I'm a newby here, I like the site been here many times just never posted. I have a 75 GMC 4x4 33'' tires, 383 stroker putting out 500 hp and a 2500 stall. I have a TH350 trans. I'm setting it up for truck pulling. My truck came with a TH350 trans and I thought I'd give it a try with the whole deal with the rotating mass robbing horsepower on a s.b.c. It would slip inbetween 2-3 gears. I bought a TCI rebuild kit for my trans. I disassembled it but then needed a couple special tools. I took it to a guy who has "30" years of experence. Well transmission will be pulled for the third time. You can't tell when it shifts, no power what so ever. I can't remember the exactly what the guy also replaced beside the rebuild kit I wanna say modulator valve, boost regulator, Transpro shift kit (had one in it before) and a couple other things that I dont remember. He pulled the trans apart says everything is correct. The torque converter isn't being pulled out of the oil pump. Vaccum line are free flowing, no kinks in it. Fluid is at the full mark. Didn't get trans to operating temp because its not correct. Torque converter bad ( brand new too), Any other ideas?
