On Monday, I took our 2008 Mz5 to the shop for a transmission issue. Car was not shifting between gears smoothly, especially 3rd to 4th. There would be a bit of a lurch, especially if giving it the gas like to merge on the highway. Car was holding revs too long when shifting 1st to 2nd as well. No check engine lights.
Last Sept I did a full 9qt. Trans fluid flush and replaced fluid with Valvoline Import M-V (multi vehicle). I have also replaced both engine mounts and the trans mount.
Turns out it was a bad trans fluid pressure switch and the car was running the trans at higher than normal pressure, per one of the codes the car threw for the mechanic. Replaced it and it drives fine now, $240 later.
