Just remember when running the Chrysler A833OD trans, that when in Overdrive, it is actually in THIRD gear. This causes some HUGE bearing speeds on the counter gear and therefore, "Looseness" inside the trans if installed after 100K miles in an old truck...The aluminum case doesn't help either when beating on 'em...
First gear ratio is like 3.09:1 and with a 4.10:1 rear gear, will be more like driving a dump truck when in first gear. If your car is a SMALL BLOCK, then you are in luck as far as bellhousings, but if it's a BB then you will have to have some machining done in order to set up the trans to the bellhousing...These things have a HUGE bearing retainer to help with the VERY high speeds the gears are turning when you are comfortable in the driver's seat looking at your tac and seeing only 2200 RPMs in the engine, when your driveshaft, transmission, and ring and pinion are reaching speeds of upwards of 10K RPMs..
Just thought I'd warn you before you install the OD Chrysler trans and back on here in about 3 weeks asking WTF? is up with the first gear and can you swap out your first gear from a regular A833 which you cannot...These transmissions are VERY wide ratio, as when they came out, Chrysler was NOT interested in stop light to stoplight..
