Transmission Repair Shops?
Looking for recommendations on transmission shops in the Portland area!
A little background, I have a 2001 WJ (Grand Cherokee) with 4.7L and Quadradrive (545re transmission), 96k miles. It has been shifting rough occasionally form 1 to 2 and then also when shifting into OD. When cruising in OD there is slight surging but no noticeable change in RPMs. Idles and runs fine, accelerates fine. No codes being thrown at all. Took a guess and changed the TPS, unhooked battery too, no change.
At a loss of what to look at next. Last changed transmission fluid 36k miles ago and it still looks clean. With no codes, not sure what to do. Can anyone suggest a reputable shop that really knows jeeps? Thanks for your help!
