I hope that makes sense...but you can hear the engine go "ruumm' *once...then "ruumm" twice and on the second rev is when it took off... anyone heard of this before? has happened a few times already thanks

Sounds like the ASC doing its job.

adaptive shift control - basically there to adjust to the driver's driving style.

honestly OP, i really think your car is okay.

the dealership you went to probably quoted you on some outstanding (and unnecessary) jobs.

If you manually shift; you can his rev limiter @just over 7500, but leaving in D,,,that should not happen// also ; the light is an adjustable shift light... Mines set at 7900 & sometimes flashes @7400,rite before shift.

Car is at dealer as we speak. Issue was duplicated by tech! So far my 12 was behind 3 ecu updates and 2 tcm updates. Didnt help... Lets see what happens....

GZ3 · 07-07-2015, 04:37 PM

UPDATE*****

Pulling the oil pan for metal shaving on the megnetic points... I did let the tech know i recently changed my oil... They are going to goahead and replace the valve body which includes the tcm. If the issue persists, the whole tranny is next
