Hi, I wanted to know if all 4l60e Transmissions are stamped with the "4L60E" on the casing?

Just curious because the trans i have taken out of my car has it stamped in the casing on the outside, and the used 1 i bought doesnt. Thanks for any insight i did a search couldnt really find anything too.

 

No, they don't all have it. Seems to depend on the year.

 

Cool thanks
