Does anyone know if all of the 4-speed manual transmissions in 1976 Volares were overdrive? If not, what is the best way to visually tell the difference between overdrive and non-overdrive trannies? Thanks
I have a cast iron case OD ****** in my garage right now, but most are aluminum. The 3/4 arm is flipped like Tom said. Unless it's been modified, the input bearing retainer is just over 5", like 5.125" or so. The non-ODs are smaller than 5".
There were several permutations of the a833 the OD was made in several. Cast iron short tail and long tail, and aluminum with both outputs. There are also several inputshaft bearing retainer diameters. The OD gear is where 3rd was so essentially you have a 4th gear with a 1 to 1 ratio and the .070 (something) OD gear where 3rd was. The linkage is flipped to effect the 1st, 2nd, 4th, 3rd shift. They can also be sourced from light duty GMC/Chevrolet pickups and Vans equiped with 6 cylinder engines. the length of the output shaft determines the location of the shifter in most cases although some long tail were drilled for both. They came with hurst shifters when mounted in MOPARS. The cast iron is the most durable. Being based on the 833 the same 4speed used behind the 426 Hemi and 440 they are pretty much bulletproof. The Aluminum ones were mounted behind 318's in the Volare/Aspen. Some good info here: http://www.autohobbydigest.com/a-4spd.html and http://www.slantsix.org/articles/4-speeds/ODA833fourspeed1.htm
Thanks Plym 46. I learned something today. Mopar manual trannty's of the 70's are not exactly my thing, but I had always been under the impression that the aluminum case models were almost exclusive to the feather duster, with a few of them spilling over into regular dusters.
I'm looking for one of these OD ******s to put in a 1956 Chevy p/u. Anyone know of a used one available in NorCal?
