Manual & Automatic gear ratios & other trans. info

Post by Doober » Sat Apr 05, 2008 9:10 am

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:

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.

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.
