Agree. E Clutch first thing to go on these transmissions unfortunately

 

Should've tried TCM reflash before fiddling with the valve body. Hoping you also changed the bridge and tube seals. If not plan on doing so ASAP and buy genuine ZF parts, not aftermarket..

 

Catching up on this post, awesome. For anyone's that does not have IDS/SDD here is what you do.

No sports mode.

Drive gently for the first 50 miles (critical) ensuring shifts (1-2, 2-3, 3-4 and 4-5) all happen around 1,600 rpm (SC cars - around 1,400 rpm; FYI not easy but doable).

Same with downshifting, especially 2-1 downshift, no gas, light braking.

Also, when parked, when trans is warm. Shift from P to R, then N then D then 2, 3, 4, 5 and back to D, then N then R then Park with 7 -10 seconds between each shift point.

Do that 3 times...

After 50 miles you can get a bit more aggressive but still take it easy. Do so for about another 200 miles.

Drive normal, not aggressively. No hard upshifts/downshifts and no "sports" mode throughout the above.

 

The later IDS reprogramming seems to not need CODED ACCESS and the drive strategy of the early configuration is changed but you can still drive the car as per the TSB S303-17 to obtain the desired result?

I left the dealer in 2006 so I ONLY did the drive cycle in the TSB S303-17.

 

Awesome! Thank you. That's a little different than the procedure I followed, but I will also follow these guidelines. I didn't know about the shifter procedure. I'll do that after work. I did notice it's been a little slow to shift in to reverse.

Thank you for your help!

 

I would have much rather had the TCM reflashed, but I couldn't find anyone to do it. The local dealerships told me they wouldn't touch it due to age. In hindsight, I could have bought the stuff to reflash it myself for the cost of the valve body, solenoids, and service parts.

 

You need to CLEAR ADAPTATIONS and THEN perform the 'drive-cycle'.
Your TCM already has the 'bad-habits' set in adaptations.

 

I did.

 

no definitely meant flour!

 

blocked solenoids and piston wear is pretty common. throwing in a VB in combo in with a reset will keep clutch adapts down

 

The software is complicated but I have always found that IF you try a RESET ADAPTATIONS and the software is 'out of date', the IDS will state that the TCM will need a REFLASH. IF the software is the latest that the diag computer is loaded with, the ADAPTATION ONLY will proceed.

Sometimes the ECM and TCM reprogram alert will come up on the screen and the software will also recommend that the procedure will take a LONGER TIME and a suitable battery maintenance device is attached because BOTH ECM and TCM need updated software.

The software always looks for the version loaded into the modules and will recommend that a NEWER VERSION IS AVAILABLE and will pretty much demand that it be installed before the CLEAR ADAPTATIONS be started if older software is found.

IDS 118.5 is the LAST version and I'm sure SDD revert Legacy IDS is 118.5.

If you actually CLEARED ADAPTATIONS with WDS/IDS or SDD revert to legacy IDS then you will NOT need a 'reflash' of the TCM. (PERIOD,END OF DISCUSSION)
The CLEAR ADAPTATIONS will proceed without any updated software required.

The TCM will 'learn' the new adaptations over time but Jaguar did offer some guidelines to speed up the process.
It can also 'learn' bad habits if the guidelines are not followed.

 

Can you post the link to the post on the Land-rover forum for solving the problems you mentioned with adaption? or perhaps you can post a copy of their suggested procedures.

Thanks

Actually, it didn’t work. I’m still having issues. I’m ordering the Mongoose IDS/SDD tomorrow in hopes I can get this thing to relearn using factory procedures.

 

Have you seen the attached flow chart from Jag about the ZF transmission. On getting the adaptions to take hold there is much coasting to get the 3-4 shift to work correctly- so when you get to where the shift should occur (depending on speed) you just lift your foot off the accelerator and you will see the shift taking place. I have the SDD and it is still hard with that to get the 3-4 to set correctly. You will generally find, that depending on your speed that the 1600-2000 rpm is the toughest spot to get it to shift correctly. Above that - it seems to work fine, but you still have to work through the adaptions. for the others before that. Sometime doing it as a manual shift at the right point can help as well. Once you get the mongoose cable, you might consider checking the version of software of the TCM and even if updated re-flash anyway.

This link can be helpful to know more about your transmission, but beware that these guys are into fixing or replacing the valve body even for simple things- it is like an obsessions with them. In my case I spoke to them as someone, thinking they were doing me a favor, had erased by TCM adaptions and I was having some difficulty getting them back.

So read with that caution in mind, but still great info that could find you some solution and give you a better understanding of your transmission.

You can also reach out to ZF as I did and they gave me the exact same advice as Brutal did.


I wrote them originally at passcarinfo@zf.com and thereafter all emails were from zfservicedesk@zf.com. I would send to both your exact symptoms.

Their NA phone number, where I talked to their service desk is ZF Services North America, LLC., telephone: 847 478 6868.

Give them details and they will have a reasonably good direction for you. They are happy to help.

Based on your description of the original gripe....were you unaware you could just hold it in 4 for the first few miles until the xmsn fluid is warmed up?
Then the glitch that they relabeled a "feature" is defeated.
