Separate the MTM from the Main Housing at the 2 pry points.

Remove the MTM from the transmission housing.

Place the transmission in a horizontal position.

Clean the sealing surfaces on the transmission and Mechatronic Transmission Module (MTM) with gasket remover and a plastic scraper. Let air dry then wipe with a clean dry cloth.

Inspect threaded bolt holes for debris and clean if necessary.

Install the Rail B Engagement Tool (RR1088TR) to the Main Housing and hand tighten with 2 MTM cap screws.

Shift the Rail B Synchronizer to neutral.

Remove the Rail B Engagement Tool.

Move Rail C Sliding Clutch to Neutral and Rail D to the fore position.

Move Rail A to the Aft or rear position using a pry bar.

Move Rail A to the forward position.

Install the MTM Alignment tool (RR1116TR) into the slots of the synchronizer and sliding clutches.

Install the Confirm-Neutral Gauge (RR1117TR) onto the main housing.

Verify synchronizer and sliding clutches are in the proper positions by sliding MTM Alignment Gauge into the slots of Confirm Neutral Tool.

Note: If the gauge does not slide into the alignment tool slots, neutral is not achieved. Go to Step 4.

Using the Rail E Lever, move Rail E to Forward position.

Note: All rails in the transmission case side must be in the correct positions (A: Neutral, B: Neutral, C: Neutral, D: Forward, E: Forward).

Verify Rail E is in Forward position using the Gear Side Actuator end of the MTM Alignment tool (RR1116TR) at Shift Rail E. Rail E is in Forward position when end of gauge rests against housing with rail against notch-end of gauge.

Verify Rail A is in the forward position using the Rail A Gear Side Actuator end of the MTM Alignment Tool (RR1116TR) ensuring the end of the gauge rests against the housing with rail against the notch-end of gauge.

Move Shift Rail B in the MTM to neutral. Rail B is in neutral when the ball detent is in the notch of the Rail B yoke assembly (see image below).

Move Shift Rail C in the MTM to neutral. Rail C is in neutral when the shift inter-lock is aligned with the notches of the rail yoke assemblies (see image below).

Move Shift Rail D in the MTM to the fore position. Rail D is in the fore position when the shift inter-lock is aligned off the notches of the rail yoke assemblies (see image below).

Verify MTM shift forks are in the proper positions before installing the Confirm-Neutral Gauge (RR1117TR) into the bolt hole and onto Rail B, C, and D Shift Yokes.

Note: If the MTM Alignment Tool slots do not align with the 3 shift yokes, neutral has not been achieved. Go to Step 13.

Verify notch on Rail E is facing up.

Note: If the MTM is installed on the transmission with the notch on Rail E facing down, Fault Code 320 (SPN 5942) sets Active and the transmission will not shift out of neutral.

Verify notch on Rail A is facing up.

Note: If the MTM is installed on the transmission with the notch on Rail A facing down, Fault Code 255 (SPN 4218) sets Active and the transmission will not shift out of neutral.

Verify Rail E is in Forward Position using the Fork Side Actuator end of the MTM Alignment Tool (RR1116TR) at Shift Rail E. Rail E is in neutral when end of gauge rests against cover with rail against notch-end of gauge.

Note: If Rail E is not in Forward Position, slide rail in or out until neutral is achieved.

Verify notch on Rail A is facing up.

Note: If the MTM is installed on the transmission with the notch on Rail A facing down, Fault Code 255 (SPN 4218) sets Active and the transmission will not shift out of neutral.

Same CID picture like in above step 21, but of rail A on front side of MTM.

Verify Rail A is in neutral using the Fork Side Actuator end of the MTM Alignment Tool (RR1116TR) at Shift Rail A. Rail A is in neutral when end of gauge rests against cover with rail against notch-end of gauge.

Note: A Rail detent system is very stiff to move, and B Rail shift fork needs to be in the Neutral position before moving A Rail shaft on MTM to the neutral position.

Slide O-ring over the MTM front alignment pin on the main housing until fully seated in the groove.

Clean the sealing surfaces on the transmission and Mechatronic Transmission Module (MTM) with gasket remover and a plastic scraper. Let air dry then wipe with a clean dry cloth.

Note: 13 mm (x16), 15 mm (x4) cap screws.

Install the Release Yoke Cover.

Install 2 Release Cover 10 mm cap screws and torque to 8.8 - 10.4 Nm (6-8 lb-ft).

Install the TCM Seal on the 74-Way Harness Connector.

Align the TCM to the 74-Way Harness Connector and TCM studs, then install the TCM.

Torque the TCM 7 mm Jackscrew to 3.0-4.0 Nm (26.6-35.4 lb-in).

Install the TCM Cover over the 4 TCM studs and torque the 4 TCM Cover Nuts to 8.8-10.4 Nm (78-92 lb-in) in a criss-cross pattern.

Note: TCM Cover nuts are 10 or 13 mm.

Note: Residual air pressure in the LCA cylinder exhausts between the LCA and MTM housing when the cap screws are loosened.

Remove the 4 LCA cap screws

Remove the LCA from the MTM.

Note: LCA piston rod end is seated in the release yoke socket; pull to release rod end from socket.

Inspect the plastic socket insert in the release yoke through the LCA opening using a flashlight to verify none of the fingers are missing or damaged.

Note: If the plastic insert is damaged, replace the release yoke assembly.

Inspect LCA to determine next steps, reference images below:

• If LCA is locked in the reset position, go to Step 5 and install Linear Clutch Actuator.
• If LCA is not locked in the reset position, go to Step 2.

Place LCA push rod on a clean, flat surface. Tightly grasp LCA housing with both hands and push down on push rod to lock LCA into the reset position.

Inspect LCA to determine next steps, reference images below:

• If LCA remains locked in the reset position, go to Step 4.
• If LCA does not remain locked in the reset position, go to Step 2, repeat reset procedure.

  Note: If LCA cannot be locked into the reset position, replace LCA.

Clean all sealing surfaces on the MTM and LCA with a lint free cloth.

Insert the LCA into the MTM.
