hello there I am new to this forum and I am getting ready to install my PA C4 transmission into my 1989 Notchback. I recently removed the T5 transmission. I can keep you posted on what it takes. this will be my first time doing this kind of swap. So far everything looks like it will be a simple install.
everything will work.the only thing you will have to change is the shifter.you will have to get a converter with 11.4 bolt pattern.hughes makes a converter that will work with your aod flexplate.make shure the c-4 has the big bellhousing.any questions feel free to ask.
