Ok i'm looking to do some light towing, and offroading with my 98 4wd blazer. I'm looking to add an aftermarket transmission cooler to it and i was looking and was wondering where you guys are mounting them? I couldn't see many spots except for maybe behind the grill?
Any ideas and possibly specific coolers you guys run would be helpful. looking to do it as soon as possible. i just want to get the right cooler that will fit.

 

This is a topic that has been discussed in the past in great detail. A search for "trans+cooler" should bring up the pertinent threads.

Hayden and B&M used to be pretty much indistinguishable. However, B&M has since altered there design to add a viscosity bypass region to the cooler. This diminishes over cooling so you can plumb the cooler in on either side of the stock, in radiator cooler. I recommend the largest (within reason) B&M SuperCooler you can buy.
