Found this for our ZF8

[Spinrite]

Upgrade for our transmission pans on all JL & JTs with bonus drain plug.

Not buying a high-dollar pan that I, the end user, have to “grind to fit”.

Solving a problem, that isn't a problem. If you buy this for a cooler tranny, then you need to add a better tranny cooler. That will work better than a bigger pan.

The ZF 8 speed is designed to run warmer just in case some are worried about high readings compared to previous vehicles, FYI.

Thanks for sharing OP. Not high on my list though. I would consider an inline cooling option first.

My 8hp75 transmission has a factory cooler with a thermostat. I monitor my transmission fluid temperature and It has never had an overheat issue. It runs around 200 degrees F. Not sure this is pan is needed.

My old ZF 8HP70 stayed in the 195-199F range while my current ZF 8HP75 runs 168-172F

Chrysler’s 850RE seems to run a tad warmer than the ZF units

I bought one, not really for cooling, but for the built-in drain plug. The cooling and additional fluid is just a bonus. I plan to do several drain and fills after swapping the PPE for the OEM to be sure that I get most of the old fluid out of the system. I would rather not drop the pan every time to do that.

At $30/quart, I’m not sure you’re getting your money’s worth here.

Adding a drain plug is easy. There are a lot of inexpensive kits, probably around $10 or less. You just drill the hole, where you want it, and lock in the plug, with a couple of wrenches or pliers. These have been around for many years.
Here is a simple example:

To make it even simpler, you could use a plug like that, and add a Fumoto Valve.

IMHO, wasted money, for this pan. People would be better off just adding a drain plug , to their existing tranny pan, and adding an inline cooler($40-$60), if they are worried about excessive heat.

Meh...to each his or her own. I actually bought a weld-in plug, but elected to go this route. I am good with my choice.

It is $15 a quart online and dropping the pan/changing the filter leaves as much in the transmission as you remove by dropping the pan. ZF does not recommend flushes so this is the next best thing.

Most will not change the fluid at all since FCA states that it is a "lifetime fill" but we all know that is bovine scatology. I just prefer to keep my JL well maintained.

I'll be changing mine at 50k miles and every 50k thereafter. At my current miles per year that's about every 4.5 to 5 years. I can get that ATF for about that $15 price from my dealer and the entire pan/gasket/filter combo is about $90 from them too, parts mgr gives me a deal
Having a drain plug would be nice but I don't mind doing the pan exchange since it's only every 5 yrs give or take.

You are correct, to each his own.
But, for me, $10 + $30 + $60= $100 for the modification of your factory pan, with a Fumoto Valve, and an inline tranny cooler, that will cool better, is an even better option.
The price of this PPE pan is around $300, and it won't cool near as well as an inline cooler.
Then again, the PPE is pretty.

Another thought. The factory pan is made of steel, which bends, when bumped by a rock, or branch, off-road.
The PPE is made of cast aluminum. We all know what happens to cast aluminum, when hit or bumped. It cracks, or breaks.
Then again, those are just my thoughts, and opinions.
When it comes time for a tranny fluid change, I think I know which route I will be taking.
