th700r shifting problems
i have a 84 firebird with a 2.8 in it. i just finished a rebuild on the engine that did away with all the computer controls on the carb and distributor. I changed alot of things on the motor, cam, timing chain, lifters, rockers, intake carb distributor and some other minor things. all the parts i used were high performance parts that i order from jegs specificly for this motor, the motor runs great now and seems to have tons of power but the tranny wont let it show through.
when taking of it will launch for a split sec then shift and the rpms will stay around 3,000 even though my foot is to the floor. They will climb but very slowly and it seems the tranny cant pick a gear. this trany had a rebuild on it less the 2000 miles ago. I tried adjusting the tvs cable since it is now located on the drivers side instead of the passengers, this didnt do much if anything.
I have been told it could be any number of things but cant determine which one it realy is. Ive been told the cam isnt giving the tranny enough vaccum to operate corectly. ive been told that the tvs cable is making it do this. ive been told that the tranny is run by the computer in the car wich is no longer controlling the car, as far as i no my t ranny isnt electricly operated but i may be wrong , it is a stock 84 th700r and the last thing ive been told is the the tranny is just NFG and needs to be junked and a 5 speed put in.
sorry for such a long post and any help on this is greatly appreciated as i am lost with this one guys. the car sounds mean and i want to prove it .
