Diagnosing Ford F150 Harsh Downshift/Drive Apply
Vložit
- čas přidán 8. 07. 2024
- A customer arrived with a 2012 Ford F150 truck equipped with a 6R80. The complaint consisted of a harsh neutral to drive as well as an aggressive coast down and kick down into fourth gear. There were no trouble codes present and the condition happened rather quickly.
A systematic approach was used to determine exactly what the problem was as opposed to just replacing parts. Ultimately the problem ended up being a bad SSA solenoid.

Wow - this is probably the clearest video of diagnostics and repair ever posted to the internet. Excellent job - thank you so much!
This is one smart dude! Thanks for the video and explanations.
Glad I found your channel. I have a 15 transit 350 with 3.7. 6r80.
Codes P0706,0707,0712,0715
I have been having this vibration sound for a long time, I would describe it like a low bass sound, from big sound system. It comes and goes at any speed above prob 40mph. It will sometimes happen every few seconds and it last for a second or 2.
We now have 135k and it started 50k or so ago. I have taken it to several shops and they all say it’s tires or shocks or something and never fixed the problem.
Last week I was headed up in elevation on a road trip, no trailer. And I was noticing the rpm would bounce +\- 200, when the sound happens.
Then, the sound went away. Approx 50miles later I noticed fluid getting on my rear Windows. I kept driving and made it the next 100 miles to our destination. During the 100 miles, it didn’t ever shift down when pulling hills, it stayed in 6. Even if I manually tried selecting another gear, it wouldn’t allow me to change.
After getting into town, I shut it off and when restarted tried, it shifts hard to reverse and drive. It operated fine in R. But feels like I’m still starting in a higher gear.
We trailered it back to our town. Where I now have it and am ready to work on it.
What are your thoughts? I purchased: lead frame, case of fluid, filter, and it was all here by the time we got home.
Now I’m thinking torque converter too.
Or am I too far into it and should just bite bullet and order a trans?
Where would the fluid have come from?
It looks wet on bottom of bell housing…
Thank you for sharing and for taking the time to explain things. Local parts store scanned my 2009 F150. U0121 (ABS lost comms with abs “non mil”) Where i’m confused is it stated on his scan tool to replace TCM and reprogram TCM. Which had me thinking…I do recall that my truck will occasionally have longer shifting leaving for work in the morning.
Awesomeness, keep up the good work 👍🏻 !!!
Thank you Mike outstanding video mark mangano dependable auto
Thank you, this is my exact problem on 2015 f150
Thanks for sharing your knowledge
Awesome information 👍🏻👍🏻
You guy's are great thanks for in info haven't done many trans since fmx,c4,c6 all good 3 speeds a few fordomatics 2 speed thanks again
Thank you that’s great info
Thank you sir
I wonder how much the new fluid helped in solving the issue?
I have a Ford 4r75e transmission that shutters and stalls when brakes are applied. What causes that? Thank you for sharing.
That’s good to know. I really thought it would be the connector assembly. I’ll have to look into the SSA on my Raptor. Does the same in 4th gear. Thank you!
I've been having the same issue on my raptor. Did you find a solution to your problem?
@@eduardobanda1721 found the problem? Similar problem in my GEN 1
@@Christian.Alv6 I did. I had gotten a tune from Cobb so I had to reset the transmission tune and that fixed it. It was an ECU problem after all.
@@eduardobanda1721 mine does that also after i tuned it what exactly needed to be done
How did u get it reset if u don't mind me asking? I have a bully dog, got my transmission rebuilt and having same issues. Taking it in for the recall maybe they'll reset
Awesome explanation!!! Thank you for sharing your knowledge. My 6R80 hard shifts when cold from 1st to 2nd gear but only do that 2 or 3 times after I have stopped twice or three times during the first driving cycle of the day? Why not on the first time shifting? Why only after the truck is being parked for several hours? (usually overnight) Can anybody explain this? Once I have gone thru the first driving cycle of the day it goes away? Thanks in advance...
Im having the exact same issue with my 2012 f150 ,i wish you're shop was here in las vegas.
