Well not sure about the pressure. In the Fourth round the trans temp was at 180 (no problem rollin forward), put the blower to it and got it down to 150. The next round went in, hit the button and it rolled til I put the brakes on. Dont have to tell ya what happened (was dead late cause i was racing a car almost 2 seconds slower) anyway ran it all out and was 03 slower in et and 02 slower in 60. When coming back up the return road trans was 210 (1/8 mile track). The converter was only used about 2 or 3 weekends last year with the same engine / trans combo in my buddies digger. He thought his trans temp got a litte warm with that converter but it was never ran back to back like the other night. Were changin the converter tonight to a tried and true piece. We are also goin to check the ground on the solenoid. BTW I'm using a SLE with the rpms set about 1700. ANY IDEAS???
