Valve body is easy. The only bad thing is many manual valve bodys require some internal mods. That may be the tricky part.
whats up with this is this good

TCI® 221100
Turbo 400 Full Manual Valve Body
Shift Pattern: Park— Reverse— Neutral— First—Second—Third
This Kit Contains:
(1) Turbo 400 Full Manual Valve Body
(1) Separator Plate & Gaskets
(1) Pressure Regulator Spring
(1) Second Gear Release Spring
(2) 1/4" Check Balls
(1) Vacuum Modulator Plug & 0-Ring NOTE: You must reuse stock manual control valve.
IMPORTANT: Before you begin installation allow transmission to cool to avoid bums from hot fluid or parts. Select a well lighted work area and it Is very Important to keep all parts clean. Use a box or pan to keep transmission parts from getting misplaced. Wash parts thoroughly with a good solvent.
STEP 1. Drain and remove transmission from vehicle. (Remember to dispose of fluid in a proper, safe way to protect our environment.)
STEP 2. Remove transmission oil pan.
STEP 3. Remove transmission filter (There are two types)
1965-68 models will pull off, other models bolt on and off.
STEP 4. Remove valve body, separator plate, check balls and center support bolt.
STEP 5. Remove pump, forward drum, high gear drum and band. Discard band. Band will not be used. Remove and discard piston and spring assembly. (See Photo A).
STEP 6. Remove second gear clutch pack. Remove snap ring in case. Remove clutch pack. Remove center support snap ring and center support. Remove rear servo piston. Inspect center support bushing. Replace if necessary. Center Support Modification (See Photo B). Remove and discard second seal ring from top. After modifications are complete. Re-install center support assembly and second gear clutch pack. Refer to transmission manual if you are unsure of the proper installation.
STEP 7. High Drum Modifications: Remove piston assembly from high clutch drum. Do not use center cushion seal on the high clutch drum. Discard this seal. Re-install piston into high clutch drum. Set clutch pack clearance: .070" to .090".
STEP 8. Re-install high gear drum and low gear drum.
STEP 9. Remove pressure regulator from front pump (See Photo C). Push down on the aluminum sleeve and remove snap ring. Slowly remove booster sleeve assembly. Note: UNIT HAS SPRING TENSION. DO NOT LET SPRING ASSEMBLY FLY OUT OF BORE. If sleeve is stuck, tap on it lightly to free from bore. Remove the booster sleeve and valve pressure regulator spring, spring retainer, shims (some models have one) and the pressure regulator valve.
Disassembly and assembly (See Photo D). Replace OEM pressure regulator spring with TCI® spring supplied in kit. To install the assembly, slip the retainer in place with the tangs toward the spring. Slip the spring over the small end so it comes in contact with the retainer. Push up on the booster sleeve and Install new snap ring. Make sure it seats completely into its groove. After modifications are complete, re-install pump assembly.
STEP 10. Remove Rear (Reverse) Servo cover (six bolts). ring in case. Remove clutch pack. Remove center support Remove rear servo piston (See Photo E). Remove and discard the two rings from the reverse accumulator.
STEP 11. Using a flat punch tap 1/4" check ball supplied with this kit into accumulator drain (See Photo F).
STEP 12. Next, check surface of rear servo cover. Surface should be flat and smooth. Take some sand paper and attach to a flat surface. With even pressure sand the servo cover. Cover surface should sand evenly all around mating surface. (If warped, replace). Wash cover and re-install rear servo assembly. After installing rear servo and cover, you should air check servo for proper application.
STEP 13. Install second gear release spring and check ball provided in kit. Second gear bore is located next to the center support bolt hole. (See Photo G). Install spring, then install check ball. The check ball will sit on top of the second gear release spring. Next, measure the distance from the top of the check ball to the surface of the bore. The check ball must be 1/8" or .125" below the surface. If the distance is not correct, then remove the small spring and cut one coil off the spring and re-install. Again, measure the distance of the check ball. It must be 1/8" below the surface. When the correct distance is obtained, the modification is complete and you are ready to go to the valve body assembly. This step must be done properly because this check ball MUST have proper clearance for the valve body to shift the transmission properly. Take time to do this step correctly!
STEP 14. You are now ready to install your TCI® Manual Valve Body. Make sure that the transmission case is clean and all gasket material has been removed. To align the new Manual Valve Body, Install two guide pins into the transmission case. You must line up the manual valve with the pin or manual detent lever of your transmission. The OEM manual valve is used with this valve body kit. The manual valve has an opening that the detent will fit Into. The detent lever moves the manual valve when you manually shift the vehicle. Now you are ready to install your valve body. Install: Gasket, TCI Separator Plate, Gasket, and TCI® Manual Valve Body. Bolt the valve body to the transmission. After you have started all the valve body bolts, tighten a few bolts and then remove the two guide pins and replace with the remaining bolts. Tighten the 5/16" bolts to 15 foot-pounds
STEP 15. Re-Install filter, o-rings, pan gasket and transmission pan.
STEP 16. Remove and discard the vacuum modulator. Remove the rubber 0-ring from the original modulator and install it on the new TCI® replacement vacuum modulator plug. Do not remove the modulator valve. After you have installed the 0-ring on the vacuum modulator plug, put it back into the transmission case. The fluid should not leak between the case and the new plug.
STEP 17. Install transmission into vehicle.
STEP 18. Adjust manual linkage:
A. Loosen adjusting nut on linkage rod or cable.
B. Place transmission selector lever (car shifter) in Park.
C. Align linkage rod or cable to correct adjustment and tighten nut.
NOTE: Move shifter to all gear locations and check detent locations on transmission. Some adjustments may be necessary.

STEP 19. Fill transmission with four (4) quarts of fluid. We recommend our RTF (TCI® 950600) formulated for performance applications. Start engine, place the transmission in neutral let engine run for a few minutes and re-check fluid level using transmission dipstick. Do not over fill transmission.
STEP 20. With the vehicle jacked-up and secured properly, run transmission through each gear change and check transmission fluid level again. While you are shifting gears, you will have to apply a light brake pressure in order to feel the second gear shift. Run the transmission in third gear at 2,000 RPM’s for at least 30 seconds. If the transmission binds, shift back to second gear. You may have to repeat this several times before the transmission fluid fills all sections of the new valve body and check ball locations. Usually, you will only have to shift from second to third a few times before everything operates correctly. If the binding does not disappear in a reasonable amount of time, remove the valve body and repeat pressure regulator step, second gear release spring, and valve body alignment steps. (Check to make sure the check ball is 1/8" below the surface and also check the separator plate to make sure it is in alignment with the valve body).

Chance,
Chris probably dual feeds the reverse valve body kit via VB mods.
The internal parts you remove on the TCI kit are for dual feeding the directs.
This can be accomplished externally, I know TransGo does it with a "sandwiched" plate design.
I believe Coan also does it on their reverse valve body design for the 400.
I did a Coan forward valve body for a TH350 recently and had to do internal mods.
Chris can elaborate but I believe the reverse VB design allows it to be done in the VB, it also allows a very short passage to feed the directs.

Quicker apply to 3rd gear, less clutch slippage on 3rd shift.
I've had issues using the TransGo sandwich plate at higher HP levels (over 550 HP) which I believe to be caused by too long passage with not enough area to move the required amount of fluid to TOTALLY apply 3rd gear.
