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:

Year Make Model Engine Size

The VIN 8th digit is the “Engine ID” and the 10th digit is the “Year” (1980=A, H=1987, J=1988, N=1992)

604 (41TE)

NOTE** This transmission is NOT sold as a carry-out unit. It must be purchased & installed by a qualifying shop!! Contact us for a shop near you.

NOTE** This transmission is controlled entirely by a computer. A bad fuse, thermostat, vacuum connection, or electrical connection can cause a “Limp Mode” condition. You MUST scan the transmission scan port (not the normal vehicle computer port) for proper diagnosis. Use the Snap-On Chrysler II adapter for this procedure.

1988-91 There is a vehicle speed sensor on right right axle housing. (See Picture)

1992-Up Is there a vehicle speed sensor in the right axle housing? YES-Early NO-Late

1993-Up The following models should have a 606 transmission: Concorde, Intrepid, LHS, New Yorker, Eagle Vision.

1996-Up Does transmission have a single non-removable 8-pin connector (pointing up) or are there two switches located on the front of the transmsission just above the pan rail? (See Pictures)  Manual Lever Position Sensor (MLPS) pins could be flat or round.

This transmission must have at least a VERSION 10 Controller (use scanner to determine the Version).

1988-1991 Must get new controller if not Version 10!!!

1992-Up If your Controller tests OK and it is PART #AR4686606, or it is a VERSION 10, you may use your existing controller; if not you must replace the controller.

NOTE** The vehicle’s Clutch Volume Index (CVI) must be QUICKLY learned with a current version scanner!! Failure to do so will result in the same condition the old transmission had & could destroy the rebuilt unit immediately.

1988-1992 AA body vehicles (LeBaron-Without a body control module, Spirit and Acclaim) – If a new controller is installed you must use the bulletin sent with the transmission referring to the modification to the controller to prevent improper 4/3-3/4 shifts.

2007-Up 62TE 6 speed. You could also have a 604 with a prindle switch & EPC plug
