Has anybody installed these diff covers and transmission pans on a newer Cummins Dodge? I am thinking about installing the front and rear diff covers and deeper tranny pan on my 2007.5. I know the install should be straight forward, but I don't want leaking covers on a new truck. I plan on doing it myself if I do it at all. Also, I plan on replacing the fluids with synthetic oil. Is it a bad idea to change to synthetics on such a low mileage truck(6K miles)? Thanks for any info.

I have all the covers on my truck, straight forward no issues... just make sure you buy enough oil go by the mag hytech directions cause thr front and rear diff hold about twice as much oil as the covers

I have the front and rear diff covers, but they haven't come out with the tranny pan yet to my knowledge. Installation is easy, but I do get a little rubbing on the front diff cover from the steering.

I did the tranny and rear cover. Rear cover has a reuseable seal, same as the 5.9 truck but they did away with the reusable seal on the new tranny. You have to use black silicon. Mine worked well. I have no leaks. The new tranny fluid and rear end fluid is synthetic already in the new ones. So I just used the new factory stuff. These upgrades make it alot easier changing the fluid and give you more capacity. I got my pan from Geno's Garage pretty cheap and I think that is where I got the rear end cover too. Not sure about that because I took it off my 5.9 when I got the 6.7.

It's the same pan as the 545RFE and 45rfe.

When i installed my front and rear mag-hytec covers I purchased a case of oil. I now have 1 quart left over. The rear took 7 and the front took 4 yes QUARTS.

I tried both the front and rear and there was a serious clearance issue with the front on my 0.75 stock 2500. Mag and Geno's were great and accepted the return. Rear looks and worked great. Tried a different brand up front and still had issues. I hope you haven't got a special truck like mine. I think my truck took the short truck carrier to the dealership.

i had rear and front covers on my 07.5. neither leaked but the first time i drove it with them on the steering rod rubbed about a 1/2" of metal of the front one. and it is impossible to properly tourqe the bolts on the front one. a couple of the top bolts can only be hand tightened with a allen wrench. i was always waiting to see a hole appear where the rub was.

Glad I heard about the clearance problems on some front covers and steering arm. I am sure they are great covers, but I don't want to deal with that on a new truck. Thanks for the info.

Nah, most they would do is void that gasket/seal warranty if you bought the gsket and seal coverage... Unless you eff up and put the wrong oil in it, or something. You could always ask your preferred dealer and see what they have to say. It's only a phone call.

egl1962, sorry about your issues but I am glad I am not the only one who had the problem. In order to torque the top bolt, it really helps to jack up one side of the truck. All of the sway bars and steering links open up and it is real easy.
