near stop and proceed to pull away, the transmission kicks hard unless I apply the throttle very gingerly. It also ONLY happens in sport mode; in regular mode when coming to a near stop and then pulling away, I can put the pedal to the metal without an issue. What do you think is the more likely culprit: the pressure regulator or a crack in the upper valve body?
Hey guys, I've got an update since my replacement of the pressure regulator valve last November, and boy did it work a miracle! No more shudder after coming to a stop and hitting the gas. I can rag on the accelerator all I want in sport mode and the car acts just fine now. It's been 900+ miles since and absolutely no complaints. If you're having my symptoms listed in my older comment, MAKE THE UPGRADE! Thanks again to @GaryFerraro for his great video.
Hi Gary, Please Help!! I just installed this valve in my 02 Audi A8 as preventative maintenance with a filter/fluid service. I also only pulled the lower valve body. The car is new to us and didn’t seem to have issues prior. 75k miles. Some sludge on magnets but not too bad. The Tranny took 8.5qts to fill while running and pumping fluid in. I am now getting codes : P2725 pressure solenoid 5 malfunction. P0798 Pressure solenoid 3 malfunction. Did I miss/ lose a small part? Or make a mistake with assembly? It seemed to go together very nice, just like your video. Any direction is very much appreciated!
Hi Gary, Thanks for the reply! I installed the transgo valve. I don’t believe 8.5qts came out. The pan had been leaking quite bad when I started working on it so it’s hard to say for sure. I was doing engine work also and ran the car for a bit after the initial fill of 4.5 qts, before removing the plug and filling more, no more than 15 min. When I went to fill again it took two more qts before starting the car again. Also, there was a bit of wheel spin while filling due to the tires being off when I went to fill. Could these two things be of detriment? Final observation, the car will not go in to manual shift mode, it is in limp mode now. It will not let me shift through the gears. I thought I was meticulous and followed the instructions to a tee, there were no ham hands. Did I over fill? Or damage the transmission pump? Or possibly disturb wires on the valve body with my fill tube? Distraught…
Great video I have a 1990 f 250 3/4 ton 4x4 and E4OD The overdrive not engaging I had a trans guy inspected it replaced valve body w no results I also has steering column rebuilt still no overdrive What electrical can keep it from shifting into overdrive Thank you
On a 2002 BMW 540i with the 5hp24, i have the Problem wenn the car is warm, and it runs 20-30min in idle, the gearstick goes very very strong. When the car is cold after parking, the gearstick works perfect. Have you an idea?
Kinda sounds like a ground problem, if something is wrong with a ground, it may use the shift cable for a ground. When you say it's strong, is it very hard to move?
Yes, I have done this for quite a few clients already. This trans a few common issues but the A drum blowing up is what I mainly see when I get these jobs in
Sir: You seem to be the internet guru of ZF5HP24s....question: I have this transmission in my 2003 Jaguar XJ8 Vanden Plas with just under 31,000 miles. It seems to shift fine in all gears without jerking or slipping. But at 50 and above, under light acceleration, I get a low frequency hum that disappears either with downshifting to 4th or backing off the throttle. It seems to retreat to the background or disappear entirely under steady-state throttle at speed. I have been advised by a Jag Tech to just get a reputable transmission shop to replace the primary pressure regulator valve with an updated one, like the Transgo valve, and exchange the fluid with new, and that should take care of everything. Do you concur?
I never had that issue, the problem with the pressure reg valve is the bore wears out creating pressure spikes and blows the A drum. Has the car been checked?
@@GaryFerraro Yes. As a precaution, after buying the car at 30k miles, I had the filter changed and the pressure regulator valve replaced with what was described by a shop that does nothing but transmissions as an upgraded valve. I do know it was not a Transgo valve as I asked for that and the owner said he used a different brand. I did not insist as this is what they do for a living. Anyway, the humming noise remains, and the transmission continues to operate normally as best I can figure. No jerking in shifts, TC seems to do what it is supposed to, i.e. lock up and drop RPM a bit. My next stop is a drive-line shop to get their opinion unless you have further thoughts. It now has 42K.
