Bypass radiotor instead of replacing?

The manual 4 runners don't need a trans cooler..(

My manual trans Camry with Celica GT4 drivetrain has a transmission cooler! (it has an oil pump, cooling loop and squirters for the synchros - all OEM Toyota)

So, not *all* manual transmissions have no oil cooler :smokin:

That's interesting. Is it a mechanical pump? I looked up R series transmission coolers and many seem to use an electric pump.

Correct some do..Hence why I stated manual 4 runner 3rd gens..

Wouldn't your Camry and Celica have trans axles too which would be a transmission and differential combinations.

I was never fortunate enough to have a standard camry. I have however had an engine and transmission out of a 90 Camry swapped and done with using a tree in the yard.. However it was an auto.

Yeah, mechanical gerotor style driven off the center differential. It only pumps while the car is moving.

Yeah, transaxle - with 5 forward gears, two differentials (front and center), rear angle drive *and* a viscous coupling unit all sharing the same lube. Lots of heat as manual transmission go, and it was a rally homologation drivetrain, so lots of extra 'bits' are included that wouldn't normally be needed on a street car.

It would have to be with all that going on. Its more of a hybrid fluid with one cooling system then separate components

The 2 downsides i see from this type of setup is:

1) contamination destroys everything

2) more seals more chances of developing a leak and with a system like that.
