Re: 4 speed conversion HELP

I figured it out but have not fixed till this weekend

the m20 would not go the last 1/8 inch into the bell housing
I pulled it apart put trans and bell housing on bench bell housing was too small by a tiny bit
I believe this is because I bought the cheapest gm bell housing out there. AKA China CRAP
I hogged out the hole until the trans fit It was not precise surgery as the bell housing / trans mating area is thick

So I have a not correctly aligned issue not going in a perfectly straight line messed up the clutch trans working.
The problem is I need to get a Summit or Jegs bell housing and test fit on the bench for correct mating install.
This should solve the problem

That being said when it ran and engaged for fifty miles the 4 speed roared with the 373:1 rear gears
did not plan on that. The old trans was a 700r4 with single wire overdrive worked great for revs with the 373:1
So the plan is to sell the m20 shifter and rods on e bay and go with a T5 which leads to my new post
Has anyone done this b4 looks tricky to get the system right see you in the next POST
THANKS
