Sticky?

I would imagine some of the T-10s/T-16s were in Ford or Chrysler vehicles, don't quote me.

The rings mentioned that are on the input shaft run perpendicular to the splines, around shaft, seen here:

Re: Manual & Automatic gear ratios

IIRC, a teeny bit of the Muncie info is erratic. There never was a 2.54 1st gear. Only 2.20, 2.52 & 2.56.

Also, just an FYI-a fine spline input shaft doesn't indicate M22, nor does a fill plug on the case. 67-70 M22 were 10 spline input. 70-74 were 26 spline, so a no-ring input shaft with 10 splines can be an M20, so be careful when you try to ID M22s. The sure way is to count input shaft rings & gear teeth. If it doesn't have rings, but doesn't have 26 teeth, it's not an M22. M20's have 21 or 24.

Re: Manual & Automatic gear ratios

To add to Tommy's post. The angle of the cut on the gears is different on the M-22, resulting in the distinct sound difference of a Rockcrusher.
