I am attempting to swap the 4t60e from my bonneville to my park avenue. The Buick'* case in broken just before the differential housing and I just rebuilt the one from the bonneville.
The harness under the valve body pan have different color wires and the buick has a temp sensor that the bonneville did not.
I am hoping/wanting to swap the buick valve body to the pontiac transmission in the hopes that the ECM will think the trans is the same one.
Will this work?
Any tips tricks thoughts on this?
I have never rebuilt a transmission before but I am too broke to pay someone to do it for me and I also have always wanted to know how so I jumped in with both feet and now I am done except for the valve body. I have the rebuild kit and don't know which valve body to put it into.
Thanks in advance.
