Author Topic:   Powerglide Cooling - Yes or No?
posted April 20, 2003 12:53 AM
Okay guys,
Building a new I-Stock of an 82 Cutlass. My buddy's powerglide was giving away on him in the feaure tonight. He said the bands were slipping and that a cooler would alleviate the problem. My engine/chassis builder says the cooler is not needed. This is a BIG 3/8 high banked track. What do you think?
Also does anybody here use a slight support under their powerglides? Thanks, Dman

weve been running power glides in our cars for the last 4 yrs and have never run a cooler. We run it direct drive without a converter and we dont use a crossmember either. We also run on a big 3/8 mile and our mains are 30 laps. Hope this helps

I have ran powerglides 4 years, used a tranny cooler my first year and never did again. Never noticed a difference. Start running lines to cool it and you have a chance at something breaking/leaking and then it's just a big mess. I race a 1/2 mile banked dirt track, 12 lap features, for reference.

on direct drives you can pretty much run without a cooler,but with a converter.because of added weight from the converter,alot of heat builds up,so it is really important to have some type of cooler.the extra fluid in the lines helps keep temps down.if you race in a cool(cool evenings,or days) region,a small cooler will do just fine.if you race in a hotter climate,say new mexico,texas,arizona,and like wise,it's not uncommon to see very large coolers,or even condensers being used to keep the tranny cool in the hot for fluid,i have used the regular store dextron that we get from autozone,and it has worked fine.because of the way race glides are built,it's not wise to throw some thick fluid in there,besides it's better to have a fluid that can move through the system quick,tranfering heat away from vital parts.if the tranny is built right,you can get through alot of races before a fluid change.we change around 10-12 races,and the tranny has worked flawlessly.i might add that i use a small oil cooler,and it works great.
