I just bought the service manual and thought it would tell me somewhere to identify the differential i have, but apparently it does not? On other forums i have been able to find alot of how-to's and exact fluid types/capacity's.

However for this dodge, and forums i cannot find anything, (why i bought the service manual) but im still not finding information in black and white.

I have never changed differential fluid and wanted to know how, how much it takes etc? I have a 2003 Laramie 2wd 1500 5.7L

Also while im on the topic, i need to know the transmission fluid capacity as well with both filters replaced? Any DIY guides on either of these?? thanks

 

Also for my transmission i dont know which one i have service manual tells me to information on body plate.. in transmission place mine says DGQ.. which does not match anything of the service manual??? I assume i have 5 speed which in manual says is DG8, obviously a typo somewhere

 

You can take the VIN to the dealer and get a build sheet to tell you everything that came with the truck. You can also email dodge and do the same.

Here are some service manuals that I know will tell you fluid capacity's

Sounds like you got the Hayne's or Chilton's "service manual". It'll want a bit less than three quarts of 75w-140 synthetic diff fluid, plus some friction modifier if it has LSD.

Yep, if it's a Hemi, it's a five speed (5-45-FRE, or RFE, I can never remember). 1500s got 9 1/4" rear ends.

When I did the drop 'n' drain on my Ram, it took just about seven quarts of fluid. I used Valvoline ATF +4. There are a couple of good how-tos on the forum. Some of them are even entertaining in a twisted sort of fashion.

 

Ya i think the manual i have says 5.5qts for tranny and about 2.5 for diff.. I have the 3:92 rear diff. how do i know if this is LSD and if i should add the additive?
