I just read that in 1975 A-833 overdrives were first made for A bodies and that in that same year all A/B body non-overdrive A-833's were discontinued.

This would seem to mean that ANY 1976 and up A-833 for A bodies or B bodies is an overdrive transmission. (Don't know where B ends and E begins.)

Am I missing something?

Thanks

PS. What is a G/RG block?

G/RG Block is a slant six... 'G' is a 170 (short deck)
RG- is a 198/225 (tall deck)


E is any 1970-1974 Barracuda/Challenger...

B is Chargers, Satellites, Coronets, 78-79 Magnum, 68-75 Road Runner,
Belverdere, GTX, 77-78 Monaco (not royal monaco), 75-79 cordoba, 75-78 Fury

Only a few are going to have a 4 speed transmission as the muscle cars waved bye bye in 1974... and most were equipped as family barges (i.e 318/A904... or 400/727)...

Yes, any 1976-1980 A-833 for Dart/Valiant variants, and Aspen Volare variants will be OD...

Thanks. Interesting. I just talked to a car-part.com dealer who has a 1976 Aspen 4 speed. He says it is cast iron and NOT overdrive. Should I grab it knowing for certain it IS overdrive?

Thanks

a couple of possibilities; The trans has been swapped in the last 32 years which means it could be either OD or non OD; I've had both versions of the cast iron transmission. The OD came in both alum and C.I. (I had a cast iron 833 OD out of an early 80s van)

unless you can visually inspect it and see if it's stock, and the front shift toggle is pointing 'down' and the reverse and 1-2 shift toggles are pointing up when bolted to the mechanism... then it could be anything swapped under there... I just freaked out a chevy guy at the shop with my '67...
it still has the column shift lever for the A904... but I swapped in an A-230... and have a 3spd floor shifter... I just told him I have a 3-spd car... he's still trying to figure whether I meant 3spd manual or auto....

pictures and a saturday drive are 9/10ths of the fun of getting the right part to do the job...

If has a cast iron main case and tailhousing, odds are very good it is not an O.D. A-833. By '77 both the main case and tailhousing were aluminum in all F-bodies, so while a '76 F-body (Aspen/Volare) could still use cast iron pieces, it still must be the O.D. version if it's original. As mentioned, it could have been changed at ant time, too.

Ask the seller to get the characters off the raised pad on the pass. side of the main case- that will tell you what it originally came in and if it's original to the car.

Thanks Pink. I used to drive a 10 year old pink DeSoto convertible with a black top. (Fully internally-balanced flat top six.)
