Have you noticed how hot these transmissions run? Typically around 200degs in traffic or hotter. Mine runs about 187deg during a long trip down the hiway. Last trip was to Laredo, averaged about 185degs back and forth.
When they first came out, we stuck a couple BM coolers between the radiator and ac condensor. We noticed a huge drop in transmission temperature.
We also bypassed the transmission cooler embedded in the radiator.

After the installation, we've noticed 130-140degs transmission temps on the highway and most of the racers can now hotlap their trucks non stop with no heat issues.
One customer just reported his trans temps won't get above 180degs after 15 consecutive laps down the track.

The trans temp will get even hotter after a higher stall converter is added.

I realized trans temps need to be brought up to operating temps, but we haven't seen any negative effects after making them run a lot cooler.

Just an fyi, later,
