GM 88996640 Front Bellhousing 7/8 Thread Fitting Kit (Includes Both Fittings)

This is a genuine GM (AC Delco) service replacement kit. This kit will include both of the large style (7/8 thread) bellhousing fittings that thread into 2003-2007 transmission housings. The portion of the fitting that engages the cooler lines is designed for 2001-2002 cooler lines only.

Only one part number is required per truck.

Fitment Notes: 2003-Newer Duramax diesel pickups. There was a change over in mid-year 2003, so if have a 2003 you will need to visually check to see which fittings you have.

If your truck is 2004-2016 you need fitting number 88996645.
