I recently did a rebuild ("ground up") on my 88. New 4 bolt main, 383 stroker.
The car turned into a rocket, but the 4+3 tranny gave out. I had the tranmission and overdrive units rebuilt, but shifting the unit has never been right since. The shift linkage was reset correctly but that didn't help. We began to think the clutch was acting up, and discovered a clutch master leak. The clutch master and slave were replaced and bled properly (including "tilting" the slave to 45 degrees to get all of the air out) but it still had trouble shifting into reverse and first.
I saw an article somewhere about the reverse lock-out rod being worn, and when I took it out it really was worn badly. I contacted Chris Petris in Florida about a new rod and when it came I thought this was finally it. It didn't help at all.
When it is cold (which is rare in Phoenix) it does shift more easily, but after about 10 minutes if I come to a dead stop and try to shift into first it must be "forced" in with much more than normal pressure. Once I stop I cannot shift into reverse without at least some "grinding" and this is beginning to drive me nuts.
I suppose the rebuild of the tranny could have been done improperly with the syncro's not working right, but the guy who did the rebuild has done hundred's of these things.
I bought "101 projects for late model Corvettes" (or something like that) and it has a long article on properly adjusting the linkage. I plan on doing that next week, but I have my doubts that it is going to work.
Anyone got any ideas?
Thanks,
Mike
