Re: 700R4 back to a 3 speed

All good.

He already rebuilt the dash and changed out the polarizers. Wasn't to bad since he did it himself. It looks really nice. I think it is a crossfire injection car.
He bought it with a bad trans that seemed a lot like a TV set up wrong. The TV was stuck. Got it unstuck and the 3-4 was dead. He pulled it and him and the transmission specialist at his shop went through it, but TV still didn't seem like it would set right and the 3-4 pack went again. They pulled it down again and the same person, who has an excellent reputation on these transmissions, went over it very closely trying to figure out what happened. They could not find any smoking gun, other than the bad clutches, of course. They built it back up but installed a kit to open up oil flow to the 3-4 pack. He has driven it for about 6 months commuting a pretty good distance for work and made several trips in it. It has felt ok to him, but not given him confidence. It dropped the 3-4 the other day on his way home from work (where he just put in notice so he can focus on his classes), he dropped to second and it was gone by the time he got home.

I think he is done trying to build this trans. There seems to be something wrong that is difficult to diagnose and he is a bit worn out with it. That is the reason I offered mine. At least it is known good. Not something he is going to be pulling in 6 months. That is one of the reasons he was really leaning towards a manual swap in the vette. He swapped a T5 for the 700r4 in his 88 camaro when he was 16, so he is pretty savvy on what it takes to do the swap and how much time/money that is involved in it, plus he was around the performance/restoration shop I worked in when he was a kid and has seen a lot of them done. My thought was just the truck is already such a bad hack job, and the vette is still pretty stock. why not use this as a chance to clean up a vehicle instead of having two chop jobs (even though I know he will do a much better job than the truck). I am wondering if the TV linkage in the vette trans has a different internal linkage for a different throw off of the throttle body or something like this. I thought I remember hearing something like that back when I was working on those.

I am actually having a lot more trouble finding a T5 than I used to. We have a spare one in the shop but it is later camaro so it has the Ford trans to belhousing pattern, but I think it is WC. Too bad it is not an S10 trans with the Ford pattern. I could just make my spacer plate also act as an adapter plate . There is always using the camaro bellhousing and fabricate a clutch throwout. Then I would have to use a s10 tailhousing and still use the funky kiltered Camaro shifter.

At the moment I will just keep my eye out for an early S10. If I could find a column and keep from hacking the floor in the truck I would still consider throwing a three speed in it for the moment since I already have it in the garage.
