What Trans Do I Have?

[FSJMike]

Went to get a trans filter kit for my 95 K2500 6.5L Burb tonight & they said there were two different tranny's for it! 4L60e & 4L80e. How do I find out which one I have?

Thanks!!

There are a bunch of RPO codes on a tag in the glove box, if M30 is listed then you have the 4L60-E, if MT1 is listed then you have the 4L80-E.

Cool, thanks! I saw that tag when I was looking at the manual, but couldn't decipher it.

Thanks again!
