Transmission Identifications

[xczar]

Hello, ......... I tried doing a few searches for trans id`s here with no luck. I am the original owner of a 1997 GMC YUKON 2-door/4WD. I checked the trans pan bolt pattern, it has 16 bolts. But, need to confirm which trans I have. 4L60? 4L80?
Reason for this, evidently, to get the correct 02 sensor, I need the correct trans ID. I pulled a OBD: P0155 code and need to get the damn engine light turned off.

Thanks for any info you may have?

You should have the 4l60. A universal o2 sensor would work fine just would hav to pin it to your plug but that's super easy
