very cool offer Heath....check it out. I went to see a trans shop about 20mi away, so he could see what I was lamely trying to explain to him, and by the time I got there he had one waiting on the counter....so yeah a 4L80 unit will work. I was ready to build a spacer to put under this roller clutch to raise it up enough to engage the center support race.
The old roller clutch on the right, the newer style on the left:
The old style reaction carrier (70's's era, but also shared with 4L80's) notice the flat bottom and sides, this unit requires a spacer (which is hard to find but was factory in some models) to keep the roller clutch up to engage the center support.
The newer (or maybe older, 80's era) notice the beveled side/bottom that keeps the roller clutch up higher in the drum, making contact with the center support race.
The old reaction carrier surface (where the band has to grab) This isn't too bad to be used in a car, where light loads are encountered in reverse, but for offroading he suggested it be replaced, and thus started the seek and find mission of today.....
The trans is bolted to the engine once again
Heath, I'll keep your trans in mind if needed....I thought about pulling the one out of the Vette if I need it too.....but would have to tear down and replace the output to match the 203 doubler setup.
Lets just hope this one works this time.
Grabbing some dinner right now, then headed out to get the doubler put in. Hopefully a test drive yet tonight.
