3 Speed Manual Trans Ratios

[Justin Jones]

Hello, I've done some researching on here and that's probably where I've found the most answers. But we've got a '69 GMC with a 292 L6 with a 3.73 rear end.

What transmission ratios does it more than likely have?

From what I've seen the: 1st 2.85, 2nd 1.68, 3rd 1.00 and Rev 2.95 ratios seem to be the most common. Thanks.

That would be a column shifted Saginaw three speed. The ratios are 1st 2.85, 2nd 1.68, 3rd 1.00 and Rev 2.95, as you have suggested.

Oh, thanks, I forgot to mention it being column shifted.
