2008 Legacy GT 5EAT-S Stock Trans flush & Drive belts replaced in Dec at dealer and oil change w/ Castrol Edge While maintaining a constant speed (or very light acceleration), when the rpms are between 1500-2000, I occassionally get a strong rumble which feels like its coming from the transmission. While the rumble is occuring, if I give it gas or let it coast, the vibration goes away. I'm not too experienced, but it feels like the car is in 5th gear and there isn't enough power or speed to justify it being in 5th and it should be in 4th. (I hope that makes a little sense) Is there a possibility the rumble could be related to the TSB for the "Automatic Transmission Learning Control Procedure"? Has anyone experienced this before and/or have any ideas what might be going on?
go down the road of checking for a bad wheel bearing (see if is changes sounds while turning, etc). Those cars are almost famous for them (I have replaced 4-5-6 of them in the GF's lgt), and when the fronts go it sounds almost like a bad center diff. Russ
I replaced the front right wheel bearing in Dec. and I had all 4 checked about a week ago and they are all ok.
