Tested it out in the front yard for a couple minutes and got everything adjusted. We went to the track this morning and he started driving and the clicking noise came back. So we packed up, headed home and tore it apart. Everything looked fine. Put it all back together and the clicking noise was still there. LKS guys say to just scrap the tranny and start fresh. Not an option. I have torn it apart a reassembled it a couple times and the click noise goes away and comes back shortly after it has been running for a while. Any pointers?
