4L60e & 4L65e torque converters..?
Yes, as long as you are comparing '98 or later 4L60E with a 300mm input shaft (all '98+ for LS engine are 300mm). There are no external or electrical differences.
Since there are some differences after 2006, affecting both 4L60E and 4L65E, tell us exactly what you are considering.
As Carlsonauto says, your 3-4 clutch has failed which is a common problem with these transmissions. Time to check your warranty.
