This guide will help you to identify your transmission and assemble the information needed to order a replacement. As you go through the guide, the information we need to process your order will be printed in RED. Please read the entire guide before ordering. Thank you.


To properly identify your transmission the following information is needed:

1983 Camaro & Firebird, 1984-Up All, need first 4 digits (numbers and letters) from ID Tag. A paper tag may also be present on the driver side top of the bell. (See Pictures)

1993-Up SHOULD be the electronic 4L60E. If it is a 4L60E it should have a large round electrical connector on right (passenger) side and should not have a T.V. cable!! SEE 4L60E SECTION BELOW!!
