Ain’t no feeling like Oldsmobling!
A few months ago I started a thread on a th400 that goes to nuetral at WOT. I rebuilt another core, out of a 69 442. New Raybestos GPX frictions in the forward clutch, Sonnax clutch hub with bearing, new 34 element sprag, bushings, thrust washers, roller clutch, bands, etc. Took the car out for a test drive, worked flawlessly for the first 10 miles or so. Did a couple 30mph WOT, once again, felt great. Came up to a stop sign, felt a clunk, now it won’t move in any forward gear, and binds and chatters in reverse. Takes a lot of throttle to get it to move in reverse, it will roll easily forward. Obviously, it needs to come back out. Any ideas or thoughts on what might have broke? Thanks
