Transmission ID help

[warndogg]

I have a 2006 Yukon Denali AWD that needs a new new transmission. M32 RPO code. 4L65e right?

Was looking at some re-maned on ebay but the seller is telling me I might have a 4L70e. Is that possible?

Is that possible?

No. Not if your RPO code for the trans is M32 and it's original.

Do you have a turbine speed sensor in your current transmission?
