have an 02 GT that my husband and i are working on. it is jerking when we have stopped and are begining to go on a downhill left hand turn progression and the RPMs jump to 500 and it hesitates going in left hand uphill progression. it only seems to happen with left hand turns. It also has a whine with acceleration and there is a very subtle rattle on the left side that we cant track down. It only lasts a few seconds and quickly recovers but has us stumped. We have recently done all the following: Replaced TCC and pcs selonoid, transmission fluid, wheel bearings. motor mounts, new tires, fuel sending unit, alternator, water pump, serp belt. Any thoughts would be appreciated!! Thanks
