Alright I have 8 ZD-9s on the way. Hoping some penetrating oil soaking over night and a heat cycle an they'll come out with ease for me! On a side note does anyone know if there's a certain time the torque converter is suppose to lock in on an e4od? Just realized that what I thought was 3-4 shift is actually my TC locking last in 4th. Still shifts good an runs fine just seems to shift early an TC comes in too late. Thanks again everyone!!

Also now realize what I thought was the TC locking right after 3rd gear but no it actually just almost instantly shifts to 4th!?..I put a switch in to lock or unlock the TC to confirm this theory. Trans seems good maybe sensor??

Fix 1 thing at a time. Then onto next...makes following thread much easier than bouncing around.
