I have a 3 speed with an overdrive out of an early to mid 80's chevy pick-up. It is a saginaw, but has an aluminum housing and a funky bolt-pattern on the front. I need to find out what the gear ratios are. A mechanic told me that there are two of these and they are identified by the distance between the shafts (in millimeters). Any help would be appreciated.

Found out that it's actually a chrysler tranny -A833 and ratios are:
1ST - 3.09 to 1
2ND - 1.67 to 1
3RD - 1.00 to 1
OD - 0.73 to 1
