Hello all, just finished a rebuild (motor and trans) on my 89 GT and aside from the usual minor bugs to work through I have come across one problem I'd rather not dive into until I had some feedback from you folks out there. The problem I'm having is with the trans., an AoD (yes yes i know "go get a stick") which is actually working great and is alot of fun aside from the fact that it doesn't want to downshift itself under deceleration. All gears work great and will downshift perfectly if I do it manually but if its in D or OD it hangs until the rpm bogs down and will then release. Its not just one gear in particular its all of em (can feel the separate lagged downshifts out of 4th and 3rd, 2nd as well but it doesn't bog near as bad) and is only under deceleration, kickdown function works great. After some research I was thinking maybe a governor problem which would make sense as its the only old part still in the stinkin thing (I did clean it all out of course) but didn't want to tear it out w/out some input. Should probably mention along with new parts a transgo reprogramming kit was installed (did not opt for the high rev gov. for over 5k shifts as my motor is mostly stock except roller rockers and a few other things) Thanks for any help offered up in advance I know I've learned alot from you guys already just as a lurker
