Mickey Figueroa from Best Motor Works provides an overview on the ZF 6HP Automatic Transmission. This transmission was used in hundreds of thousands of BMW's, Jaguars, Land Rovers, VW's and Audis. Common failures and preventative measures are covered in this in-depth overview of the 6HP and how the service professional can use them to their advantage.
You sir are awesome. You exemplify the adage "Whatever you do for a living, be the best at it, and you will be successful". Thanks for sharing your knowledge!
By far the most insightful diagnosis of the ZF6HP19 gearbox issues.
Whoa . Spoken with authority and confidence . My trans shop service techs eyes just glazed over.
Thank you for this video. I live in Springhill florida and have a 2003 s type r. I drove the car daily and it has 220k miles on the car. I took it off the road a year ago and started a restoration of the car. The last thing I did was the tranny which o was getting a gearbox fault. I ordered the kit and I only changed the fluid with lifeguard and new pan and filter. The transmission improved but is still getting the fault. I'm kicking myself because I have all the seals and got lazy and didn't change them. This video is excellent because it explained how the seal work and I now understand it's function. I'm gonna drain and remove the pan and megatronic to change the valve seals and this one also. When I changed the fluid it was black and the car was not shifting properly . After the fluid change the transmission functioned as it should with a minor slip on 6th gear. I've done all the major work on the car myself as we do not have any qualified mechanics in our area. The dealer will not touch the car because it's to old ? Imagine that. I suspect this seal is bad and will know tomarow after I remove it. Thanks again !
Brilliant video on the theory / mechanism behind (and diagnostic implications of) a very much overlooked / ignored topic even by professional techs - transmission adaptation relearn!!
A very straight forward and knowledgeable discussion. Who talks about proactive measures these days? Only those who care about customers and outcomes!
This information is fantastic... thank you so much
This is a great video. Plethora of information presented in a very clear way. Thank you for sharing your knowledge in this obscure topic.
My e91 is jumping in drive when first selecting it,thanks for video,from the UK.
Genius video. Thank you!
Great video.lots to learn here
The Mechatronics sleeve, adapter and four seals are cheap and easy to replace in an afternoon.
PHATJANUS but how do you drop the mechatronic unit safely on an Audi? The wiring loom is integrated with the connector, so you can’t just pop outwards the connector adapter like the BMW videos show. I would like to take off the mechatronic / valve body on my ZF 6HP19A (Audi A6 Allroad 2007 3.2FSI - gearbox code is KHA) but scared that doing so will damage the wiring loom or connector attachment to casing. Thanks for any info
thankyou great everyone tells you about the problem but you told me how to diagnose the problem :)
Ok, i did a drain and fill on my zf6hp19 with the valvoline. I had a 4-5 flare before i did it and it seemed to fix that for me. No more ZF fluid for me, only Valvoline max life. I have a lot of miles on the car. Changed fluid and pan @ 150k miles with ZF and drove 90 K with flare if pushed hard it would flare so i just drove it easy for the 90 K to prevent it flaring. Drain and fill with Valvoline @ 240k. ZF fluid is about 5 times more expensive also
ken howorth what is the difference in fluid??
And why is the change helping you.
Interesting . I have a zf6hp26 transmission. I was going to go with the fluid you stated , but I didn't wanna question myself if there was a problem
Which I have . I have the entire kit and got lazy and didn't change the seal described in this video . I'll be under the car tomarow. Thanks 👍
Great video
Thank you
Great info about 6hp19 :) I have to look my clutch adaptations... in service we have an audi 3.0tdi qauttro which starts shifting very hard when warms up. There was an oil & filter change and mechatronic completly cleaned with new seals. There is no fault code...When transmission is cold, work OK... weird...
Does bad torture converter can cause mechanical /friction plate get burned and set a gear ratio code
Thanks 🙏
Good afternoon, Mr. Figuroa, I'm Portuguese and I have an Audi A6 2.7 TDI C6 quattro 6hp19 HXM and I've already spent a lot of money in a mechanic's garage and the problem is that it slips in 3. Could you help me? Thank you Helder Ribeiro
Btw, great video!
Hi, if you know, 2011 Audi Q5 3.2, 6sp transmission, what model ZF is it? 6HP XXX?
Can Transmission be carried over from one Q5 to another or additional things need to be done? Thank you.
Is the adaptation road test a joke? 9 times?
@Diagnostic Network. I was hoping you could make sense of this for me. 2008 535xiT, fluid change w/ all 4 Mechantronics gaskets and sleeves replaced, also a recent engine change. Car still feels a shudder in 2nd, slight uphill, light throttle...while WOT it slams pretty hard on 2-3...while cruising it sometimes feels like the trans is lightly coming on and off. I followed your procedure at least 10x, condition still exits...please help :/

6hp28 is not reliable ?
Are shown values the same for bmw transmissions?
