2016 Ram 150 Transmission getting hot. What are my options?

[GMcD]

My 2016 ram has the pentastar and 845re transmission. I recently bought it used and though it runs great and the transmission shifts great with no issue, it’s running hot to me. On the interstate it runs around 199 but once i get into the city with stop and go traffic, i can see 222 at times (this is flat ground, no hills). I ordered a Revmax transmission heater blocking plate but is this the best option? I suspect the transmission heater on the side is bad but i can’t verify it. Whats everyone’s thoughts? Truck has 65k miles. Thanks.

Starting this thread to consolidate some information that we've been discussing (https://www.ramforum.com/threads/revmax-8-speed-thermostat-bypass.171776/unread) on the topic of keeping the 8hp70 cooler than stock. Here you'll see the thermostat assembly broken down into its individual...

Have a read. I make this part and I should have more ready this week, next week at latest.

I bought the Revmax kit before caulk04 made his part. They accomplish the same thing with different methods. Both eliminate the heater flow so if that is the issue, one or the other should bring you temps down. I haven't been over 165 degrees since installing mine, and that was towing an enclosed trailer through the rocky mountains. If you do install the Revmax kit, make sure you install both pieces as the forum figured out one of them alone is a recipe for failure. If you are still having temperature issues after that, check your cooler lines to make sure there is nothing clogging flow.

Cancel the Revmax kit and get one of Jesse's/Caulk04's bypasses instead.It's a better option then the over priced Revmax kit.If you want some reading here's a thread on the Revmax kit.

RevMax 8 speed thermostat bypass

Hovering around 20 lately. I do still have the grill shutters. Also just for kicks I covered most of the trans cooler with a piece of rubber to test but it didn't seem to affect the temps. The trans cooler is so high that there doesn't seem to be much air directed at it through the grill anyway.
