Troubleshooting 700R4 transmissions
From Crankshaft Coalition Wiki
I have a 65 Corvette with an LS1 backed by a 700R4. Took it into a shop to have the door window adjusted and now it will not go into Park. Did they force something out of adjustment? How to fix? Thanks, Jim
check your shift cable. i am thinking it is a simple adjustment where your shift cable attaches to the transmission there is a lever there detach the shift cable manually put the tranny in park make sure the shifter matches and reattach shifter cable.
