So I had my trans (48RE) rebuilt by a local outfit in December. $4500, 12 month/12,000 mile warranty. Triple disc converter, Billet input shaft. Supposed to have a TransGo shift kit. Trans lasted three days before I realized it was leaving numerous puddles. Found a few fasteners loose, no big deal. 100 miles after the rebuild the torque converter seized up super tight. Had it towed back, (my dime) and they replaced the converter. 1600 miles into the fresh trans I got tired of the 2-1 gear bind every time I stopped, and the off-throttle 2-3 upshift gear bind, so I took it back. Now the trans shifts SUPER soft, like luxury car soft. And guess what, when I get on it hard, something is slipping. When driving old man slow, (my normal driving style) it shifts into 2nd about 12-18mph, 3rd about 25?, 4th about 35, and lock up happens at 50 on the nose.
Working on it today, I found two pan bolts stripped out and missing, the driveline witness marks were not clocked, and the pan is dripping. They stripped out the bolts for the converter inspection cover, and ran self-tappers into it, which are also stripped. Last week I put a 30HP MPG tuner from Rob Dugan on it, and now the slipping is gone, the shifts are firm and decisive, but the 2-1 gear bind is back. It shifts mostly like it did when I initially picked it up from the trans shop, making me think he messed with the computer (dropped the operating pressure??) to fix the gear bind.
So should I bother going back to him? I really don't want more stripped out bolts. I would fix it myself, but not really sure where to start. What options do I have? Thanks for reading!
