Ok here we go again.

Looking through more receipts from Andial and found they put a new transmission in the car in '91.

How can I ID which tranny it is? I'm hoping it's a later model.

Thanks!

Bottom of the trans, from driver side to passenger side on a flat spot sort of below the axles, G28/xx etc.

I found this for whom ever might need it

Damn... g28/03 1979..... oh well...

Ricouse

hello, my question is, can mount a automatic transmission of a 928 1979 a 928 1982?
if I read the 1979 model possesses a A22.02 and models of 1982 one A22.01, what is the difference between the 2 gearboxes?

Vilhuer

Not much difference between A22.01 and .02. Just different gearing IIRR. Should be direct replacement.

Ricouse

Thank for you response.
My box is down about 28 of my 1982 and waiting to be repaired, I found a box of 1979 but what can I install it? We say yes, although different from professional there are no major differences that make this not be possible!
