Dan Dishon's Transmission Den / trans fluid?

« on: October 22, 2017, 05:41:28 AM »

Using dextron VI fluid and having good service. Would ATI 20wt. be more stable with viscosity at temps in the 180* to 200* range.This is p-g with cooler.I bracket race, looking for repeatable proformance.

Dan Dishon's Transmission Den / PG transbrake release

« on: July 15, 2017, 03:32:04 AM »

Transbrake release gets slow as trans heats up. The pattern is .007 rt 040 rt .080 rt. At first I thought it was me.Adding air in tires,changing 2 step all make small improvement,but pattern remains.New BTE valve body[not pro brake].I am using dexron VI synthetic.The dragster prints time slips the first two runs,but will loose .02-.03 in 330ft on third run.Trans temp at 150* on all runs.What going on?

Dan Dishon's Transmission Den / P-G rebuild

« on: August 31, 2016, 04:23:41 PM »

I rebuild my P-G,I replaced reverse frictions with good parts from TSR.Old frictions looked like new,but transbrake would not hold  above 3500 rpm.When setting clutch pac went from .085 [tsr settting] to .070 BTE setting [new brake]. went  from ATI 20wt fluid to dextron full synthetic.I have lost .06 to .08 in et. Trans works great,brake holds at 5000 stall,but I am slower.Is the rear clutch pac to tight or is it the fluid?
