I'm Running a powerglide in a camero and it seems to be very hot(250-300 F)after each race. I have to run a converter, so I had a low stall one built at the local tranny shop (they specialize in this. I'm running the biggest trans cooler they make. I only run it in first gear, I've tried dextron II and TypeF, the band is red hi-po and is adjusted correctly. I'm concerned about cooking the tranny and would like some Ideas on a solution. Oh its about 400HP and 6500rpm, 3/8 mile track with generally tacky conditions,275/60/15 tires

Thanks Guys

That is on the warm side but not overly hot. I would check pressure. Take the plug out of the low gear servo cover (the cover with the 3 bolts on the right side) and put a gage in there (200psi capacity, I use a grease gun hose on it so I can turn it to read it) now put it in low and bring rpm up to 1500 or so and pressure should be minimum 110-120 psi 150-170 is better but requires a high pressure spring. The major cause of heat is slippage. If pressure is under 110 at 2000 rpm its time for a refresh.

r&o hydrolic fluid will work better than trans fluid doesnt foam as bad and does make it cooler i would also s**** the stall converter and run a vega converter

Summit deep cast aluminum pan (+2 qts I believe). It helped drop mine about 20 degrees. I also use 2 smaller (I think 6" x12" x .75") B&M coolers in series. Use to peg 280+ after 10 laps with the stock pan and 1 cooler. Pan brought it down so it would at least stay on the gauge by the end of the race (15 laps) and the 2nd cooler brought it down under 240 no matter how long the race is.

And the best convertors to run are the TCI circletrack units.

Vega convertor will add heat and slip as well under that many ponys.I put one on a 350 at about 375 horse and hated it.Got a big 383 now and a b&m convertor fells like a kick in the pants off the corner if the track is tacky.
