sounds like you should check the fluid to see if its full and is dark brown/black and has a burnt smell to it.

no i changed the fluid last week, i called TCI they said it was my Vacuum Modulator, i guess there is a crew in there that i had to turn a couple times. but its back to normal, thanks for your guys help

yeah those vacuum modulators can make quite a difference in the old th350/400 transmissions. Reminds me I need to make an adjustment on mine. Shifts way to soon on the road turning the 38's.
