1976 three on the tree question

Yeah the A833od is a 4-speed....
in as much as all four gears are in the main box, and all 4 gears can be shifted by the one stick.
But with a V-8, you can't drive it like a 4-speed. If you power shift , or just shock that tiny M/S gear; it just explodes. Overdrive is strictly for cruising in. Therefore I call it a 3+1, which is way more accurate than calling it a 4-speed.
I blew three of them up before I figured enough was enough. One of them also took out the Input gear out, which pretty much trashed the whole box.
I got lots of spare parts, except of course the M/S od gear...... lol.

but yeah, I would run it behind a slanty.
And also behind a 318 but if I did, I would put some kind of interlock on it to remind me to ease into overdrive.
I once put a GVod behind that box, for seven well-spaced and usable ratios. That combo made great fuel-mileage with a final drive ratio of 1.97, lol. for 85mph =2100rpm
