Im looking to improve the stock transmission oil cooling. Since the factory routing runs through the coolant radiator and then through an oil radiator, these are the 3 methods im considering.


1. Replace the factory oil radiator with a larger one.
2. Eliminate running it through the coolant radiator and instead run 2 oil radiators
3. Add a fan to the factory oil radiator

Has anyone done any of these, and what were your results?

 

I also see some plastics covering the lower half of the factory oil radiator. Would it be a good idea to cut some material off to expose the cooler more?

My tow load isnt too much about 2500 lbs and 4 adults, but with lots of inclines and for long periods (Big Bear mountains in CA) in 95+ degree outside temps

 

my son has a 94 , bought with rebuilt tranny,23000 on build,when he bought it, lines disconnected at radiator, only go thrue good size cooler, engine temp guage stays below norm, don't know what tranny temp is, need separate gauge, thought engine temp guage was supposed to be like an idiot light?
