Im looking for a trans for a friend and hes not sure what he has. Are they the same trans or is the 4l80-e electricly controlled.

His truck is a 1995 chevy 3500 6.5 auto 2wd.
Any help would be great. I looked and can't find any info or the 4l80.

Thanks

4L80-E The E stands for electronically controlled

It should have a 4l80e. Some people just leave the e off. As far as I know there is no 4l80.
