Mouse, you think rebuild the thing will solve the problem ? what is rebuild gearbox anyway ...[/quote]
bro, rebuilding a unit its like a recond unit (but using your own gearbox instead of a recond from other cars) but the quality of recond unit nowadays is not good coz they will open up the whole gearbox and only change the parts that they think its necessary, other part if they think is still ok they will not change it (save cost). hence, after u buy and recond unit and u trade in your own gearbox, they will do the same with your gearbox and sell to others like they sell to u. by right, when rebuilding either your own gearbox or a recond gearbox, they should change all the parts inside the gearbox no matter if they think if the parts is still usable. this will asure after rebuilding your gear box if not 100% like new also will be 80-90% new. but i am not very sure if they have a complete overhaul kit for your gearbox.
