we have had guys from time to time buy a ten lot, you can make a little money selling these 20 bucks a pop delivered. The issue is sometimes they arent avail, so this is more of a service plus you can make a little.

If the Mopar gaskets for the 68 rfe are like the one I had on my 06 48 rfe it's reusable, I know as I reused it when the filter was replaced an with out leaks, you just have to be careful when removing the trans pan...

I ordered the lube locker gasket off of summit racing seems to be a good gasket from the reviews. Any experiences?
I have one on my rear diff and transmission they are great for reuse. I have upgraded to the 68 rfe canister filter with my PML transmission pan , it is about 2 1/2 inchs taller then factory filter.

I want to change my transmission fluid and filters. I have been doing some searching but i can seem to find the oem filters does anyone know where to get the fluids and the filters online or is there a better filter setup you recommend?
check out the PPE pan. You have 2 choices and they separate the filter from the pan. My trans guy says it's one of the nicest setups he's seen.

If your trans cooler lines come down and sorta bend under the trans pan, the PPE filter won’t work and PPE doesn’t offer the pan with the corner clipped for the cooler lines anymore. I inquired to them last January & ended going Revmax.

Either go to dealership for the parts or try
Advance autoparts they also have the transmission fluid and also while you’re under there replace the nylon nipple for a steel nipple they have a habit of breaking off, you can find them at ATS DIESEL or
REV-MAX

The letters are just miss printed they are the same filters on both sites
The suffix letters indicate a revision or a vendor difference. A "D" indicates something different from a "C." The difference could be who made it or something you can't see externally.

I usually buy my filters from Rock Auto they have both OEM and aftermarket filters I use Baldwin and it comes in a kit both filters and a gasket. Hope that helps. You go by the year of your truck and the motor you have and happy hunting.

I bought a doorman pan with a drain plug to make future changes less messy. It came with a nice quality rubber gasket as I recall.

I’m running valvoline ATF but Redline is recommended by quite a few on this forum for better shift quality.

Go here, I changed mine in May 22


I recently changed my 2500 Diesel's transmission fluid and filter. Some auto parts stores don't keep very many transmission filter kits in stock, possibly since so many people choose to not change the fluid. I tow a mid-sized 5th wheel with mine, so I changed it around 50K. There was also a "return-line" filter inside my transmission that I had to purchase that filter separately (not in the filler/gasket kit). If you have never done this, don't rush, take your time and keep checking yourself; it is not that difficult. I make sure to have the wife's car on standby and set aside all day to "get it right". I also align the new gasket along the pan and count bolt holes before I begin to make sure I have the correct gasket. Loosen the bolts so that the pan lowers toward the back to drain. It will drain for a long time too. I also clean the pan real good with Brake-kleen and paint it with red "higher-temp" red paint before I put it back together. Don't forget to clean and replace the magnet. You can even write the mileage on the pan with a sharpie. Always pour the dirty ATF back into 1-gallon milk jugs so you know how much ATF came out. You can also see how "clean" it really is through the clear milk jugs. I also used the "best" brand-name ATF Advance Auto Parts had in stock. Plan to change it again at 90-100K too because you are really only changing about half of the fluid. I prefer to use Permatex non-hardening gasket sealer also, and don't skimp on sealant thickness on all four surfaces. Also tighten the pan bolts gradually, and not too tight to bend the pan. And, after driving, keep checking the level and top it off gradually over several days.

I always keep an empty 5 quart oil jug so I can measure how much trans oil drained out. Milk jugs ok, but can't read partial fill for the last drain amount.

Awesome thanks for the tips. I purchased the molar atf +4 I see y’all recommend others what do you think of the molar stuff I’ve heard it should do just fine. Also how often do the nylon threads tend to fail? is that something that could wait for the next trans service maybe?

Mopar ATF+4 is likely just a standard Group III quasi-syntheric with requisite +4 friction modifier additives. That has moderate oxidation life.
Red Line +C ATF and Amsoil MVATF are true Group IV & V synthetic oils the provide maximum oxidation life.

This is critical if you haven't removed the trans oil cooler thermostat.

Without being able to lay my hands on the ATF+4 specification sheet, I can probably estimate that ATF+4 uses a Group III base stock, if nothing more because of the original release date of the product.

However, I do not believe that the base stock is the critical element. The additive package which has been developed around the clutch materials and engagement strategy is still a proprietary compound (recipe) even though there are now a couple of companies currently licensed to produce the fluid.

They're both critical in transmissions.
Base oil stability under heat is critical to preventing varnishing of servo valves and clutch facea.
