Because it's cheap to use the same transmission. It is borderline, so ok except for tuners.

You get rid of the heat by getting rid of the oil cooler thermostat. Guys who do this and don't tune for higher power don't have issues, in general.
There's a by pass valve in the transmission that when altered to direct flow helped the heat issue, didn't know or think about the thermostat. But once the tranny is figured out I do plan on adding a bit of power. I'll keep tinkering with truck till I can't.

No, this is in the oil line to the cooler radiator in front of the truck. RevMax Transmission Cooler ByPass Housing Installed.jpegRevMax Transmission Thermostat Housing Replacement.jpeg

Here's pictures of the RevMax straight-thru retrofit housing I replaced the OEM thermostat housing with. ATS also makes this housing.

Yes, That thermostat will get plugged with clutch debris and cause the temps to go up and most don't notice until it's too late.

What a blessing to always be able to make it home at least.

And the thermostats aren't reliable, either. Members report being stuck closed. I suppose they're made in China. Add to that the orifice for the thermostat is much smaller than the cooling line, and you have restricted trans oil flow even when the thermostat is open. What a complete Rube Goldberg Kluge of a concept & design!! I spent 32 years in Design Engineering.

I replaced the trans thermostat block with the ats unit and all is well. No issues and notably cooler trans temps.

I should be getting my truck back this week with a new factory reman transmission. Can I tow my travel trailer right away, or is there some sort of break in period before I should tow?

All Hemi cars after a certain year .. (08 I think) had them .. parts are interchangeable between the 45 all the way up to 68RFE with 68 being the biggest
The cars use the Nag1 /W5A580 transmission,not an RFE.Totally differant transmissions.

I think all the break-in stuff is about getting the rear-end set properly and maybe the engine too. I've never heard anything specific to the tranny but you might ask the dealer. Post rebuilds (I've had two done at the dealer) they never said anything.

Do you have a link to this? I’m thinking this will be my next thing to do for the trans. Thanks

These are sold at most automotive supply stores. May be under transmissions or accessories. Just search for ATS or RevMax.
