today i did a complete trans flush to my car. it removes between 99-100% of the fluid in the trans, including the converter. i used B&M trickshift fluid. its blue in color and claims to raise the stall speed a little and defintly firm up the shifts. it took 19 qts of fluid to get it running clear blue out of the waist oil line to our machine. i cant wait to see how it affects my launches
for anyone with any miles at all on their car, i recommend having the trans flushed, not just a filter change. our filter it just a nylon screen. this machine back flushes it and gets all the crap out of your trans. and it flushes everything, coolers, converter, valvebody,filter,lines, EVERYTHING

well i got the fluid at cost and bought 20 qts. and it didnt cost me a thing to use our motorvac trans flush system at work, so i have 60 bux in the whole deal

well i work there , and im the only one that uses the equip.[ only mechanical tech in the shop ]
im hoping it raises my stall like they claim

B&M trickshift is not a synthetic fluid. it is a HP trans fluid. now they do make a synthetic fluid, but its like 9 bux a qt

mine is working smoooth. shifts are defintly firmer, plus it has a high pressure feature to add the bushing, bearings , and diff wear under extreme loads
