I have always ran a cooler in the past. Heat is the #1 killer of an automatic transmission. Depending on what you have , you are most likely fine with one from the parts store. I personally use the biggest one I can fit. Some people use the zip tie style of fastener that goes through the fins of the cooler and then the fins of the radiator.I guess its ok, but I just don't feel comfortable going through the fins of either. I usually fab up some kind of bracket with a rubber covered clamp that goes around the tubes on the end. The big thing to remember is to use transmission cooler hose instead of rubber fuel line. There is a difference.

Re: Trans cooler

Agree n trans cooler hose vice fuel line hose.
Added cooler inlet shuld be from upper radiator cooler fitting, as GM fills from the bottom up, and new cooler should also be plumbed the same, fill from bottom up as this effort removes air from cooler.
then tie cooler outlet to trans return oil line as this will put cooler after radiator cooler -> trans -> radiator -> new cooler -> trans.

Re: Trans cooler

and....use AN style fittings vs. hose clamps if its in the budget. It just makes for a better looking and more reliable system.

Re: Trans cooler

I don't want to attach it to the radiator. What is the best way to mount the cooler?

Re: Trans cooler

Its easy enough to fab up something for you system. Go to the local Home Depot or Lowes, get some light gauge metal, measure, drill, bolt, ETC and you're done....maybe even paint it to make it look professional ?

As for the trans and install the biggest one that will fit. Never heard of anyone over cooling a trans.

Re: Trans cooler

I recommend the biggest cooler you can find (motor home is a good start), then plumb it through the radiator cooling reservoir to maintain proper fluid temp (not to hot, not too cold, the thermostat in your coolant system keeps it just right!).

I fab my own brackets and use AN-8 hose and fittings.
