Transmission coolers.

Who knows anyhing about the correct size of aftermarket cooler to run for a tranny.  '77 k10, 383 stroker w/ a 350 tranny.  Right now I have a cooler from "Derale".  They claim it is for a 4x4 up to 20,500 gvwr.  But, the cooler just doesn't look like much.  I have it running in-line with the "stock" radiator cooler now.  I would prefer not to do this.  I blew my last tranny when the radiator blew a seam.  I kept enough coolant to cool the engine, but, not the tranny.  Thanks.

Here's the one that I run: Tranny Cooler

I have had absoultly no problems with it what so ever.  I use my truck to plow snow with so you know that it has to heat the tranny up alot.  Also if you are concerned about tranny temps I would suggest installing a temperature gauge on it.

I run my coolers independent of the radiator.  The rule w/ tranny coolers is run the biggest one you can fit and if you can't fit one big one, see if you can fit a couple small ones.
