    SUBJECT: SHIFT SHOCK WHEN COMING TO A STOP OR AFTER A COMPLETE STOP

    PURPOSE On certain Mirage and Mirage G4 vehicles with CVT transmissions, drivers may experience shift shock in the following conditions:

    Condition 1: When coming to a stop.
    Condition 2: After coming to a complete stop with the transmission in the D range.

    The first condition may be caused by improper timing of the torque converter clutch disengagement.

    The second condition may be due to improper CVT clutch engagement control, causing the driver to experience shift shock when the CVT clutch is re-engaged.

    This TSB instructs dealers to reprogram the CVT ECU with updated software to optimize the torque converter or CVT clutch engagement control to minimize shift shock.

    AFFECTED VEHICLES The following vehicles equipped with CVT transmissions may exhibit one or both shift shock conditions:

    Condition Model Model Year Affected VIN Range Starting VIN Affected VIN Range - Ending VIN
    1 & 2 Mirage 2014 All All
    1 & 2 Mirage 2015 All All
    2 Mirage 2017 Beginning of Production ML32A3HJ2HH020447
    2 Mirage G4 2017 Beginning of Production ML32F3FJ9HHF19303





    As I find other TSBs related to the CVT, I'll either include them in this post or as a separate post in this thread. I'll try to keep things organized here.

    SUBJECT: UPDATES TO MAINTENANCE & ASSEMBLY PROCEDURES FOR CVT F1CJB - SERVICE MANUAL REVISION

    PURPOSE This TSB updates the Automatic Transaxle section of the affected Service Manuals to update procedures for CVT F1CJB, including diagnosis, maintenance, and transaxle disassembly and reassembly. Changes have been made to procedures due to the following parts being established as service parts:
    •Oil filter
    •Torque converter
    •Plug
    •Valve body assembly
    •Plug and O-ring for CVT inspection


    This TSB covers CVT service. It's (currently) the largest file of all the TSBs, so it's got lots of detail. Here's a link to the file:
    TSB-19-23-006

    And the file is attached to this post for safe keeping. Let me know if there are any problems with either:
    1. Viewing the attachment to this post or
    2. The NHTSA link.

    Reading through it, seems it's an update to the service manual. Lots of references adding the valve body.
