Hello There

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.

It appears you have a Forward Clutch FAILURE. Replace the trans after you get it diagnosed and verified by a professional technician. By the way, do you have a Check Engine light? If so, what is the diagnostic code? The dealership can scan the system and find any codes which may have been stored in the TCM (Transmission Control Module). If there were any 'Incorrect Gear Ratio" codes, it's most probably the trans itself.

Nope. There is a drain plug on the transmission case. It is a simple drain and fill. Odyssey transmissions do not have a filter.
