MD2 76-87 TRANSMISSION,3-SPD AUTO (THM180C)
Izuzu - used in Chevy Chevettes and other Izuzu's from 76-87.
I don't have any personal experience with this trans but I do
know the THM125C.
I can't imagine any similarities other than one end bolts to the
engine and the other to the subframe.
You may be able to get a manual on CD from

They mounted it (THM180C) in different ways:

1. Top Mount
2. Bottom Mount

But, when I look at a 1993 Chevrolet Corsica, with 2.2L motor, this
transmission appeared to be a normal bottom mount style...and may have
same config as 125C tranny.

I was thinking of putting an Iron Duke Motor (2.5L) into this
Chevrolet Corsica...I think it will work, but I DON"T understand why a
vacuum line goes into this transmission?

>know the THM125C.

Btw, on this tranny, what's the mim shop tools needed to do it?

thanks,