I’m having the same issue (harsh shifting) here in Vegas as well. Took to dealership and they’re talking about rebuilding / replacing transmission.
when you see odd man you know that you car in good hands good jop👍
I laughed when i seen the guy, but pretty smart fella. Looks like he had it nailed off the get, thanks for the video. Seemed like a lot of labor for a shift solenoid?
How do you calibrate the solenoids? Please help
My f 150 2009 love this truck my problem is that starts and goes to all 6 speed but than if I stop o slodown and take off it feels like is in 3rd gear. Take off in third gear and don't upshift o down shift have to stop on side of road turn engine off. And is ok but than after driving light on dashboard
Can it test good and still malfunction on operations? sometimes electrical can skip a beat?
hi do you know howto transsfr part to 2016 5.0 6 speed hard shift 2nd to 3rd
Mike....would replacing the lead frame give one the same results?
Thanks
So which solenoid did you replace exactly and what part number
Simple excellence by men the lawyers, doctors, and politicians foolishly do not consider to be "Professionals" on par with themselves. I also learned this is NOT something I'm going to be doing by myself on ramps outside on the dirt & gravel here in Montana.
Hello from Canada! Thanks for this great video!
F150 3.7L 4x4 mfd 03/11 SR80
1-2 shift is rough all the time, under hard acceleration it’s a violent shift into 2nd. No wrench, no codes at all for transmission.
Ford replaced the lead frame, No difference. Now they want $3400CAD just to open it up to see what’s wrong with it.
I just bought the truck a month ago and really regretting it. Any advice on what might cause this?
A 1-2 upshift involves the C clutch circuit. Items such as the SSC solenoid, valve body, C clutch pack or computer signal could cause this issue. Resetting the computer shift adapts or checking and if needed replacing the solenoid/valve body would certainly be a first step. You may want to visit a transmission shop.
If I was you I’d buy the sonnax accumulator spring kit and get that first. It sounds like a timing issue to me.
This guy knows his stuff! I have a weird issue with my 2011 F150 6r80. In the morning, the first time it shifts from 2nd to 3rd, its a very harsh shift. I usually drive slowly out of my neighborhood, so it's not an issue with agressive driving. After that first shift cycle, it's fine for the remainder of the day. I had fluid and filter changed less than 10,000 miles ago, and the shop I use, I trust implicitly, proper Ford LV fluid and motorcraft filter were installed. Truck is driven gently, and exhibits no issues other than this. No warning lights either.
i am having the same issue, seems to be related to trans temp. over 80 and starts to shift fine. 2013 F150 6r80
@@salcutrona7235 here's a free solution, I drive it slowly, allowing it to shift from first to second, then maintain that speed, not allowing it to shift to third. I have a stop sign three blocks from home, as I stop the truck, I shift into reverse and back up a few feet. Then shift back to drive, and there is no harsh shift from 2 to 3. Works every time.
Mine's been doing that for years, I'm at 180k miles. Usually what I do I just let it run for a few mins after turning it on and it will shift normally. Just let the heat and pressure build up a bit. Based off what Fordtechmakuloco says it could possibly be a cracked transpump adapter that sits under the valvebody. I haven't gotten around to inspecting it yet to verify. It's a bit annoying but at this point it hasn't seemed to have gotten worse. I love my truck 😊.
@@markk3652 thanks that's what I have been doing. it works compared to the alternative
Grease that spline
I have the same issue but 1st & 2nd gear harsh shifting, changed solenoid valve and it shifts fine and in the morning back to the same issue and the transmission tech guy told me it’s the valve body $1100, the transmission is fully built to handle 1000hp. Or he said it might be a tune.
Harsh shifting can be due to computer programming, electrical components or a valve body. Validate that all computer updates and shift adapts have been performed. If so, solenoids and connectors should be tested and if okay will then point to the valve body.
@@TransmissionDigest we finished checking solenoids and valve body last week and they all check perfectly. Then, back again to the tuner and thanks God he managed to tune it and now it’s shifting almost like stock.
Thats parthcles from the fluid sticking to the selnoids.
Replace the lead frame and use the foam gasket .
