Doug Nash 4+1 Help
I have a Nash trans with Liberty face-tooth gears. Heavy, but bulletproof. However, every once in a while, the thing will not go into 3rd gear going down track. It goes in third around the pits and on the return road but under 8000rpm load it won't. It does it randomly and it did it in 2nd round last night. It is not a clutchless trans and I have to use the clutch to shift so I put more pedal travel (We are at about .080 air gap) and I even tried granny shifting it in 3rd round last night and it still wouldn't go in. We've taken the trans apart a few times now and found nothing.. Everything still looks brand new. No problems going in 2nd or 4th ever.
Could the clutch be getting too hot in the burnout that it is not fully releasing? But why is 2nd and 4th never a problem?
