Hi Guys!,

At what mileage point do I need to change my Automatic Transmission Oil and Filter for the FIRST time?

It currently has 33,000 miles on it and is performing fine. I just want to service it properly, as I'm sure a rebuild would be very expensive...

Any feedback is appreciated! :-)

 

I service all my auto trannies @ 50,000 km intervals. That would be about 30k miles.

 

Wanna say the service schedule was originally 45k but think it was changed to 60k with some service bullitin or something

 

For pickups (non-chassis cab) the first mention is on Page 148 of the manual at 60k miles (fluid and filter) if used for police, fleet for frequent trailer towing.

I would recommend changing it regardless at 60k because there's lots of crap in there from the factory/parts wear during break-in.

 

I have plans to change the Transmission fluid and filter myself. Actually I have heard it has 2 filters.

Any tips/advice you would give a person who is about to do this service? Anything to watch out for?

I have performed tranny fluid and filter changes before, but not on this transmission... Thanks

 

I suggest getting a larger after market pan with a drain on it, also different second filter for the 4X4 so make sure you get the 2WD one

 

Every 30k miles according to ram toolbox app for 2012 6.7

 

I have about 52,500 miles on mine. Just picked up enough Amsoil ATF to change the transmission, transfer case, and possibly the power steering. Read an article through TDR about changing the trans fluid. The guy that wrote it felt an aftermarket pan wasn't neccessary since the temps stayed within acceptable limits with stock. I know the benefits of extra fluid, but decided to see how it goes for about 30k miles with the new fluid to see if it is really neccessary. For ease of draining, you can always get a B&M Universal drain.

I know that the deep pan dropped 5-10 deg's off my trans temps. If you haul in city traffic during hot temperature over 90 deg's, you know that you transmission will get hot. Mine would run up to 220 deg's when I was in Kansas last summer in traffic and would cool down to 150's on the interstate. The hood of the truck was so hot I couldn't open the hood without gloves.

I change my oil after the summer, each year regardless of mileage. Its excessive trans oil temps that will kill ATF fluid, not mileage.
