This is a tutorial on installing a Transgo 45/545RFE-HD2 Reprogram kit. This applies to any vehicle that uses a 45/545RFE transmission. All Hemi or 4.7 powered Rams, Dakotas, Durangos, etc...
First, take a look at the supplied instructions. Familiarize yourself with them well, I will elaborate on these. MEGAUPLOAD - The leading online storage and file delivery service
Also take note, you DO NOT have to install the "Heavy Duty Underdrive Snap Ring" into the input clutch/drum or springs and valves into the transmission pump if you do not want to remove the transmission from your vehicle. However, I do recommend that you do, because this gives you beefed up parts designed to handle the increased line pressure this kit gives you.
The next document you should keep on hand is the 545RFE Transmission Manualhttp://www.megaupload.com/?d=DK0NSJYO This is a very handy manual to have around. It will tell you just about anything you need to know about this transmission.
Step One: Remove Transmission from your vehicle. (Or if you are skipping the pump and input clutch portion of the install, Skip to Step Fourteen) Refer to this tutorial here for detailed instructions on tranny removal http://dodgeforum.com/forum/3rd-gen-...-tutorial.html
Step Two: Remove the torque converter. it just slides right off the input shaft. what you will be looking at behind the tq converter is the transmission front plate.
Step Three: Remove the front plate. It is held in place by two snap rings, one around the shaft, and one around the outer edge of the plate. I found that using a small flat head and a metal hook made it easy to work with. Once the snap rings are removed, I used a LONG flat head, and inserted it into a hole in the housing behind the plate, and gently tapped it out.
Step Four: Now we are left with the fluid pump, we need to remove this. It is held in place by six hex bolts. once those are taken off, it will slide off the shaft.
Step Five: Remove the input clutch assembly. it should slide right out. You are going to want to move this to a clean work bench. without a bunch of clutter. you will need to be organized to keep track of these parts.
Step Six: Remove the first snap ring on the clutch retainer. It is the one right underneath the little lip on the protruding fins. Once the snap right is out of the way, remove the metal plate it was holding in place and the few discs that are under that. set those and the snap ring in a clean organized spot. (note, the snap ring we are replacing is located at the bottom lip of the before mentioned "fins" its a little ways down there)
Step Seven: Remove the next snap ring, it is located on the outside of the fins, and is holding down another thick metal disk. once removed set those in your designated area, and keep track of the order these parts are coming out.
Step Eight: Remove the input shaft and the gear it is attached to. once again, set in clean area, in order.
Step Nine: Now we are down to ring we are replacing. It is the ring located directly underneath the bottom lip of the "fins". you should have something that looks just like the first picture below, if you don't, you probably didn't remove enough parts and need to follow directions better. Remove this snap ring, and put in the new supplied one. It is a tight fit getting it in there. I used a flat head and mallet to tap it into place.
Step Ten: Reassemble the input clutch assembly in the reverse order you took it apart, then put it back into the transmission.
