Had a new Raptor 200-R4 trans installed awhile back, with a Pats 2800 stall converter. Maybe it's me, but it does not seem to hook up. Do I really need to get the engine up to 2800RPM before I get hook-up? It feels like it's slipping at low RPM. I also have a leak around the TCC connector, any tricks to stop the leak without dropping the pan......again?
