Thanks for your note on my issue. Yesterday I had my VERY TRUSTED mechanic check the transmission fluid, and it was full. His suggestion was to take it to his go to tranny shop and have them drop the pan and look for shreddings etc and see if anything is clogging the filter.
redbull 325is: There is definitely a noticeable "jolt" at low RPMs when it drops a gear. I am certain that it is abnormal. It happens rolling at low speed (10-15mph) as well as from a dead start. Also, there's a delay in engagement when shifting from park to drive (about 1 second). When shifting from reverse to drive, there is a longer delay (around 2 seconds). Again, there don't seem to be any symptoms above 15 mph that I notice.
Curious if you still think the firmware update would help?
