1999 Chevy Express 3500. I need to know if I have a 4L60 or 4L80. Can't find anything under the hood. Part store could not tell me through VIN #. How can I find out? Please help. Thanks.

Look at the shape and the number of bolts in the transmission's pan.

Unsure at this time. Due to recent storm I cannot crawl under to check. Do you know how many for each?

Thank you. I think it's the 4L80 because it's a one ton van with a 5.7 liter vortek. Do you agree? I can't get under there until tomorrow night and I have to order a flywheel.

There is a sticker that has a bunch of numbers and letters on it. I believe it is on either the driver's or passengers door jam near the latch. The sticker basically tells you what options the vehicle is equipped with.

M30 = 4L60E
MT1 = 4L80E

Looks something like this:

thank you for all your help. It was a 4l80e I had to get under and count the 17 bolts as the jamb sticker was washed out
