Re: 4L60E rebuild, no 3rd gear
Okay,
I took the tranny off and remove the input drum. I got a different input drum (used but tested one, whatever that means, with all new seals already installed), disassembled and reassembled the new drum with new sprag, tested and this time there was no air leak on any of the clutch packs when I use 40psi air pressure. I did not touch anything else in tanny since I though there is no need for it.
Pu things back together and put the tranny in the truck with fresh fluid, no 3rd!!!
This time, it is shifting hard from 1st to second while before, the shift from 1st to 2nd was very smooth.
This seemed very clear process but now it feels so confusing! What am I missing?
Is there an illustrated reference book for 4L60e? Could it be wiring, that I am connecting the wires wrong on transfer case? But the transfer case is not suppose to be engaged in 2wd mode??!!
Thanks
