Swapping a A833OD for a A833
I went the other direction, A833 to OD A833.
I even had the OD bearing retainer turned down so I could swap a larger retainer on to the A833, so I can easily swap trans.
The plan was use the OD for long cross country trips, the other for around town.
I haven't had the urge or need to swap the OD back out.
Imo, it's the better all around trans, all in how you shift it. It rips the treads off the tires in 1st, 2nd is fun and great for downshifting from 3rd or 4th, third is ye 'ol 4th, and OD is fantastic on the highway or country roads and for gas mileage and distance and hearing music or my co-pilot talking.
And yes, the OD can take the horsepower.
Mine is the cast iron OD, but you can have a steel bushing put in the aluminum counter shaft hole. I may have some terms there incorrect.