Well, i think what i would do first is check the fluid level, when you check the fluid level see if it pours out like it's overfull, if it does then your pump is no good. If your pump is good, i would think something in the geartrain may have broke. If the fluid checks ok, maybe drop the pan see if anything is in the pan
The o-rings are the resizers, they hold the sealing teflon ring in place. The tolerance is very tight, the valve will not fit in the bore if you do not use the o-rings and if you do not put the valve in the freezer
Great video Gary. I have a 2003 Jaguar XJ Sport at 180k miles with the ZF5HP24, recently I have developed a whine while accelerating, seems to be present in all gears but only noticeable during low speeds. Shifts perfectly, no slipping, no faults, however a slightly hard downshift occurs once in a blue moon. Any ideas on what might be the cause? Thank you.
@Gary Ferraro Noise does change with engine pitch and can be heard through shifts, does not occur in park. I’m an apprentice mechanic however I’m not in tune with trans repair yet, and I’m not sure anyone understands the ZF’s like you do!
Hey, I've also got a whine, all gears (P/N/D), more noticeable after a 'spirited' drive. Mine is 5HP24A from 2001 Audi S8. Fluids+filter done recently using genuine ZF parts, procedure followed to the letter (slight drip at 45deg). Torque converter replaced 6months ago due to slipping, started whining 2-3 months after this. Any help would be greatly appreciated!
@@GaryFerraro Hi, yes, currently has ZF filter installed, filter that I removed was straight from Audi, they both had all the markings. Does sound very much like a low fluid situation but I've confirmed that it's properly topped up, even checked 1 week afterwards to be sure. What's confusing me is that a lot of people mention a whine when cold but goes away when warmed up, I seem to have the opposite problem. Thanks for the speedy reply, I want to diagnose as much as I can before going back to the shop that replaced the torque converter. Could a worn pump somehow be contributing to this? Or a fluid pressure issue? I've watched your videos on pressure regulator valves causing problems, would the bore being worn possibly cause this noise? Thanks again!
@ Gary. Hi Gary I have an 02 BMW 540 5HP24, after driving for an hour the shifts become rather slow, very lethargic. I checked underneath, and discovered I have a leak under my gear shifter( the o ring is bad). Do you think this may be the problem, I feel it’s low on trans fluid as it has been leaking for that o-ring. I will be replacing that o-ring and refilling the transmission. BTW awesome and great videos! You are the shit !
Hey Gary, been watching a lot of your videos thanks so much for taking the time to do them. I have the same tranmission from a 99 jaguar. It shifts smoothly until it goes from 3rd to 4th gear, then it feels like it is neutral and transmission fault comes up. P1733 code. You think this is from the common A drum failure or maybe something inside the valve body? About 6 months ago I did the transgo valve upgrade and fluid change as a preventive measure. Car has 85K miles. Look forward to hearing your expert opinion here thanks!
@@GaryFerraro Thanks for the quick replay. The Jaguar manual states: P1733 3-4 Shift Malfunction Initially the code was: P0734 Gear 4 Incorrect Ratio. I cleared it during trouble shooting and haven't seen it come back.
Hi Gary, what wonderful videos. A very big Thank you from Germany. I have the 5hp24 from my old e38 735i rebuilt now. It had a broken A clutch basket as usual. I cleaned all, replaced all seals and brass guides. Also all clutch bads and changed the metal plates that had the slightest view of a burn. Also I installed the Transgo Valve wich seemed to be a tight fit at the last little bit. It works wonderful now except when I decelerate and it shifts into lower gears, it sometimes still puts the gear in hard. But only on low or no power decelerating. What could it be? Should I change the Valve body with the transgo also into a new one? The Torque Converter was also overhauled here in Germany and I used only parts directly from ZF. Thank you for your help!
