1997 chevy k1500 transmission

A 4L60E has 16 pan bolts and a 4L80E has 17 pan bolts

First off the difference in a c and a k series truck is that the c is 4x2 and the k is a 4x4. You will have a 4l60e in your c/k1500. When you get into the c/k2500 or c./k3500 you will start to get into the 4l80e. It is like this because the 2500 and the 3500 are bigger trucks. I am 99.99% sure that you will have a 4l60e, because that is what i have in my truck and i have a 1997 chevy k1500 5.7 l v8.

It should be the 4l60e , i believe the c-series were the heavy duty models with the larger rear axle and the 4l80e tranny. but to be certain , it's stamped on the passenger side i believe , towards the front (on the bell-housing or right behind on the gear box but definately on the pass. side. note: you may have to remove the heat shield in order to see it . it's that little cover ( held by 2 small 10mm bolts ) that reflect the heat from the catylitic convertor but its simple...

Hi my four wheel drive engages but dont seem to be in 4 wheel drive the axles turn but i could stop the wheels by hand when vehicle is lifted?
