[QUOTE=Rich Silvestris;1576285977]FourSpeed,
. "By monitoring the engine parameters and the 1st gear switch, the ECM can determine what gear the vehicle is in. This will cause the ECM to keep the overdrive relay de-energized, if the vehicle is is 1st gear except during deceleration. . . . " So if you shift into 1st without stopping and don't apply the throttle right away, the OD stays on until you do.
Exactly. The O/D will remain on (energized), if not turned off manually, and will be de-energized in first gear under accelleration and energize itself again automatically when you shift to second gear. We do agree.

The overdrive on my vette no longer works. I had to replace it(had no reverse) with one of those overdrives that uses a cable, my car though is the one with electronic operated overdrive. So I just use it as a manual now with no top 3 gears.
Hope this made sense..
