I didn't realize the od's had a different pattern on the shifter?!

The 833 O.D doesn't have a different shift pattern in it, the shift arms are reverse on the 3-4 gear selector so the shift patter stays the same,1-2,2-3,3(direct)-4(O.D.) not backwards or upside down I have several NP 833 O.D., one out of a F or A body and one out of a van, same or similar to the B-E bodys I'm told. I'm planning on using the short tailshaft trans in my 1969 Dart GTS 383 4 speed car



yup....the lever was flipped at the factory, so you had 1-2-DIRECT-OD

gear ratios are 3.09 1st, 1.67 2nd, 1.00 3rd .73 4th

it's a nice spread (about the same as a GM TH700R4) if you build an engine with a nice flat torque curve, it would work great with the A833OD. with that gear spread and the low first gear, a 3.23 or 3.55 is an ideal rear end ratio, which nets you a 10:1 to 11:1 overall first gear ratio, and a 2.36-2.59 4th gear ratio (which yields a 2000-2250 RPM cruise at 70mph with 27" tall tires like 255/60R15's)

but you have to plan for the gear spread. for me, that means slightly shorter duration, wider LSA cam, which sacrafices a bit of peak torque for a flatter torque curve where hopefully 90% of peak torque is available from say 2000-5000 RPM....

I have one from the factory in my slant 6 duster with 3.23's and 25" tall tires. great tranny, gear spread doesn't bother me. would be an awesome tranny behind a mild magnum headed 318 or 360, or even a stockish 5.7L hemi.
mine is an early tranny, full cast iron case.
