The MegaCab currently has 52,644 miles on it. I'd been contemplating performing the transmission service on it since I crested the 50K mark, but the weather just now was cooperative enough to do so.

I purchased the filters (Spin-on # 5179267AC $14.56 and Sump # 5013470AD $26.33) 2 gallons of MOPAR ATF+4 (# 5013458AA $24.12 each) and 4 quart bottles (# 5013457AA $6.05 each) and one tube RTV Sealer (# 5010884AA $4.62) at Mann Chrysler in Richmond, Kentucky.

Apparently the Cummins Gorilla is no longer installing oil filters on the 6.7L's in Indiana. They are now installing the spin-on filters and tightening the single screw that secures the sump filter inside the 68RFE's nowadays. :roflol: He must have had a long run as CTD Oil Filter Installer as my 1998 RAM 2500 12V, 2000 RAM 2500 Quad Cab, and 2003 RAM 2500 Crew Cab all required a combination of cussin' spittin' and other colorful ideas in removal of the OEM oil filters.

First snafu : Dealer said I'd only need about 5 or 6 quarts of ATF+4. I called BS on this as my 2000 Dodge RAM 2500 Quad Cab w/CTD & 47RH required nearly 8 quarts when I changed it. You'll notice I purchased twelve quarts total......I had to buy a portion of it in quart bottles as I took the last two gallons they had on the shelf. I asked about their return policy as I was 26 miles or so from Richmond and that I'd rather return some later instead of being too low after the change. No problem....

I live about 26 miles from Richmond, so the truck had a good 60 miles +/- by the time I got home.....suitable for a good drain and scalding when I drop the pan. :roflol: I'm a glutton for punishment I guess....

I get the pan off and prepare to remove the old RTV from the pan while the fluid continues to drain. The spin-on filter (this filters the transmission fluid from the transmission cooler via the return line) is to be tightened ony 3/4 turn after gasket contacts upon installation. The Cummins Gorilla sure did a lot more than that on mine. Time for the small oil filter wrench.

The single screw that secures the sump filter was not torqued to any specs. I don't have any torx sockets, but do have a torx screwdriver assortment. I eventually had to wrap a rag around my T-25 and put a pair of channel locks on it to remove this poor screw. Cummins Gorilla strikes again!!!!!!

The above steps probably only consume about 30 minutes or so. The sump filter also came with a new o-ring seal where the neck goes into the transmission. They send a replacement for a reason......so I then spend the next 3 hours or so trying to remove the old one. :poke Knowing what I know now.....the old one would still be in there. :damnit Anyway, after more cussin' and spittin' the new o-ring is in.

I tossed in 6 quarts off the bat, checked for leaks, and re-checked the fluid level. I then added two more quarts. I then have my wonderful wife Becky perform a 10 mile round-trip test drive (a severly soaked right arm sleeve of a sweatshirt and center console don't play well together) and re-check....adding two more quarts. The level is now between the two upper "HOT" marks, but I'll most like add another 12 to 16 ozs after I test drive it on a longer trip sometime. Essentially I'll be at 10.5 quarts or so.....a far cry from 5 or 6 quarts, huh???

The OEM fluid.....even with some light towing that I have performed....still really looked very good. I'll most likely just perform a flush around 100k miles and skip the filters then.

I cleaned up my work area and then cleaned up myself......including ditching my blood-soaked appearing sweatshirt, and then took Ol' Blue out for a drive. All is well......... :happydance

Automatic Transmission Maintenance

Sounds good. 'Bout time they got around to installing proper filtration. I've been running 727's for over 30 years and always installed an additional filter in the cooler circuit. Never had a tranny failure or problem in over 300k miles on 2 different 727s. The first one I had in a '70 Chrysler New Yorker had 189k on it and was running great when pulled 6 years ago, still sitting on my garage floor today as a spare, never rebuilt or anything except fluid and filter changes. My '07 Ram now also has the 48RE with an after-market external filter cobbed up on it:

The first pic shows the original setup/line routing and connections with larger lines and a smaller filter. The current filter holds 2 1/2 addiitonal quarts and is a true bypass filter element plumbed with 1/4" lines. I plan to run 50k mile oil change and 100k filter intervals as well. It's cheaper and easier in the long run than paying for transmission repairs and/or tons of fluid for more frequent oil changes.

What is the factory spec'd service interval on the 68RFE these days?

Nice mod, Nadir......you should compose a thread about it if you have not done so already.

I'm too lazy to go to the truck right now........but I *think* the service interval is 100k Schedule A and 50k Schedule B.

The way I look at it : Filters and fluid are inexpensive / Transmission repairs are expensive!!!!!

That sounds about right, and if it is it's that external filter allowing it. I believe the previous 48RE like in my '07 is half that distance, but I also am too lazy to go out and look right now. :wave

Can do......fire up the grille and get me some Coors Longnecks (for AFTER the job is completed).

Of course......your sump filter gasket is NOT going to be replaced. :happydance

During the oil change is a good time to put the Mag Hytec pan on, thats when I did mine. Like GS, one time being covered in red trans fluids is enough. Although my sump filter gasket came out easy. Maybe the Cummins Gorilla that did GS's truck missed my truck:roflol:

Mine filters were replaced when i had my gauges put in, at 10500. So i will prolly do it again this summer at 55k since it tows alot and add the pan at that time.

It wasn't really *that* bad.....just some soaking of the right sleeve primarily. I may even have a technique in mind that may make it a little cleaner however!!!!!!! :roflol:
