I recently installed a full trick flow top end kit on my 87 notch with AOD. It runs great with the exception of bucking at low rpm (usually 2000rpm or less while coming to a stop) while in drive. It sounds like it clunks right at transmission and drive shaft as well. I noticed that this doesn't happen if I pull the car into first and decelerate that way. I am used to it and can drive it in a way that doesn't bother me but I am thinking about selling my car for another project and want it to be bug free to the next owner. Any help would be great. Thanks all.
