...4l60-e or a 4 speed 4l80-e? i was looking at putting some new parts on my truck and it would really help if i could find out what transmissionn is inn my truck. Thankyou
Look in the glove box there is a series of 3 digit codes. If it shows a M30 or MD8anywhere on that label it is a 4L60/E. If it has an MT1 it is the 4l80E.