@@GaryFerraro yes. And its only on downshifts. The hardest shift happens when uphill shifting down into first. When Idling on slowdown, downshifts are well noticeable. Acceleration upshifts are super smooth. As all is new except the valve bodies, I was hoping for a complete soft shifting.
Hey Gary. Great video as usual! You gave me the confidence to rebuild the 5hp24 in my 2002 x5 4.6! Just had a question regarding issues post rebuild. I replaced all seals and clutches, and upgraded to the transgo pr valve. Now the vehicle has no forward gears, and reverse will only kick in above a certain rpm. Is there something obvious I might have missed? After a little while the trans will go into failsafe. Your help would be very much appreciated!
Yes, I changed it with an OEM unit, and made sure to check for proper movement when sliding it in. It seemed to go in just like you mentioned it should in your other videos.
@@jazzybraids well, you may have torn the skinny o-ring on the A drum, as far as reverse the F clutch and The C clutch are on in reverse, you have the seals on the hollow shaft? 2 o-rings and 2 teflon sealing rings?
@@edwincabrera6723 Thats your torque converter chattering, will not happen cold, converter is not commanded on til car heats up, may want to try changing the fluid and filter, get the parts from the dealer, they should be OE parts with this trans
@@GaryFerraro sorry maybe I spoke to soon. It is the part of the valve body that seem to normally Crack high pressure part of the upper VB. I haven't watched all your zf5hp24 videos yet to get exact name of that part... Thanks for getting back...

Does sound very much like a low fluid situation but I've confirmed that it's properly topped up, even checked 1 week afterwards to be sure. What's confusing me is that a lot of people mention a whine when cold but goes away when warmed up, I seem to have the opposite problem. Thanks for the speedy reply, I want to diagnose as much as I can before going back to the shop that replaced the torque converter. Could a worn pump somehow be contributing to this? Or a fluid pressure issue? I've watched your videos on pressure regulator valves causing problems, would the bore being worn possibly cause this noise? Thanks again!
@ Gary. Hi Gary I have an 02 BMW 540 5HP24, after driving for an hour the shifts become rather slow, very lethargic.
I checked underneath, and discovered I have a leak under my gear shifter( the o ring is bad).
Do you think this may be the problem, I feel it’s low on trans fluid as it has been leaking for that o-ring. I will be replacing that o-ring and refilling the transmission. BTW awesome and great videos! You are the shit !
I would certainly fix that leak first, refill with oil and drive the car see if anything changed.
Awesome, will do. Thank you good sir ! I appreciate your assistance
Manny Flo Welcome
Hey Gary, been watching a lot of your videos thanks so much for taking the time to do them. I have the same tranmission from a 99 jaguar. It shifts smoothly until it goes from 3rd to 4th gear, then it feels like it is neutral and transmission fault comes up. P1733 code. You think this is from the common A drum failure or maybe something inside the valve body? About 6 months ago I did the transgo valve upgrade and fluid change as a preventive measure. Car has 85K miles. Look forward to hearing your expert opinion here thanks!
Is the definition of that code gear error in 3rd?
@@GaryFerraro Thanks for the quick replay. The Jaguar manual states: P1733 3-4 Shift Malfunction
Initially the code was: P0734 Gear 4 Incorrect Ratio. I cleared it during trouble shooting and haven't seen it come back.
@@johnbaker26 but still has a problem correct?
Happens every shift?
Gary Ferraro yes every time it shifts into 4th I get a transmission fault. Sometimes the shift is a bit hard into fourth.
Hi Gary, what wonderful videos. A very big Thank you from Germany. I have the 5hp24 from my old e38 735i rebuilt now. It had a broken A clutch basket as usual. I cleaned all, replaced all seals and brass guides. Also all clutch bads and changed the metal plates that had the slightest view of a burn. Also I installed the Transgo Valve wich seemed to be a tight fit at the last little bit. It works wonderful now except when I decelerate and it shifts into lower gears, it sometimes still puts the gear in hard. But only on low or no power decelerating. What could it be? Should I change the Valve body with the transgo also into a new one? The Torque Converter was also overhauled here in Germany and I used only parts directly from ZF. Thank you for your help!
