16 PW Trans fluid amount for pan drop

[Flryder]

I’m about to change the transmission filters and ATF on my 16 PW. How many gallons of ATF should I plan on for a pan drop and filters? I also have a transmission thermostat bypass. Any downside to running it? I live in Florida, so the transmission won’t see and seriously cold weather.

Believe the manual states 6-7 quarts during a pan drop. Not sure how much may be lost with the bypass. So if you are buying gallon jugs I would get 2.

And as a comment, there is no difference between doing this on a PW versus the same year normal 2500 with the 6.4 engine and auto trans.

I think I got almost 8 quarts out last spring when I did mine (2500 66rfe). I've read some got closer to 9. Might depend on how long you sit there and let it drip for.

When I had the dorman pan with a plug it was a little under 7 if I remember correctly. Just a drain and fill not dropping the pan.

Getting ready to do mine. Seriously considering getting the pan with the drain hole. I know you "should" replace the filter each time, but being able to quickly dump the fluid and put fresh in let's you do this way more frequently and easier.

Bought my '16 used. The trans fluid was replaced by the dealer prior to me buying it....but after looking at it they used RTV or some type of sealant on the pan. Meaning it's probably going to be a PITA to remove and clean up.

I would not recommend the dorman pan. I bought it and put on my truck when I first did the filters after buying the truck 5 or so years ago. It worked great as far as doing a drain and refill yearly like I was doing. Then last spring I went to drop the pan and change the filters again. The pan had warped around a lot of the bolt holes and would not seal with a new lubelocker gasket. Luckily I kept the oem pan, so I cleaned it up and threw it on.

or maybe you over tightened the bolts. theyre probly only spose to be about 5ftlb with a gasket

You won’t lose any more fluid than you would with the oem termostat vs the bypass.

I would usually order 10 qts of Amsoil when I did mine and I would do oem filters.

If you do go with the Dorman pan with plug I highly recommend replacing plug with a better seal washer. When I went to drain mine and replace plug it wouldn’t seal very well. Lubelocker gasket is also recommended.

I let it drain for a couple hours and got well over 2 gallons out. I used Permatex Right Stuff black 90 minute gasket maker on the stock pan. I used Mopar filters as well. All set for 30k miles.

Also, torqued the 15 pan bolts to 105 inch pounds

If you plan to do it every 30k I would recommend a lube locker gasket or something similar. You will save yourself a lot time and money by having to clean the pan and bottom of trans each time. And no waiting for the gasket to set up. They are reusable gaskets so no need to replace them each time.

Thanks for the tip. I will do that next time I change the ATF. I had Lube Locker gaskets on both axles of a 98 Wrangler TJ that I had before. They never had any problems and made changing the gear oil a lot quicker and easier.

Most trans filter kits offered for these come with a pan gasket. Not saying the Lubelocker version isn't better or anything, just that gaskets seem to be pretty common on filter kits.

This is true but if going with oem I’m not sure it will. You are right that most after market kits do have a gasket. In the past I would buy an after market kit just for the gasket and then buy the oem filters

I have had some poor results with gaskets on the RFE transmission pan. I have used a Felpro cork gaskets and they seemed to squeeze out too much when I torqued the pan bolts. I have also used rubber pan gaskets and it squeezed out as well when I torqued the pan bolts and weeped ATF. Both of these experiences happened on my previous 1500 with a 65rfe which had a similar pan. I do have experience with Lube Locker gaskets on differentials and if they make the transmission pan gasket the same type of construction as the differential gaskets I would think they would not squeeze out and possibly leak.
