97 model years came with 4 speed trans,
make sure you are asking for the right one
If your trans has a drain plug on the bottom
it's a 4 speed, 3 speeds are a GM TH180 and
are different, my 89 has a 3 speed, made by
GM in France

It's been a good trans, lots of miles and big tires
and a little more HP than a stock engine too
