Does not work with manual transmissions 30 day exchange-only warranty DETAILS This has never been in a vehicle. It was taken from an assembly line leftover automatic transmission console, so it is in excellent condition. It is GM part number 84169753 or 84010417. It lists for $90+ on the GM sites.

We also have many other GM console parts available for purchase. Please email before purchasing, if you have questions.
