Ok, Ive searched and found tons of arguments about this. I have a 700R4 right now but it only has reverse left. Now lets say i Get a TH350............ WHAT EXACTLY DO I NEED TO DO TO MAKE IT FIT!.

My car is an 84Z. Thanks guys.

 

Youve got a few options. Since no TH-350s have provisions the torque arm and different mount locations then the TH-700R4, youll need to get a new crossmember and torque arm. I recommend a Spohn unit to make things simple. Also, B&M makes a kit, but I have no idea what it entails. Im not sure if and what needs to be done concerning the computer.
