Warranty Information:
Allison service outlets shall submit an AWAARE claim for each transmission serial number completed under the
Field Action.
In each Field Action AWAARE claim, any parts, labor, or travel cost beyond the scope of the Field Action letter
but necessitated by the Field Action must be explained and justified in the claim Narrative–otherwise they will be
deducted from the claim.
Example: Damage to the internal wiring harness u-channel, resulting from removal to perform the Field Action.
Replacement of the internal wiring harness is beyond Field Action scope, but is justified because the damage
occurred only as a result of performing the Field Action. Replacement of the internal wiring harness must be
explained and justified in the AWAARE Claim Narrative.
Work unrelated to the scope of the Field Action must have a separate dedicated AWAARE claim submitted.
Example: The scope of the Field Action is limited to the group 16 control valve assembly. As part of the service
work, a leaking output seal is discovered and warrantable. The output seal repair should be filed as a separate
AWAARE claim.
Allison service outlets must follow the published Allison Transmission current labor time guide for work performed
when adding any additional charges.

NOTE: If a Customer requests reimbursement for a “Customer paid Main Regulator Valve replacement”
on a transmission listed in Table 1 of this Field Action, the authorized Allison service outlet that performed
the repair may request reimbursement for these repairs via AWAARE. The service outlet shall follow all
applicable procedures outlined in the above Field Action Letter and attach the original customer paid
invoice to the AWAARE claim. Total reimbursement to the service outlet will not exceed the standard
labor and parts identified in Field Action 2020FA01. A Claim Type 4 reimbursement from Allison shall
be credited back to the customer from the authorized Allison service outlet. Customer reimbursement
credit documents must be retained for Allison audit.

NOTE: If a Customer believes they have experienced an unacceptable failure rate within their fleet and
requests proactive replacement of the transmission main valve body, see Field Action Letter 2020FA02 –
Special Coverage for TIDB Main Regulator Valve P/N 29563501 – Proactive.

Claim Submittal Information:
Approved authorized Allison service outlets must submit work performed per this Field Action as outlined in Table 7,
Table 8, Table 9, or Table 10. This Global Customer Satisfaction Field Action initiative remains active until five
years from the in-service date of the vehicle. Submit all 2020FA01 claims as Claim Type 04.

This is a Global Customer Satisfaction Field Action. The intent is that the customer will bring their vehicle to an
authorized Allison service outlet for the applicable repairs. If the authorized Allison service outlet determines the
overall cost to Allison would be less if the repairs were performed at the customer location, a travel expense will be
allowed. However, this justification must be clearly explained on the claim.
Allison service outlets shall submit an AWAARE claim for each transmission serial number completed under the
Field Action.
In each Field Action AWAARE claim, any parts, labor, or travel cost beyond the scope of the Field Action letter
but necessitated by the Field Action must be explained and justified in the claim Narrative–otherwise they will be
deducted from the claim.
