Transmission Cooling System

[Joshua.O.Brown7]

I'm gonna do a running transmission cooling system. Most likely a Hayden 678 Cooler with Improved Racing thermostat. Which would you run?

High-Flow Engine Oil Cooler Thermostat, 215F


High-Flow Engine Oil Cooler Thermostat, 185F


High-Flow Engine Oil Cooler Thermostat, 165F


High-Flow Engine Oil Cooler Thermostat, 145F (Picture found same as 165F)
​

Features and Benefits



Reduces excessive engine wear and horsepower losses while improving gas mileage by preventing oil temperatures from dropping below optimal levels
Maintains a minimum fluid temperature of 215°F (102°C) +/- 5°F in most conditions
Patent-pending, high flow, low pressure drop design locates the valve assembly completely out of the primary fluid flow
Allows a small percentage (less than 10%) of fluid to continually circulate through the cooler to eliminate air pockets and prevent cold fluid trapped in the cooler from shocking the system
Rebuildable
6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
Lightweight at just 12.7 ounces (360g) without brackets or fittings

Applications
The FSM series thermostat is designed for universal oil temperature control in engines, transmissions, differentials, and industrial cooling applications.

Includes
1x 215°F Remote thermostat block
4x Black anodized 3/8" hose barb or -06AN, -08AN, -10AN, or -12AN adapter fittings with Viton O-rings (OPTIONAL)
2x Zinc-plated steel mounting brackets and screws​

Or do I just opt for the Hayden 163, yes it's cheaper but why not try to do it right?

I vote nothing, no need for this. Put the money into something more useful.

I've never seen this product before, it looks really cool. I would go for the 185 because that's the upper temp range you want to operate at before doing any serious cooling.

I'm not entirely sure if a thermostat is necessary, though? I mean, the B&M 70268 cooler has viscosity ports to regulate cold/hot fluid built in. If that's not enough you can wire in a small fan with a thermo-switch to engage at that same degree.

Yea none of that I'd use the B&M

The B&M 70264 has a LPD already built into it, beginning to open at 170 and fully opening by 185 or maybe even 180.

Take your savings and add a spin on ATF filter in the mix as well.

The tranny is that temp sensitive. Just buy a b&m and run it.
