Just for reference, my last truck was a Dodge 1500 4x4 with the Hemi. The 545RFE (little brother to the 68RFE apparently) liked to run hot and I mean HOT. I put a PML extra deep pan (https://yourcovers.com/transpan_11039.php) and it had the fins in it. I also installed a trans temp gauge since I now had the ability to and just driving down the road it would run up to 250. If I was pulling anything it would peg the gauge but being it was a trans temp gauge, it only went to 250 so it's peg was maybe 265. I thought there must be something wrong with my gauge or sending unit but after letting it sit overnight the pan was still over 100 degrees. I had to add 2 transmission coolers to keep it stable under 220 so these pans aren't any sort of a magic bullet by any means. Having the extra fluid was a nice "safety factor" I guess since the fluid got so hot it at least help me sleep better thinking that maybe my fluid wasn't on the verge of breaking down after driving 20 miles.

My 2008 with the 68RFE has never gotten over 130 and it's all stock. I have no reason to dump nearly $300 into a pan that *might* knock 5 degrees off the fluid that's sitting in the pan, but I have a feeling it's not even sitting in the pan long enough to do anything really. It's being pumped all over the transmission while the engine is spinning the pump.

Just my $0.02
