I had my 2000 TL auto trans rebuilt recently. It soon began vibrating when shifting from 3rd to 4th; then 2nd to 3rd. But it was very intermittent. It got progressively worse. The Aamco and Acura dealer thought it may be the egar valve but it remained after it was replaced. Aamco did another total rebuild this time using oem honda clutches and they had the factory torque converter rebuilt instead of using and aftermarket one.
Guess what - no change.
HEEEEELLLLLLLLLPPPPPPPPPP. AHHHHHHHHHHHHHHHHH.
Could it be a timing issue or a differential (does this car even have one)?

 

Whats the mileage on your vehicle???

 

88,000

 

What year is your TL,
They have an extended warranty on the transmissions....

 

I did not receive a notification but Acura already reimbursed me for the rebuild bill. I don't think this is a trans. problem.

 

Damn I don't know what to say.

I have seen some TL's get three different tranny in the 7-yr/100,000 mile warranty.

What does client services say about it,

800-382-2238

 

check your rear transmission mount, and the tq converter.....
