Hello guys.
I got the MM3 installed, and at the same time, I did the Revmax valve body and cooler bypass, now the transmission is running hotter than before.
210-215 in a cool day (70) driving empty, before the transmission was running around 170-180, any idea what is causing this?
Something is def going on.
When not towing, my trans stays very cool, 165* at highest.

That's what I am trying to figure out.
Revmax valve body, OEM filter, Revmax cooler bypass, and MM3 tune by Ray at @DRD transmission was not doing that before not sure what was going on.
The top line in the bypass is really hot; the line is cool to the touch.
Have you tried to contact Revmax?

Yup, pretty much the same mods for me.
How many miles before you put VB in?

The transmission has been new since I got it rebuilt.
I would say 2000 miles.
Oh yeah, something def, not right.

Hopefully, Mike will have some suggestions after he talks to Revmax tomorrow.
You said the top line on the bypass is hot as you would expect since this line is coming from the transmission.
If that line is hot on both in and out to the cooler, then we know you are getting supply flow through the input of the bypass.
I wonder if, for some reason, you may not get good return flow through the cooler and bypass back to the transmission.
I was thinking out loud.
I was trying to find an easy way to verify system flow without disconnecting the return line, losing transmission fluid, and making a big mess.
Maybe use an infrared temperature probe to track the temperature changes through the cooler to the bypass.
Also, If the cooler and bypass are working correctly, I would expect the transmission pan temperature would be lower than the temperature of the top line on the bypass going to the cooler.
