I have been looking for an online source for a diagram of a transmission for an 04 1500, with no luck. Is there a Dodge or aftermarket site that shows a photo or drawing of the transmission as well as a service manual?

My ultimate goal is to learn if and where the test port on the 5-45RFE automatic transmission is located so I can install my trans temp guage. If anyone has more information on this specifically or can point me to some diagrams it would be greatly appreciated.

Thanks.
