Slight Pulsating Hesitation When Cold
#23
So unfortunately not only did the re-flash not work, but it seems to have added a couple of new problems.
A small part of me worries I didn't fill the gearbox with the correct amount of fluid. Although I did my best to follow the fluid change procedure, anything is possible I guess. Could an under-filled gearbox cause these issues? Or is it more likely the re-flash?
- If I accelerate hard (but not WOT), the RPMs climb and then stall for a few seconds even though my throttle position doesn't change. This doesn't happen if put the pedal to the floor (and the switch is triggered).
- If the transmission is cold, there is a big clonk when I put it in Reverse.

Anyone have any ideas on the first issue I mentioned above? Now I'm wishing I would have gone back to the dealer who reset my transmission and asked why this problem started after they reprogrammed it.
Also, it seems like the clonk issue is avoidable if I wait till the revs drop when cold starting.

From my limted experience with the transmission here is what i know. I replaced my radiator and of course lost some tranny fluid. I forgot about the fluid loss and when test driving the car had a bad lurch and a couple other issues. I did the fluid check and fill spot on the book and added about 20 ozs. Evetything went back to normal....then a hard reset and drove according to brutals posted parameters and it worked beautifully....also the fluid itself is critical by using the right one...i used pentosin...it is zf approved...i cannot remember how to find brutals instructions...maybe someone else does...

It's very possible u under filled your transmission. R U sure the car was level, this is very, very,very important. Example if front is 2 inches off level, [to high] that translates to about 4 inches off level at the transmission fill plug. Which in turns would translate to your transmission being more than 1 1/2 liters low.
