No: TSB−17−23−003
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.

Hold up is this a recall or just a new manual for service techs for fixing the CVT7?

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