I have a 2013 f 150 that makes a whooping noise shifting from 3 to 4gear. It also sometime has a hard shift through the same gears. I took it to a local Ford dealership and they was no help at all. What do you think?
Mine was doing that for a like 6. Months untill transmission gave out. 4,5,6 were burnt. Got it rebuilt last week and still having a few issues gonna take it in for recall, then go from there
Great video!!! I wish you were local. Can the adaptive shifting be reset by just disconnecting the battery or does it need to be done with a scanner? I have a Ford F150 (6R80) built on 08/12. Thank you!!!
Here's a procedure I found with a Google search:
www.ford-trucks.com/how-tos/a/ford-f150-f250-how-to-reset-adaptive-memory-359981
I believe Forscan can reset the adaptive
Cool pants !
ford is replacing my molded lead frame on my 2013 f150 this week. Extended warranty covers 2012 and 2013's at this point I believe.
I have send my car to the Service Centre for replace the rear tyre sensor, and after that the mechanic suggest to update my car software for better condition
After finished software installation, there are two symptoms coming out
• Car temperature indicator go to maximum level
• Very Hard Knocking when I shift N to D gear
Senior Mechanic take over this to find the problem occur and made some software alteration to normalise the condition.
The senior mechanic can only normalise the high temperature problem but can’t soft the hard knocking problem and they said that they could not replicate the problem
Any idea what it can be. It only happens in first gear. All the rest of the gears shifts smoothly with no problem.
This happens even when the car has warmed up and even after an hour of driving.
My 2017 Ford ranger XLT AUTOMATIC is doing the same thing. Sydney Australia
The issue covered in the video applies to a 6R80 which is used in a variety of vehicles. Before changing parts verify that it is the same issue.
What do you say about the recall lead frame problem?? Could it cause total transmission failure if shifting in acceleration from 55-65 on dry pavement back to first??!
Transmission felt great till the day it went total failure, and was when accelerating around 55-65mph and just went dead.
I’ve had a lead frame problem with mine, I would be driving on the road everything on my cluster would stop working. I could be in 5th and decide it would downshift to 3rd without changing speed, so I would say it’s not safe to drive, I called around for a lead frame and no one can get one because of COVID, everything is on back order, if you still are looking for one go to summit racing
I'm having a harsh 5 to 4 shift like in your video. Is this a similar solution for a 2015 f150
How much does this fix cost? My dealer gave me a quote for 2k CAD . 2011 Ford F-150 fx4
This particular shifting issue could apply to any year of 6R80. Proper diagnostics is always the first step though.
I have a 2021 F-150 XLT 10 speed and I’m stating to have the exact same issue between 3rd and 2nd or when it goes from 3rd and skips to 1st on downshift…only 27k miles…Ford is telling me due to supply chain issues they could have it work weeks…..
My 2007 Tacoma computer controlled transmission still works flawlessly ,retired transmission rebuilder.
Good day sir, I'm from South Africa, i drive a 3.2 5 cyllinder 2011 Ford Ranger with identical issues that you describe. My vehicle has also that heavy lash when it shift between fourth and fifth, it's also very hard on the downshift.Would you suggest that i also try and replace my SSA Solenoid? The garages here want to charge me R 25000.00 South African rand, approximately 1740.USD. Any suggestions? The vehicle has 237002 km on the clock already.
On the assumption that the vehicle has a 6R80, shifting issues (up or down) can be attributable to computer programming, solenoid malfunction, valve body wear or the specific clutch assembly. The process of elimination starts with ensuring a proper computer signal which requires a scanner.
Assuming all computer signals and transmission line pressure are correct, the next step would be to validate proper solenoid operation which will also require a tester. Randomly changing solenoids can become costly. With the mileage on the vehicle a worn valve body is also a distinct possibility.
If the problem appeared suddenly and no other work had been performed on the vehicle, trying an individual solenoid is a valid approach.
If the price quoted by the shop is for a new valve body with solenoids they are just trying to err on the side of caution.
Without the ability to test specific functions, replacing parts usually relies on luck to resolve the issue.
Hi Johan Gerber, Did you resolve your heavy shift Issue by replacing a solenoid? I have an 2016 everest with the exact same issue.
