I could not find a c5 tranny for my 84 4x4 so I took every bodies advice and put a c-4 tranny in the truck. To my surprise, nothing happened but grinding when I started the truck.
Thinking I did not get the torque converter set correctly, I immediately checked but it was ok. After pulling my hair for a couple of days, I finally discovered the pilot shafts were different between the c4 and c5. The c-4 will not engage correctly in the c-5 torque converter, and the c5 pilot shaft will not fit into the c-4. I can not use the c-4 torque converter because the 84 flywheel will only accept a 3/4 pilot shaft(c5) and the c4 has an 1 3/4" pilot shaft.
difference c4 c5
thickness .793" .846"
length 10.06" 9.75"
splines dual 24 26 on TQ end, 24 on C5 end.
Any Suggestions anyone, please help
