Engine/Transmission (1994 - 1998) Flushing transmission coolers

[Hummin Cummins]

I should be getting my new GB transmission in a few days. I need to flush the coolers to get any junk from my wasted t/c out of them. What is the best way to do this? Can it be done or should I replace them?

Flushing

Get a trans cooler flush kit from NAPA. It comes with an aerosol can full of some sort of solvent and hose/adapter to make the flushing of the trans cooler possible. Be sure to flush all of the lines going to and from the cooler also.

trans coolers

My personal opinion is to replace any cooler that was in the system during a failure. I worked as a mechanic at a caterpillar dealer and ANYTIME a trans failed, we replaced the cooler. Too many places for debris to hide and is cheap (relatively) insurance for the longevity of the new trans. I know some people trust the cleaning system you can buy, but... ...

Update

I just talked to Dave at Goerend Bros.

He told me there are 2 coolers in the crate with my new transmission.

Now thats service.

Well, there you go. I'll be checking them out when I go for trans upgrade parts.
