I am curious if a 1991 suburban 3/4ton might have the 4L60E?
I'm pretty sure they came with the 4L80 in 91.
it would have to be a 4l80E or 700 the 4l60E was not offered until 93
it's possible, check the glove box. MT1 is a 4l80E and M30 is a 4l60E.
A '91 2500 series Sub should have the 4L80E.
My '91 V2500 has the 4L80E and 241C.
Separate names with a comma.
