I am starting a new thread, as my situation is somewhat different from other postings.

I hope ewill3rd or other technicians can respond!

Two months ago, my formerly-seamless trans ('04 V-8 RWD; 22,000 miles) started to do what seemed to be rough shifts on light acceleration and coasting to a stop. The nature of the jerks, etc., led me to believe torque converter lock-up clutch action. Then, after a two day 1,100 mile trip, the SHUDDER, lightly accelerating up slight inclines and then on the flat, began. After the return drive, I went to the dealer for repair. I did not mention the initial jerks, as I did not want to confuse the service department into thinking I needed the dreaded ECM reflash for AWD driveline problems.

THE REPAIR, per the work-order/invoice, and QUESTIONS:
PIP3456D DOC 1866746..REPROGRAM TCM/ NO CHANGE/REPLACE TORQUE
CONVERTER & FLUID...
1 96042553 T/CNV REM..........Does the "REM" mean remanufactured, or
is it new?
1 96041856 SEAL..................I assume this is O.K.
2 88861045 FLUID.................Does this mean only 2 quarts of fluid were
replaced?!? Is the fluid Dexron VI?
PIP3456D procedures call for flushing the trans and refilling with as
much Dexron VI as possible. The trans holds 9 quarts. How could only
2 quarts do the job?

NEW PROBLEM and QUESTIONS:
Since the repair, a new intermittent problem has arisen. When the trans is
in Sport Mode, it may not hold in gear when accelerating briskly, then
backing off the accelerator; it acts like normal mode. And it has refused to
downshift manually at 40 mph, coasting, even though the Sport Mode light is
on; I can pull the shift lever back, but their is no connection. QUESTIONS:
What might the cause be? Could it be the result of the dealer's "repair?" Is
it easy to fix?

Comment: The "Coaster Brake" (transmission brake) action is now much more pronounced coasting downhill or to a stop.

Any assistance is MOST APPRECIATED!

I found an answer to one question; the fluid part number is for one gallon. So, the trans was refilled with 8 quarts of Dexron VI. Still do not know about the missing one quart; remaining fluid in the trans that couldn't be drained out?
Any answers/comments are greatly appreciated.
Thanks!

In response to the initial jerking, my '05 SRX V6 RWD suffered from that problem. I took it in and that diagnosed and replaced a "cracked differential bushing." The transmission has been smooth ever since. I don't know about the shuddering, but that's how they resolved the problem of the jerking on my SRX.

Was "jerking" at low speeds, while coming to a stop??? I think I may be experiancing something of that nature.

I'm taking mine in next week. Does anyone have answers? They would be helpful in dealing with my service dept.
BTW, did the repair fix your shudder problem, K-1?

The shudder problem was eliminated by the "fix." The jerks upon light acceleration and low-speed decelleration experienced prior to the shudder episode were also eliminated.

I'm experiencing what sounds similar. When braking I get a shudder, like the torque converter isn't releasing. Also sometimes get a clunk feel when coasting to a stop. Dealer tried telling me that the front brakes were slightly warped. No explanation for the clunk. Mine is a 2005 V6 AWD.

I just got the car back that was in for the shudder problem. The dealer said that the torque converter was failing internaly and had to be replaced. However I haven't noticed any changes, :ill: still get the shudder/light jerking wile stopping.

Anybody out there had it in for the second time, for the same issue??

Thanks

anyone???:ill:

I have 04 V8 AWD that had shutter just when you where going up grade at low speed and also had moan at times at about 40-45 mph. Had converter changed at 19000 miles it's got 20000 now with no problem. It never had shutter on stopping and TSB doesn't say thats a problem with v8.

As you brake to a stop is the engine returning to idle or is the computer holding rpm's up?
I'm picturing a power on stop with the tranny acting as if under load by downshifting and fighting the brakes.

I think the rpm's go down, nothing unusual....
It really feels like they (dealer) didn't replace anything, or whatever they replaced failed on the spot:hmm: I do believe they did the work.
First thing I got the car back I tried to see the difference and there was none.:hmm:

I would have taken the car back right away but frankly, I really love it and want to enjoy it, and not the loaner. It doesn't even bother me that much, I just want to get things fixed before my warranty expires.
However a new 07 SVT loaner was pretty nice.

Anyway. Maybe next week I'll take it back.

Thanks for your thoughts
