my automatic tranny is shifting sparatically and its driving me insane. ill be going the same speed, and it will downshift out of nowhere, then upshift constantly. it dosent shift very easily, seems to get stuck in nuetral. also, when it is cold, it takes about 45 seconds to shift into drive, then when its warm, it takes about 5-10 seconds for it to shift from park to drive. I have a 1989 chevy suburban v2500. i put a turbo hydramatic 400 tranny in it, and this will have been my second rebuild. the modulater is in working conditions, and im pretty sure the vacuum is working, more testing is required. tranny fluid is clean, but i have yet to check the magnet in then tranny pan. the level of fluid was constantly monitered due to its rebuild. its only 2 years old, and ive already rebuilt it before. any diagnostic tips would work wonders for me. i would also like a link to a troubleshooting chart if anyone knows where one exists.
