Thanks Doug and Rob it was great talking with you guys
While driving home 3rd gear starting slipping while pulling a hill, checked it on the computer with my son the next day to confirm.
Pulled the trans and tore it apart. Check everything. air checked the pistons (all ok) air checked from pump (partly assembled a lot of air leaking from the shaft) and finally found 2 teflon seals cut in 1/2 at the pump shaft (the builder cut them for easy install) Going to replace the converter from a low stall 1200 rpm to 2200 rpm to get rid of my stalling issues when putting into gear. I'll post pics later. Rich
