All 4L60E (700E) units from 1995-1996 may need a ground wire
added during installation! Call us and ask for Reese (800-622-4836)

*Note: 1993 was a cross-over year. If your 1993 has a T.V. cable
you have a 700 (4L60). This happens quite often.

  • To find OEM codes for 4L60E with removable bell, look
    on the under side of transmission between extension
    housing and the transmission. (See Picture)
  • To find OEM codes for 4L60E non-removable bell, look
    on the passenger side rear near the extension housing.
    (See Picture)
  • When 2nd is manually selected the transmission starts in 2nd gear. This is a normal condition and no further attention is needed.
