I thought I remember reading if a t10 has 2 grooves in the main shaft, that's an indication of close ratio gears. Does anyone know if this correct? I've seen them with one groove and 2.

Hi Dave,
Looks like you need to open this up and inspeçt,then count teeth to know exàct geàr ràtios.Easy to do if already out as pictured.Is it an aluminium case?

Cast iron. Going to look at it. Not in hand at the moment. I thought the number of grooves helped indicate different sets of gears.

My "M" trans has 3 grooves, very thin. B-W # T-10M-16.
Also have an "L" input, it has 1 groove. Ford C3AZ-7017-G T-10L-16
You could have the "H" ratio, with 2.73/2.04/1.50/1.1 R2.80
