i have an issue with my trans after rebuilding it due to delayed shifting i put a stage 2 shift kit in it and changed the clutches the issue im having is randomly it feels like it going into nuetral almost like poping out of gear at first after rebuild no issues and i took it out one day and the torque converter seal started leaking fixed that and then came this issue when it doesnt act up it shifts really good hard and fast but just randomly it does act up any suggestions or things i should check it does have the cooler on the radiotor but its a 4 row radiator thanks
