TMAC and Warranty have been receiving core returns and warranty claims for complete

Cause

transmissions replaced due to failures when only a partial transmission or component
replacement was necessary. This solution provides an explanation of the process for
inspecting the AMT gearbox for suitability for repair to prevent items from being
overlooked and proper repair instructions for relevant findings.
This solution is to be followed when a failure has been identified and transmission
components need to be inspected to determine the viability of repair or replacement.
Soluti

This solution should be used together with SNV19-020e.

NOTE: Duplicated or excessive labor charged to a claim due to a component failure that is missed during
initial diagnosis and teardown may be denied by warranty.

Inspection
- Operation 4311-06-02-01 Transmission Reuse or Replacement Guidelines, found under the Service tab in
Impact, should be used for guidance when inspecting the components below. This operation contains very
detailed information on what are and are not acceptable appearances, conditions and specifications for each
component.
- Individual components removed during disassembly for repair should be inspected and replaced as
necessary.
- All major areas of the transmission should be inspected prior to making repair decisions to prevent items
from being overlooked:

Several of the items listed below may already have been inspected during the diagnostic process
• Control Housing Assembly
• Main shaft and countershaft components in the main gearbox
• Input shaft, radial and/or axial play
• Rear of gearbox and range housing assembly
The PTO cover or range housing assembly should be removed as necessary to complete inspection
- If a significant amount of debris is found in the gearbox:
• Remove the range housing assembly
• Remove the lubrication pipe (lube tube) from the main shaft
Check for a buildup of metal flakes inside the main shaft that is also visible in the lubrication pipe
and on the o-rings.
- If this condition is observed the main box and oil cooler must be replaced.
- NOTE: A loose or failed high range synchronizer cone does not automatically warrant replacement of the
complete synchronizer assembly or range housing if the short gearbox is being replaced.

Repair
AS OF 26 MARCH 2019: Per SNV19-020e an eService case
is required prior to utilizing any of the information below.
The eService case MUST INCLUDE a THOROUGH
description of the initial symptoms AND findings from the
Inspection section.

The charts below outline the correct repair path for the most AMT issues encountered. Once the failure is
identified, refer to the correct description at the top of each chart for the proper components that should be
used for each repair. If the secondary (yellow) option needs to be used due to progressive damage or parts
availability, eService will advise on how to proceed.
- Green - Denotes the typical repair for the given failure. This option should be considered first.
- Yellow - Denotes the secondary option if progressive (additional) damage is found upon inspection or if
there are issues with parts availability
• NOTE: Tech support should be contacted via eService for further review if a secondary option is
required due to parts availability ONLY.

Pictures and descriptions of common replacement parts can be found below:

Basic Transmission

- Same as complete, but
does not include the CCA,
TECU, or Top Cover
Assembly & Solenoid

Short Transmission
Same as Basic, but without
Range Shift Assembly

Range Housing
Assembly

SAVED FOR FUTURE USE:

The only time pre-authorization and an eService case is required is when:
- Diagnostics at the dealership level determines that a Complete or Basic
Reman, or a New Complete Transmission is required.
- A new vehicle with low mileage (less than 50,000 mi, 80,000 km) experiences an
internal Transmission failure that may be a candidate for a New assembly as opposed
to Reman.
- A secondary repair option is required due to parts availability (See Repair section
below)
- All diagnostic options and materials have been exhausted without the root cause
identified, and additional support is needed
All other repairs to the transmission—including replacing a section of the
transmission—DO NOT require an eService case or authorization.

Warranty
The only time pre-authorization and an eService case is required is when:
- A new vehicle with low mileage (less than 50,000 mi, 80,000 km) experiences an

internal Transmission failure that may be a candidate for a New assembly as opposed
to Reman.
- A Complete Transmission has to be replaced (New OR Reman)
- A secondary repair option is required due to parts availability (See Repair section
above)
- All diagnostic options and materials have been exhausted without the root cause
identified, and additional support is needed
All other repairs to the transmission—including replacing a section of the
transmission—DO NOT require an eService case or authorization.
For any other questions or additional information, refer to the Warranty Operations
Manual, which can be found on Trucks Dealer Portal (TDP).
