I helped my dump truck eat another E4OD. Well…
I do plan on attempting to rebuild one of these finicky slushboxes… since I now have two fubarded ones… but believe me when I say that’s not very high up the priority list… might not even be on the priority list.
My '89 came with a 3 speed E4OD.
Swapped it to a ZF5.
Was a PIA, but knowing it's a rock solid drive train is priceless.
Have only rebuilt one C6, wasn't too bad, except locating the snap ring in front of the rear planetary that keeps the output shaft from sliding out.
The only two models they ever made those for were c6 and E4OD, and they quit making spare parts 20 years ago.
Mine had become brittle and broke on removal.
Found a shop in CA that sent me all he had left for postage.
Let me know if you need one, I can't just throw them away...lol
That c6 is working away on a box truck.
