PPE Transmission pan

[Poko]

Ia have a 2023 jl rubicon with the auto trans (3.6l). Thinking about replacing the stock pan with the PPE aluminum pan that has a replaceable filter AND a drain plug. Anyone using these?

How many miles do you have and how long are you planning on keeping your Jeep? Considering a transmission service should be done at about every 50k-60k it seems like kind of a useless feature of a part to make a fluid change easier/faster if you only use it once or twice in the life of the vehicle. Changing the pan itself will take care of one of those services.

My 2020 has a replaceable filter in the stock pan. I'd like to have a drain pan, but to the point above, it really isn't necessary unless you do regular changes.

I have that transmission pan. It’s definitely more substantial than the flimsy stock piece and the fins should help it cool the fluid more efficiently (my main reason for buying it).
That said, you can service the trans using the stock piece by dropping the pan to change fluid.

Let us know how it goes... My first AT service is coming up, and I'm considering this myself. Some guys like to just drop the pan, but I'd like to have a plug to reduce the mess and be more accurate in collecting & measuring how much actually pours out. That, and I'd be inclined to do more frequent drain & fills between filter changes.

This fellow did a "no pan drop" fluid change using a fluid pump to suck most of the fluid out of the pan. Even if you are going to drop the pan, sucking the fluid out of the pan first will reduce mess considerably. Probably no mess at all if it is left to sit for a while before dropping the pan.

I use the suck and spit method on all my other vehicles as there isn't much of a risk of metal shavings in the pan. The Jeep gets beat on a little harder and will likely have a little more debris in there. Dropping the pan and cleaning it well goes a long way.

I used a large Rubbermaid pan to catch the oil and was able to measure it that way, however, I agree that the drain plug would make it easier.

I have three vehicles with the 8HP trans. I put the PPE pan on one of them so far. It does help keep the transmission fluid cooler, but it also take significantly longer for it to warm up. Thankfully that vehicle stays inside over the winter or I don’t think the transmission would ever get to operating temp if it was cold out. In the summer and towing it’s brilliant. I probably won’t get one for my 2 door even though it’s the “trail rig” because it has a full Artec underbelly skid system. I’ll watch the temps closely this summer and see if it could use some more help with the limited airflow. For a “run around town” vehicle, the stock pan is better imho.

I always use the Dorman pan. Has a drain plug and replaceable filter.

More fluid isn't going to help anything. The fluid will heat up more slowly, and cool down more slowly, and the pan will hang down lower.

Here's a twist - the automatic transmission fluid service on the ZF8 transmission in my BMW consists of replacing the pan each time as the filter is integrated. The pan is plastic but there haven't been any issues with excessive heat or them taking a hit that cracked the pan. The pan actually has a drain plug which will makes the job less messy. Only some drips/drops remaining once the pan is dropped. Interestingly enough, it takes a different fluid than what the Jeeps use. It's ZF8 labeled and while my initial suspicion was that the Mopar 8/9 fluid would be one and the same, just different packaging, it's not. In case you ever find yourself on Final Jeopardy and that question comes up, I hope you bet big.

Some interesting misinformation here. I didn't use the PPE version, but rather another brand with an even deeper profile. Goals: Drain plug. Increased fluid capacity. Both achieved.
When simply dropping the OE pan you will get about 6 qts out. The torque converter, pump, and misc galleys retain about 3 quarts that you won't get out by simply dropping the pan. There is a process for evacuating the unit completely. it's a PITA.

Greater capacity is all benefit and no negative.

I change trans fluid every 25,000 in all my personal and business vehicles. Used Oil analysis proves this out.

So you're saying there is 9 quarts of tranny fluid in there? Kinda killing the case for increased capacity if that is the case.

Also the dealer's price on fluid was $40+ per qt so dayum.

yep - 9 QTS total capacity. With the pan I now have, that figure is about 10.5 QTS. Greater capacity is a good thing as it reduces particle concentration, runs cooler, and is generally more stable as the additive package yields to sheer.

Mopar 8 & 9 is $16 / qt at online auction house.
