Transmission jerking on 1st speed

[alawneh]

Finally ford company realized that they couldn't make a good solenoids, so now the new solenoids come from Germany with ford sticker....

Yes, but better off get the whole valve body:

FORD 6R60-6R60E VALVE BODY FULLY LOADED-MERCURY-FULLY TESTED AND COMPLETE! WOW! | eBay

It got cheaper, I paid $ 500 2 years ago.

Interesting, can the loaded valve body assembly be replaced without having to reflash the PCM?

Without reflash the PCM it will take along time to start shifting smoothly, and in some cases the problem will stay as it is.

 

[Christobal65]

I'd clear the KAM, which would force it to relearn everything, but does the valve body have to be flashed into the PCM for it to even work? I know some of the components require the PCM to be flashed for them to even operate.

This is hard question to me. May some friends answer it.

You can replace just the valve body without reprogramming the PCM if you swap the old TCM onto the new valve body. The rebuilt Mechatronic assemblies come without the TCM.
The original TCM is programmed with the PCM already.


That's what I did on mine and it works fine.

That's exactly what I was thinking and wanted to know! For $300 and a few hours of my labor I might have to try this and see if it fixes a few of my minor issues.

On the first gear the car runs like on jerky manual trans

Has anybody solved this problem? A have same jerking on the 1st gear it traffic jam on my 09 Explorer with 6r80, sometimes when you touch the gas while moving 3-4 mph the car jumps forward very hard, annoys very much

 

[94Eddie]

First thing I would check is the fluid level to make sure this isn't an issue. How many miles are on you Explorer and when is the last time the transmission was serviced? Have you done any software updates?

 

[Larkin_1]

Hello every one. Unfortunately still have this problem for about 10 years. Even changed the valve body-no changes. Makes me nervous, thinking about selling the car because if this

Try resetting the PCM. Basically, Remove the Negative Battery lead and isolate it. Then connect a wire between the Positive battery cable and the Removed Negative Lead (Wire NOT the terminal). Leave it that way for about 15-30 minutes. Afterwards, remove the shorting wire and reconnect the battery. You will then have to re-train the system.
For the idle (let it idle for about 5 minutes), then turn on ALL accessories (Lights, radio AC's...) and let idle a few more minutes. Then set up your car for about a 15 minute drive. Start slow and let the computer relearn the shift points (try to make sure you run through all the shift points). Then take it out on the highway. This might need to be repeated a couple of times (relearn process).

did anyone ever try this? seems like a risky procedure

To make it simple
Ford made the design change on 6r80 ,clutch packs changed to eliminate the 1 to 2 or 2 to 1 clunk or jerk.

They added some kind of racheting mechanism to the gearbox.it works similar to bicycle chain gear idea.

If the racheting mechanism gone bad in 6r80 you may get this kind of behavior ( with the leadframe replaced) and only transmission overhaul will help here.

On 6r60 only the TCM does the job of this clutch ( that why the 6r60 will never change smooth the first two gears upshift and downshift but it could be improved by using latest calibration file and rebuild valve body )

i have a 6r60 that was just rebuilt and is now having that jerk problem . the other problem is that we cant get into the TCM programming because of possibly some issue with the main PCM computer. Maybe it's wiring or maybe a software problem. I am trying to figure that out. DOes that fix with the battery terminals actually work? (It sounds risky). thanks. also how can you get the calibration file in there? Do you know someone in Haifa or the north that can do this kind of thing?

 

[Bazz270]

Any Ford dealer could do it via Rotunda diag tool.
The calibration file only could be downloaded on Ford Oasis server.


And no ,disconnection of the battery wont erase any memory ( tcm memory stored inside EEPROM KAM memory chip inside the TCM,not affected by battery voltage ) .you should do it only using suitable diagnostic equipment

You can drive without the latest calibration file, if the TCM was reused ,make sure to reset the KAM and perform full transmission relearn.

If the TCM calibration file was fully erased somehow you will need Ford IDS tool to install the calibration file

 

[Bazz270]

But if you have any CAN module connection related codes ,or the TCM connection issues fix em first

Use launch or autel /forscan/ford ids

When I bought my current Mountaineer with around 100k miles it have a shifting issue. I did two pan drops within 5k miles, cleared the learned data and completed the idle procedure. This got rid of the shifting issues and it is running fine now with 152k miles on it. Maybe it was the fluid changes that removed the shifting issues but I can't rule out the data clearing had an effect too. The 6R60/80 transmissions are sensitive to old and/or low transmission fluid. Many times a pan drop and fluid change will take care of problems. Also, don't ever do a flush of these transmissions. They have a temperature valve on the line that runs to the external cooler that only sends fluid there when it is up to operating temperature. Most shops that flush don't ensure the operating temperature is reached and this causes the new fluid to bypass the transmission and dump into the waste container.

 

[Bazz270]

Yeah
In most cases pan drops plus relearn will help
In my case ,valve body separator plate and the accumulators gone and the pressure dropped caused clutch A slip

Ive changed the valve body ( reman by. central valve bodies using sonnax parts) and the seals.never seen 6r60 that needed full overhaul including clutch packs,bushings and seals.

The transmission itself now shifts almost like new with approximate 200k miles on it

I cant access the pressures values on the clutch packs using launch tool like in the BMW ZF but assuming the transmission shift smooth now ,the pressures are good

I tried re setting the Learning using forscan but only got an error. My mechanic who rebuilt the tranny took the car to a Ford garage and they spent 3 hours trying to access the computer and reset the TCM and they couldnt. THey just gave up . SO my newly rebuilt tranny (not cheap) is jerking. ANd they just basically gave up on it. I have to take it now somewhere else and see if I can solve this connection issue. What a pain in the butt
