First gen transmission question

[rx761]

Will a tranny out of a 84 fit on a 81? They are both 12a's. Thanks

Yes, 81-85 are interchangable. '79 will fit but the shifter is in a slightly different spot.

However, if you are using 5th gear, 81-83 ratio is .825 and 84-85 is .758. That typically makes the 81-83 better for racing applications.

Ok, thanks for the info.
