GMPT stands for General Motors Powertrain and 4l60e is the type of tranny. If they only changed the internals and re-used the stock case I don't believe the part numbers on it are going to help.

thanks i kno what a 4l60e not trying to be rude or anything u im trying to figure out if its trully aftermarket or not but i guess the gmpt indicates that it is not

The 4l60e is the electric version of the old 700r4.. Nothing to write home about...

The 4L60E is an electronic version of the 700-R4. It breaks down as follows:

4 - Four forward speeds
L - Longitudinal mount
60 - Series of transmission
E - Electronic control

So OP did you find any numbers or badges besides the stock ones?
