BorgWarner 35 trans with around 45k mi. Pulled pan and everything looked like new. Installed tranny in a '63 series III. A short road test seemed ok, after about 100 highway miles the trans extremely overheated and spewed fluid all over the road and parking lot.
Back on the bench (couldn't find anyone locally willing to look at it) Couldn't find any major areas where the fluid escaped. There was light debris in the pan and aluminum film inside the torque converter - sent the converter to be rebuilt (rebuilder said needed parts).
Got a major rebuild kit. Took everything apart, all the seals & clutch plates looked like new but I changed them anyway. The only thing noticeable was the spring plate in the front clutch was broken in 4 places. Rebuilt and adjusted the front & rear servos and kichdown cable to book specs.
After installation the car will move on a level surface but couldn't even pull itself up my steep driveway in D1, D2 or reverse. It acts like standing on the brakes while giving gas in gear. The engine bogs down and the car won't move. The brakes are adjusted and the car drifts out of gear.
Took everything back apart and the only thing found was the sprague (one way) clutch which did work one-way on rebuild now spins both ways (on order).
WSM 139 and other BW35 manuals give great info. but I'm totally dumbfounded as what to do.
I welcome any and all suggestions and comments.
