Here are the steps I used in constructing the C6 Transmission. If you have any questions, please feel free to email me. Although I am no expert, I do have access to more experienced builders!

Rebuilding the C6 Transmission

 1. Place the transmission case in a holding fixture.
2. Tap the low-reverse piston into place in the case with a clean rubber hammer.
3. Install the low-reverse clutch spring retainer assembly and retainer assembly in the clutch piston.
4. Hold the one-way clutch inner race in position and install the attaching bolts. Tighten bolts to 18-25 ft. lbs.
5. Place the transmission case on the bench with the front end facing downward.
6. Position the parking gear thrust washer and the gear ont he case. Do not restake the thrust washer.
7. Position the collector and tubes in place on the rear of the case. Install the attaching bolts and tighten to 12-16 ft. lbs.
8. Install the output shaft, and governor as an assembly. (You can leave the governer off i f you are running a manual valve body, it just servers as extra rotating weight!)
9. Place a new gasket on the rear of the transmission case. Position the extension housing on the case and install the attaching bolts. Tighten the attaching bolts to 25-35 ft. lbs.
10. Place the transmission case in the holding fixture.
11. Coat new gasket with pretoleum jelly and position on the servo cover.
12. Position the srevo spring on the piston rod.
13.Insert the servo piston rod in the case. Install the servo cover with the attaching bolts, making sure that the identification tag is in place. Tighten the attaching bolts to 14-20 ft. lbs.
14. Align the low-revers clutch hub and one-way clutch with the inner race at the rear of the case. Rotate the low-reverse clutch hub clockwise while applying pressure to seat it on the inner race.
15.Install the low-reverse clutch plates, starting with the wave plate next to the piston and following with steel and friction plates alternately. Retain them with pretroleum jelly. If new composition plates are being used, soak them in clean transmission fluid for 15 minutes before installation (I would recommend overnight!). Install the pressure plate and the snap ring. Test the operation of the low-reverse clutch by applying air pressure at the clutch pressure apply hole in case (its the 2nd one over with the hump on the top of it).
16. Install the reverse planet ring gear thrust washer and the ring gear and hub assembly. Insert the snap ring in the groove on the output shaft.
17. Assemble the front and rear thrust washers onto the reverse planet assembly, retain with petroleum jelly. Insert the assembly into the ring gear and install the snap ring.
18. Set the revers-high clutch assembly on the bench, with the front end facing down. Install the thrust washer on the rear end of the revers-high clutch assembly. Retain the thrust washer with petroleum jelly and insert the splined end of forward clutch into the open end of the reverse-high clutch with the splines engaging the direct clutch friction plates.
19. Install the thrust washers and retain them with petroleum jelly, on the front end of the forward planet ring gear and hub. Insert the ring gear into the forward clutch.
20. Install the thrust washer on the front end of the forward planet assembly. Retain the washer with petroleum jelly and insert the assembly into the ring gear. Install the input shell and sun gear assembly.
21. Install the revers-high clutch assembly, forward clutch assembly, forward planet assembly and drive input shell, and sun gear as an assembly into the transmission case.
22. Insert the intermediate band into the case around the reverse-high clutch drum. Install the strus and tighten the band adjusting screw sufficiently to retain the band.
23. Place a selective thickness bronze thrust washer on the rear shoulder of the stator support and retian it with petroleum jelly. If the end play was not within specification when checked prior to disassembly, prelace the washer wit one of proper thickness. Using two 5/16 inch bolts three inches long, make two alighment sutds. Cut the heads from the bolts and grind a taper on the cut end. Temporarily install the two studs opposite each other in the mounting holes of the case, being careful not to damage the large seal on the outside diameter of the pump housing, (removing the aligning studs). Install six of the seven bolts and tighten to 16-30 ft. lbs.
24. Adjust the intermediate band and install the input shaft with the long splined end inserted into the forward clutch assembly. (Tighten the square screw all the way down, then back out 1 and 1/2 turns. Hold the square screw and use a box end wrench to tighten the lock nut down.)
25. Using a dial indicator check the endplay of the input shaft, different books will give you different numbers, but .008 -.052 is ballpark. Install the seventh pump mounting bolt and tightne to 16-30 ft. lbs.
26. Install the main control valve body on the case, making sure that the levers engage the valves properly and tighten the attaching bolts to 95-125 in. lbs. Install the primary throttle vavle, rod, and the vacuum diaphragm in the case. Tighten the diaghragm attaching bolt to 12-16 ft. lbs.
27. Install a new pan gasket and the pan. Tighten the bolts to 8-12 ft. lbs.
28. Install the converter assembly.
29. Install the transmission in the vehicle.
