Legal disclaimer- South East Mopars and myself are NOT RESPONSIBLE FOR ANY SCREW UPS, BROKEN PARTS/TOOLS, PROBLEMS, INJURIES AND/OR DEATHS. YOU ARE DOING THIS AT YOUR OWN RISK. Just because I did this myself, does not always mean that you can, I still recommend PROFESSIONAL installation. ALWAYS use proper equipment, safety precautions and jacks/jackstands that are rated for the weight of the vehicle or higher.
(I had to omit the preface to the DIY due to the size, but all the install information is here)

Here’s what I used:
½” deep well socket (3/8 drive) and 6” extension
9/16” socket for the gearshift guide bracket
7/16” socket and 7/16” deep well socket (shorter socket should be 1/4” drive for the throttle and gearshift linkages)
#25 torx screwdriver (#25 torx socket will help as well for stubborn screws)
4 cans (yes 4) of brake parts cleaner
1 trans pan gasket and filter. I prefer the rubber gaskets.
10 quarts of ATF +4 (You’ll use more than normal due to pulling the valve body. Take back the extra.)
1 Sonnax “Sure Cure” kit

1 Superior TCC boost plate Part # K065
Directions for Transgo Shift kit if you’re going that route
5/64” Drill Bit - Transgo only
3/32” Drill Bit -transgo only
Drill - Transgo only
Inch/lbs torque wrench
Long needle nose pliers
standard screwdriver
small woodworker’s awl with a curved face
WD-40 to lube the linkages where they connect to the linkage shaft
FSM for your particular vehicle for a VB teardown
LOTS of baggies and a Sharpie
A small funnel that will fit into the transmission dipstick tube
4 rolls of paper towels or blue shop towels; you’ll be getting ATF everywhere
A really big catch pan. The 15 quart black Blitz pans work great

So here’s what I did:

Put the front of the truck up on ramps or elevate in some other manner
Set parking brake
Place vehicle in neutral
Disconnect negative battery terminal
Give the throttle and gearshift linkages a good spray of brake parts cleaner. This picture was pre-cleaning:

Unplug the two sensors, be careful with the clips.

Then I removed the linkages with the 7/16” socket on a smaller ¼” drive. I tried an open end wrench, but I couldn’t get it into position. I had to approach the top bolt from the top and only got about 2 clicks at a time to loosen it. Remove the spring from the throttle linkage by going for the end attached to the far anchor first. After you loosen the throttle linkage, loosen the big 9/16” bolt just right of the linkages that acts as a guidepost for the throttle linkage. You could remove the plastic top to this linkage as it’s the same as a ball hitch receiver used for towing, but I was concerned that the plastic would be brittle so I opted to remove the guidepost. After the throttle linkage has been loosened, push up on the anchor point to push the anchor clear. You may need to pry up gently with a standard screwdriver to get it to slip loose. Don’t lose the spring.
The gearshift linkage is much easier to get to. Loosen and lift it off as well. Pry gently if you need to.

Now for the fun part, CATCH PAN ready! If you’ve installed drain plug, you da man! If not, you will after this next step:
Loosen all of the pan bolts toward the back of the vehicle and remove. Then work your way up the passenger side and driver’s side. Then remove all but the two corner bolts on the driver’s side front corner. Loosen them about 3 turns and using a standard screwdriver on the OPPOSITE corner of the pan (passenger rear) pry gently where you see the gasket sticking out. Get the catch pan ready because she’s gonna dump tranny fluid like Niagara Falls. After it slows down, continue to remove the screws, but brace the pan with your other hand. Lower the pan and aim for the catch pan as you tilt it in toward the center of the pan. You should probably be wearing about 1 quart of ATF if you did it right, more if you’re slow.

You’ll notice a flat filter covering the VB, remove the 2 screws holding it on with a #25 torx screwdriver. They're very long, but don’t lose them in the catch pan. The filter will dump more ATF from the oval hole when it comes loose, so be ready. Discard old filter.

Now what we came for: the Valve Body. I believe there were 9 bolts holding up the Valve body in my 2001 Ram, all were 7/16” and they looked like this:

There are three different lengths of these, so mind where they came from. The longest 3 go on the passenger side. The mid-sided bolts go in the holes closest to the ground, and the shortest bolts go in the holes closest to the transmission. My valve body didn’t let go until the very last bolt was loosened considerably. Get ready for another flood of ATF to come raining down.

As you lower the valve body down, the accumulator piston and 2 large springs will undoubtedly fall out from the passenger side. Make sure you clean them good at set them aside. The fat spring sets on the VB then the accumulator piston sits inside it and the skinny long spring sits inside the accumulator piston on top. It’s really obvious where it goes back into the transmission housing.

On the driver’s side there is a Parking Sprag connected to the “rooster comb” that is attached with a small “e-clip.” Transguy37 snapped a good pic of what I’m talking about:

Pop that clip with a standard screwdriver and push the parking sprag mount up and out of the way. The VB should now come out of the transmission case. I set the VB on a garbage bag and took it out from under the truck. I also put the pan back on with 2 bolts to catch the dripping ATF.

Spin the VB around and around a few times to get out all the extra ATF you can and spray the outside down liberally with brake parts cleaner.

Set it down somewhere clean to work. Also, somewhere you don’t mind getting ATF all over. Get your baggies ready.

If you’re going to do the shift kit stuff, follow the FSM tear down procedure. If you’re just installing the Sonnax parts, you do not need to tear down the VB, just remove the outer parts by following the “Sure Cure” directions. These are really great directions, and very simple to follow. Be VERY careful when you remove the rooster comb not to loose the detent ball or spring. If you easily forget things, I would photograph everything before you disassemble in as many angles as possible to assist with reassembly. Use a different bag for each set of items in the tear down and GO SLOWLY! You can’t afford to loose a spring, clip, or check ball. Make note of each screw that is a different length and where it goes. Sometimes it’s obvious, sometimes not so much.

Here's some pics I took to help identify some parts:

When you’ve finished the VB work, it’s time to reinstall. Make sure you don’t forget the accumulator and springs. Get a set of long needle nosed pliers and a couple VB bolts ready. Swing the VB up into the transmission and push the accumulator into its port.

Now comes the biggest PITA part of the job, at least for me: Getting the parking sprag back into it’s holder and installing the E-clip.

You may need to work the rooster comb arm around so the parking sprag holder is visible. Push the sprag through the holder and set the E-clip in the groove by hand. Then carefully and quickly grab the needle nosed pliers and gently squeeze both the open side and the back side of the E-clip to seat it. If you loose the E-clip, the Sonnax kit includes another, but make sure you know the lost one is clear of the VB, you don’t want a loose piece of metal floating around in there. This literally to me 1 hour to do. I dropped the accumulator piston and springs about 8 times and my arms got really fatigued holding the valve body up. After you get the E-clip in, take a standard screwdriver and position the clip so that the action of the parking sprag moving back and forth won’t pop the clip. It may not be necessary, but why risk it? Carefully guide the VB up into the housing paying close attention to the park/neutral switch sensor position. The notch in the end of rooster comb should fit right into the ball of the sensor. Guide the linkage arm up through the port on top of the VB case and set a couple bolts on each side of the VB to hold it in place. Reinstall and tighten all 7/16” bolts. Then set a new filter with the long #25 torx screws.
