Your owners manual will have the fluid types and some guidance on how to change. If you don't have a copy a PDF version can be downloaded from the link on the left side of
https://www.jeep.com/hostb/crossbrand/owners/en/ . Note the manual transmission fluid is, in theory, lifetime unless water contaminated. As to capacities and how to change info that's not in the owners manual you would have to check a 2007 factory service manual. Copies are available at
http://colorado4wheel.com/manuals/Jeep/KJ/ but not for 2007 although as long as your manual transmission and such are the same as ones used in earlier years it's likely that an earlier FSM will have the needed info BUT I'll caution you that the FSMs are not consistent on some capacities, the cooling system capacity is a good example.
Wish I could be more help but there are no KJ CRDs on this side of the pond after the 2006 model year.
