This tranny was just rebuilt about 3000 miles ago by one of my friends that works at a Pontiac Dealer "he did it in his spare time for $175.00 labor plus whatever parts cost". It has a 3000 Vigilante stall.
About 2 weeks ago the car wouldn't shift into 3rd at WOT unless I let off the gas about halfway. My new motor is drinking about 2 quarts of oil every 7-10 days because it was wayy to rich when it was first put in and has moly rings. Someone advised me to let it get to about 215 degrees and then run the crap out of it and the rings may seal or it's time to pull the motor back out. I'll probably be single if this happens since I've spent way too much on it already and everything has broken since the new motor has been put in.
I do as this person said and flogged it pretty good about 6 or 7 times and on the way back to the house the car was in 3rd gear and just revved up like it was in neutral. Changed the fluid and filter the next day. The tranny pan was very clean and the magnet had barely any metal on it. This made no difference. If you leave it in drive it will shift 1-2 just fine then when it tries to go into 3rd it's just like being in nuetral, if you rev it high enough it will catch 2nd or 1st gear again and if it catches 1st you have to manually shift it to get 2nd gear. I know barely anything about trannsmissions but this almost sounds like there is a leak in the valve body somewhere. I hooked up my laptop with Datamaster, no codes from the tranny and it was building pressure just fine.
Any of you tranny experts out there know where I might start to look for problems at. I have no problem with pulling the valve body off except for the fact that I've never done it before, but I'll certainly give it a try.
