I'm looking at replacing my original Tranny (3 spd) with, hopefully, a 4 spd model. Anyone know if this requires any special kits? I'm assuming
that my 32/36RH can be swapped with a 42/46RH. Please let me know if this is true.Any info would be great! This'll be a fisrt time do it at home
project.

Thanks,
Andy

I may be selling the 4spd manual off my 83. Im still debating wether I want to replace my 3'spd with it.

He was talking about a manual tyranny??

 

No, he was talking about the Auto, but I have a manual and I may be selling it. Im tryiong to figure how much money I want to put into the 87 I have since I suspect it needs an engine. but that is another topic