Is this also the same with the 8hp55af? Have the same slow shifts light slip in low gears and no codes?
Thanks for the great video! Please please could you perhaps help me? I am always getting -700 mbar clutch E fill pressure after adaptation. I cannot find anywhere an information if this is outside of the allowed pressures. My transmission 8HP55 when the fluid temp is over 70-80 C, jerks slightly always before shifting 1-2 and 5-6. Very very slightly 2-3 and nobody can help me. Not even ZF official repair shop. Mechatronics has been checked and entire transmission rebuilt with new parts. No one knows why it jerks :-(
Hey Mickey, great video. I have a ZF6HP19A in my Audi S4. I got a new mechatronic and reset the adaptations. Car shifts great. My problem: when i am standing and shifting in to R or D with foot on the break, the engine rpm drop heavily and the whole car vibrates. When i drive and come to a stop there is close to no vibration. Only when shifting in D or R when standing. What can this be? Thank you so much in advance :)
Greetings from Berlin
What do you charge for a typical ZF rebuild?
Hi from dubai. Thanks for great information. Can you suggest why their is 2 sec delay in reverse when engaged. Its a 2008 4.8 x5.
Could be low fluid level.
Could a leaking or damaged seal cause a whine from the torque converter?
Hey did you find your whining problem
Mickey, thank you for making this amazing video - you have given me some hope that I can diagnose and fix my transmission issue. I have a 2007 Audi A6 Allroad 3.2FSi with KHA gearbox code (6HP19A). I’m experiencing lockup clutch slip in 4th, 5th, 6th at low temperatures and around 1400rpm with light engine load. Do you know this issue and the solution? Thanks
I have the same problem, most when is oil is cold, and the problem is the seals, lost pressure and transmission try to compensate increase the rpm, i replace the seals and solve the problem.
Fábio Leça thanks - which seals did you replace and what car do you have?
@@PVflying valve body seals, the seals the guy talk on the video.
Thanks, that’s interesting as I thought those seals control only gear shifting, not torque converter lockup clutch slip. That gives me encouragement that I might fix my problem by changing the seals. Is your car BMW or Audi? Thanks for your info
MerCury for you lockup the converter you need pressure, if you not have pressure the converter go slip until create enough pressure
Hi there, i have 07 750li with zf6hp26 trans,my vehicle start going into
park from drive aftere vehicle worm up,will not do it when it's cold,
error code iam getting is 4E89 SV 1 or SV 2 mechanically jammed.Have
you seen a code error like this. I replaced all mechatronic sleeves and
all solenoids, followed fill procedure engine off ,engine running at 40c
.Reset adaptation,still having the same problem.I recently replaced the
valvebody with used one but i used my old TCM module installed on it.
because I couldn't flash the one that came with the used valvebody
,still have same problem same error code. could you please help me with
this problem what it could be.thanks.
Have you found out what is was?
@@emilianoelsing4344 I end up rebuilt the transmission, after trying replacing valve body, TCM, all the solenoids, fluid, oil pan. Nothing help . I think mine had problem with oil pump or the torque converter. Even the shop who fixed it didn't tell me what was the issue. That is why they go for replacing everything ( rebuild ) it cost me 5300 with life time warranty. I know the vehicle is not worth that much but I already through a lots of money on it. Good luck to you.
i have a zf6hp19 with 4-5 flare when pushed hard but drives find when shifted below 3000 rpm. What do you think is wrong?
you will have to take a part the transmission and check Mechatronics seal and then check the e clutch bushing and the e clutches and check for cracks in the associated tube and housing.
Cool video,
I’m having problems where when it shifts to 4th, it will jump and jerk back to 3rd a few times and will go to safe mode and just stay in 3rd. Would this be the mechatronices/solenoid issues or the transmission synchronizer?
Stator bushing. E clutch burned.
Arno Bruynen
Thank you...
You’re very accurate. The drum is being serviced. Mechanical failure!
@@borinpich7420 Thank you Borin.
Now I understand a little more.
Again. You helped me get to this level of possibly understanding. Will try the seals and test the actuators first. Hope it's not e drum.
Plunked 3 or 4 times hard going into 3rd or 4th.
Last time hasn't come out of gear problem mode.
Found dipstick.
2008 750li.
Put about pint of red fluid in.
Stick has ATF-4 on it in little tiny letters.
On other end has min. and
max.
Fluid is tan?
Doesn't smell like cat stuff.
Smells like 5w-40 or 10w-30?
Somebody put engine oil in tranny?
More to investigate, decipher.
I can’t quite make out what is said between 3:34 and 3:40. “After we have completed repair of the separator seal, serviced the ??? and completed the adaptation”. What is the missing word denoted by ??? please?
ATF
Gary VanRemortel thanks Gary 👍
Hi @MrCurry, you can also turn on the closed captions (CC) for more info.
Diagnostic Network thanks for the tip 👍
