Universal trans coolers.
Finally got my trans back today from being rebuilt for my 87, took over a month to get back. I was advised to run an external trans cooler, what's the biggest one I can get away with? Would this suffice?

Re: Universal trans coolers.
Most are rated by GVW. I installed one large enough to cover half the radiator. Basically from the center hood bracket all the way to the radiator end. I used SS braided hoses and AN fittings.

Re: Universal trans coolers.

Re: Universal trans coolers.
I live in a hot climate area, Texas. The more cooling the better. In the winter, yes, I can tell trans temps takes a few miles to warm the oil. The trans shifts harder in cold weather until oil temps are up. I drive slower in cooler weather so oil has time to heat up. If I remember correctly, mine is rated for 24,000 lbs GVW. Mine is routed inline with the radiator cooler.

Re: Universal trans coolers.
Use your Original Radiator cooler as well. Plumb the extra cooler after the radiator in your flow path.

Re: Universal trans coolers.
x2^^^hook up your cooler after the factory one. i'm running a 30 000 lb B&M cooler on my crew, & if you want a few more degrees cooler & easier oil changes, pick up a Derale cooling tranny pan. the extra cooling & capacity is nice, but not getting an ATF bath really makes it worthwhile

Re: Universal trans coolers.
I installed a Tru-Cool LPD (low pressure drop) cooler after building my 700.
I went with this one: http://www.transmissioncoolers.us/4589.html Fit nicely on one side of the radiator. Used their engine oil cooler version on the other side. |

Re: Universal trans coolers.

Re: Universal trans coolers.
Probably not worth mentioning but I will anyway.
Be sure both factory and aftermarket trans coolers fluid flow is bottom to top not top to bottom.