@@mariuscoetzer8553 Hi Marius, No, i did not. Eventually i took the vehicle to Mayfair in Pretoria, they rebuilt the whole box for an arm and a leg. It went well for seven months, now it's really starting with stupid symptoms again.This time i'm going to purchace a rebuild kit from the |USA and do it myself. You just can't rely on somebody in South Africa to do it right the first time.
What if it works and then after a few minutes no movement at all forwards or reverse
Let it cool down and it go in reverse and not forward at all
It reads transmission Fault
Hi guys, I have a Ranger 3.2 with 6R80. Can someone help where to buy it? Ebay unbranded are a good option? Has someone use it?
Hi there, we asked your question to the folks at Transtar and they said that the TS Part #’s will be 95421B / 95422B / 95423B / 95424B / or 95425B depending on the customer's band number on the solenoid. Hope that helps!
I have a 2013 f150 3 weeks before the transmission recall came out, my truck shifted to 1 st gear going over 70mph and destroyed trans $4600.00 later and 19 days before the recall they will not honor the recall and refund my money!!!!!! this only the 23rd Ford vehicle my family has purchased in the last 25 years NEVER AGAIN.
my 2012 is going from 6th to 2nd at 50 mph, just took it in. Im sorry to hear that man. Ill hopefully get the recall applied
Damn man that sucks. Most of my family drives Fords too. What brand did you switch too?
Ford service sucks. They will fight you on any little thing so they don’t have to pay for there own mistakes. Crazy!
I bought a preowned same year do they honor the recall even if I’m not original owner? Was otw to work this morning and mine was just downshifting super hard and I turned around called and asked my mom to use her car cause I would have to hit i20 to get to work and I didn’t trust it shifting that hard doin 70.
Man that had to have been scary at 70 miles an hour dropping to first gear if you were in the rain or snow that could’ve been a very bad accident.
I have a 2011 6.2 with 267,000miles. My trans started acting up March 5 2021, the wrench sign and engine light came up while waiting to get gas, and code p0770 came up with a scanner and then March 8 it disappeared, March 10 driving on the freeway it was stuck on 3rd gear and wouldnt up shift, had to pull over, turn off truck then drove it around the street it was stuck for awhile and then started normal again but with engine light still on.
Same here, expect harsh down shifts and stalling when you go over 50mph, stay on the slow lane and be ready to pull over
The video in question relates to a very specific condition. Multiple symptoms should first be addressed by reprogramming and resetting shift adapts which require a capable scanner. Once done, if the conditions still exist then focus internally. One solenoid will not cause multiple symptoms however a bad lead frame certainly can.
@@TransmissionDigest my trans is all okay now. Hasn't had problem since I posted the comment.
My 2016 F 150 with a 5.0 at hwy speeds ( 70 to 80 ) sometimes has a harsh down shift from 6 to 5 when you normally accelerate or start up an incline or hill . It has 40,000 miles and was serviced at 25,000 with filter and mercon LV , any ideas ? Otherwise it preforms normal. Never any towing !
I have a 2016 3.5... same thing from 5th to 4th gear. What ended up happening with yours?
@@davidg5965 It stopped by itself don’t know why ! Try servicing it , it won’t hurt !
@thomasdaum1927 I've thought about it for sure. I did some digging as well and there's a TSB numbered 15-0142 which is specifically a 5-4 harsh shift and I had my pcm flashed in like September with a new throttle body so maybe hopefully that's the issue? Imma check that out and have a transmission service as well.. thanks for the tip!
@@davidg5965 👍
The whole brand new valve body is actually cheaper than the time and cost to diagnose the valve body, my opinion just buy the new valve body and just pay for the installation.
If you were paying attention...the intent from the beginning was to diagnose properly to avoid “throwing parts” at the vehicle.
Why can't my fix be that easy ?
Throw parts at it the hope it fixes it typical

im confused so the selonoid you tested and said was ok was not? ssa whats that mean
90% of the shops just said rebuild the transmission is bad
Yeah I took my 2016 to the ford dealership and they wanted to drop the transmission instead of checking what this guy did.. they just want to get paid
