a833 with 904 yoke??

I have an OD (overdrive) 833 with a 904 yolk. I am thinking thats what you have. Ceck the in and out ratios for 3rd and 4th gear. 4th is still 1:1 but 3rd in OD. They flipped the linkage plate to make it shift in the right order.

I was just going to say this , if the trans is an alum case and tail it's an OD A body 4 speed .
