Thinking of getting this tranny pan

....The only thing that would worry me about running the larger pan with the aux cooler would be the inability to properly heat the fluid in the winter months. I know Mopar Performance makes a sweet aluminum pan with a drain plug and bung for a temp sensor...don't know the price, though.
You don't need to worry to much about cold weather performance since our trucks use ATF+4 (or at least you should be using it). When ATF+4 was being developed, one of the main goals was to improve low temperature viscosity. They accomplished this by starting with a group III base oil that has a special dispersant viscosity modifier added to it. It then goes through a process known as catalytic dewaxing which greatly improves its low temp viscosity. This gives ATF+4 one of the best cold weather performance ratings (Brookfield viscosity grade) of any transmission fluid. In fact, ATF+4 has a lower (lower is better) Brookfield viscosity grade then any other ATF type and most any other auto trans fluid, including most Mercon and Dexron fluid types. I think the Amsoil ATF is one of the only other fluids rated better then ATF+4.
If your curious about the technical bits, here is the SAE paper #982674 that talks about the creation of and test results for MS-9602 (ATF+4).

The Mopar Performance pan requires some modifications to make it fit the 46RE. I'm not sure if it is even extra capacity either. I want to say it isn't.

Go to page 276.
What mods are needed to make it fit? They have 2 sizes: 3.90'' and 4.50'' Deep.

Maybe Mopar has come out with a new one now that is better, but this is what I know to be true over the last few years.

Yes, it was pre-drilled for the sending unit. It also has a magnetic drain plug to catch metal shavings and pieces. I love having a drain plug. Makes fluid and filter changes so much cleaner. Just drain it out first, then drop the pan. They have the natural aluminum like the one I bought, or you can get black powdercoat or chrome.
