You sould have been moore frequent on your transmission fluid changes, and you shouldn't have taken it to Jiffy Lube either. Your best bet is to drain and fill the trans fluid run it shift gears. Drain and fill again. Do this 3 times. Yeah the transmission fluid is expensive. on the last drain and fill you want to get a bottle of LUBE GUARD from NAPA or who ever sells it. put the whole 10oz bottle in. Shift Rev, 1, 2, 3, D. Neutral Rev D. If that don't work then you have bad seals.
