Thanks Rotorwrench, I agree that the OD shall engage even if the car is off the ground.
As I said, all tests described in the shop manual have been successfully performed, except ignition grounding contacts inside the solenoid.
The engine doesn't stop when I press the kickdown switch.
Do you think I shall purchase a new solenoid ?
There is no lock out switch on my OD.
FYI, balk ring is new as well as planetary, rollers and rollers cage and spring.
