So previous rebuilt apparently broke it's intermediate band, so I took a spare and had it rebuilt.
77 C4, shop built it, added a Fairbanks shift kit and a Boss Hoss convertor. I installed it yesterday and only had 1 and D, either auto or manual, would free rev in 2. Shop is over an hour away so trying to trouble shoot myself. Talked to him some, trying different things. So swapped modulator from previous trans, which gave me 1 and 2, but no drive, would free rev in D. Played around and got it to shift to third, but would flare. Drove for awhile, played with modulator adjustment and lost drive again. Swapped out modulator back to new, still no drive. Checked vacuum, was 10 at shared trans, pcv, and brake booster, ran new dedicated line to front line under carb and have 14 at that point. no change in shifting.
He wants me to either bring him the whole truck, or swap out the valve bodies and mail him mine. Any other clues what I should look at?
