After you finish passing, just let off the gas an instant and you are automatically back in overdrive! Coming to a long downhill? Floor the gas to kickdown, pull out the lockout handle, and proceed down the hill in direct high with better engine braking. Cars with the Borg-Warner O/D usually had 4.11 or so gears. With a ratio of (I think) .72 in O/D, the effective axle ratio became 2.95 instead of 4.11. If you didn't like to shift around town, you just left the trans in second in slow traffic. If/when you got above 27 MPH just let off the gas for an instant and you were in overdrive second, good for 40-50 MPH.
That ol' overdrive had a lot going for it!
Right, i know from experience and i wont be switching back. The T5 is worlds apart from the merc

The reason I used the S10 transmission at the time, it was free for towing off the entire truck. I since bought a Camaro transmission but have no reason to take it apart.right now

The lincoln overdrive to me is just a doner for the gear set. Last fall there was a local hoarders place getting scraped and pretty much everything was junk but digging inside the remains of a 49 ford panel truck was a lincoln overdrive. I bought it from the scrapman and took it apart with a sledgehammer. I did manage to salvage a 25 tooth gear set and a U joint. As bad as the outside was i didnt think there would be anything left inside. The overdrive unit was junk.
I took a 50 olds 3 speed apart the same way to salvage the output shaft. The rest was junk. A careful smack in the right spot with a 8lb hammer and they split open like a egg. Saves alot of time and cussing getting a frozen junk transmission apart
