727 Overdrive

My trans guy--who is in to mopars--says mopar doesn't make a good o.d. trans. For everything involved you do seem better off with a gm o.d. trans

Either that or just grin and bear those 4000+ rpms runs on the freeways, lol.

Mopar sold many cars with 3.55 gears back in the 70+ mph days. Hear stories from my father friends how traffic used to go 80 to 90 mph back in the late 60's early 70's. Nobody had o.d trans either. This was way back around 1980 I heard about it so it wasn't like they were old back then and foggy on their memories.

Yeah people also brought new cars before the car was 5 years old!
