Every year I've had to rebuild my trans, some of my mistakes, some bad guidance. First time I bought a TCI kit, and TCI shift kit, with a hardened stator support, and upgraded sunshell, larger pressure valves. The frictions and steels didn't look to bad, except lo/reverse. When I put it together my guidance coudn't find clutch clearance specs, and told me It worked before, should work now, so we left them like they came. It shift well, not real harsh 1-2., a little harsh at wot, except for the common 2-3 flare, shifted good up at the track, I like to shift manually and except for the flare I was happy. After reading in here about the problem, I figured to take it apart, dual feed it. The lo/reverse clutch pack clearance was wide .125"+, I asked and was told by the board that wouldn't be a problem. Chris's book and his shift kit, and a forward drum, it went together real nice. Pressures where all about 250ish with full tv pressure. Reverse was sluggish, had to rev abit to get it to back up, drove around town shifted nice, I'm running the stiff springs in the accumulators. Went to the track, it shifted from 1-2 at 4500 all by it self with the shifter in low, but every thing else worked ok. Checked the shift linkage it's good. I figured I try the old shift kit in it this year and try for the best of both, when I drained the fluid it's very dark, but red and it doesn't smell burned. Get it back together with new fluid, no reverse and now it creeps forward in reverse, I figure I lost lo/reverse again, this was while it was on stands. Checked pressures 150ish, doesn't seem like it down shifts to 1st now. I'm going to try Chris's shift kit before I take it out. This is a 87 tranny out of Gran National, BQF code I think. My biggest question, With dirty fluid do you think that crud be causing my low pressure problems, crud in the pressure regulating valves. evey time I drop it on the ground it has good pressure, next spring it doesn't? This is in a 67 Camaro with 400hp sb on a good day. Any thoughts, comments? I'm not blaming Chris, he didnt build it, I did, I'm no tranny guy , but i've built plenty of engines, and thousands of Diesel fuel pumps which have the tightest clearences of any thing I've seen, Millonths of an inch. Thing that gets me the most is the shifting, 1-2 with out moving the lever out of manual 1st. Ron
