Transmission code
 

Good day, can you point me in the right direction.

I want to change all my oils this weekend (engine, diffs, transfer case and transmission) but Im getting a run around from parts places. They want to know what transmission I have...is it chevy made, Mitsubishi, or Hyundai.

Only one that they have in stock is :
4 SPD TRANS - 4L60-E TRANS - 16 BOLT DEEP PAN


Where do i find transmission code? Is it printed on the housing, and if so...where?

Thank you

L460e standard depth.
