hey guys,i have a lockout kit on my tranny[700r4]90 so the OD doesnt kick in until I want it . Its set at 50. always worked perfect{the tranny] recently basically overnight, when I got to 50 and my OD kicked in I got a heavy vibe,when i keep the same speed and maually put into D it works fine [no vibe] until i have to increase power [such as an incline on the highway] more peddle -vibes start to come back,but not as bad as OD.Its not mounts or ujoints -already checked -and i can get to 70 on flat highway in D without the vibe. any one have any exp w this? could it be my TC? thanks for any input.

I had this happen, but only after I replaced the TC. Not sure why it happened, still does it... Does it have so much vibe that it doesn't accelerate? My 87 S10 did that. It sould get a bad vibe and wouldn't accelerate, let off the gas and punch it and it would go away...most of the time. Ended up being the TC coming apart internally and it screwed the trans.
Same thing is up with my 90 I have the tranny out just waitin on a new T/c to get here.
