you'll have to change over the torque arm mount.. and the gov... so your shift point will be right... im guess this is a 2 wheel drive

Re: trans bad?
maybe I missed it but what year and powertrain is your car? I can tell you the pump, TC, speedos and tailshaft is different. You're better off buying a used unit from a similar app & year.

Re: trans bad?
you have to totally gut the trans and get donor parts from a good tranny your better off selling it and getting one from a camaro or firebird if u can find one.. you'll have more money in getting the work done and gettin donor parts... than its worth... sorry man
