Thermal bypass

[smrdmr]

Looking for some info on installing a trans thermal bypass valve on my 2019 Ram 1500 with a 5.7. Also what is the best trans pan with filter to buy? I don't want to have to do this job 2 times especially at the price of the fluid. I'm either using the Mopar fluid or ZF fluid. I was a tech for GM for 30 years so I'm not stupid and please don't respond with stupid answers.

Here's a current thread on replacing the pan on the 8HP transmissions (70 or 75). It covers the pan and thermal bypass

B&M pan

Went smooth at 43800 it took 10 amsoil squeezers to fill instead of the first time at 10000 mi.with OE pans 6 but doesn’t reduce temp so I will put a cooler between the intercooler and radiator before next trip.

There have been lots of people who have used Valvoline Maxlife fluid in these transmissions without any issues and have collectively racked up in the millions of miles.

I would look at the PPE aluminum pan. It has a replaceable filter plus it holds a little more fluid. And this bypass valve is very popular. https://yourautohuckleberry.com/store/transmission-parts/8hp70-8hp75/thermal-bypass-valve/

The bundle option provides an aluminum cap to replace the POS plastic OE cap.