Do you mean this has hard downshifts?
@@GaryFerraro yes. And its only on downshifts. The hardest shift happens when uphill shifting down into first. When Idling on slowdown, downshifts are well noticeable. Acceleration upshifts are super smooth. As all is new except the valve bodies, I was hoping for a complete soft shifting.
@@GaryFerraro I could video the shift and send it over. Maybe thats easier? Were could I send it to?
@@GaryFerraro it seems its only going from 5 to 4th.
@@GaryFerraro also little rough from 3 to 2. Rest is super smooth.
Hey Gary. Great video as usual! You gave me the confidence to rebuild the 5hp24 in my 2002 x5 4.6! Just had a question regarding issues post rebuild. I replaced all seals and clutches, and upgraded to the transgo pr valve. Now the vehicle has no forward gears, and reverse will only kick in above a certain rpm. Is there something obvious I might have missed? After a little while the trans will go into failsafe. Your help would be very much appreciated!
How did the pressure regulator valve go in? What was original problem?
The valve went in without any issue, followed the directions to a t. The original problem was slipping between the 1-2 shift.
@@jazzybraids Did you change the F clutch piston?
Yes, I changed it with an OEM unit, and made sure to check for proper movement when sliding it in. It seemed to go in just like you mentioned it should in your other videos.
@@jazzybraids well, you may have torn the skinny o-ring on the A drum, as far as reverse the F clutch and The C clutch are on in reverse, you have the seals on the hollow shaft? 2 o-rings and 2 teflon sealing rings?
Why do i have to put the o-rings on the valve before the freezer, and than remove them bevor the intake? I need to do this the next days.
Silbereiche1 The o rings are the resizers. You will never get the valve in if you don't use them
@@GaryFerraro ok thanks for the explanation, by the way great videos👌🏻, it helps me a lot
Silbereiche1 Your welcome and thanks for watching
Hi Gary, got a 03 Range Rover w/ZF5HP24 has shudder bet 45-50mph, you think Transgo upgrade might do the job? TY
does the shudder feel like a wash board or going over rail road tracks
@@GaryFerraro it feels like going over rail road tracks, does not happen when cold..
Thanks
@@edwincabrera6723 Thats your torque converter chattering, will not happen cold, converter is not commanded on til car heats up, may want to try changing the fluid and filter, get the parts from the dealer, they should be OE parts with this trans
@@GaryFerraro ok great, will try that,TY
@@edwincabrera6723 sure, if fluid is old, may make the converter chatter
Where can I buy that part of VB? Mine Cracked ...
Lower front half where the regulator valve goes?
@@GaryFerraro sorry maybe I spoke to soon. It is the part of the valve body that seem to normally Crack high pressure part of the upper VB. I haven't watched all your zf5hp24 videos yet to get exact name of that part...
Thanks for getting back...

What’s the purpose of removing o rings before installing the pressure valve?
The o-rings are resizers for the teflon seals that gets installed on the valve
@@GaryFerraro So you put the seals on the regulator and remove them before installing in the vlave body?
@@crescentandstarglory No, I put the Teflon scarf cut seals onto the valve, I use grease to hold them in place, I put the O-rings or resizers on, I put the valve in the freezer overnite then right before I slide the valve into the bore I remove the O-rings.
@@GaryFerraro Thank you Gary. I am doing valve replacement. Your video came very useful.
Therion Vovin your welcome. Glad it helped
Help me out with a problem about my transmission please
Sure, What kind of car and what is the problem? any codes?
It dosnt wanna move forward or back. An smells abit burnt what you figure
@@buffykiller12 Are there any codes by chance, any noises coming from trans
No noise. An it’s a 2001 dodge truck 5.9 gas an it’s a 46re transmission. I was thinking it’s the solenoids pressure an governors
My jaguar bring this code p0783-07
