The following policies are ACS's Warranty Policies, Terms, and Conditions that apply to all ACS services.

ACS does not offer refunds for:

• Repair and Rebuild Services Our technicians dedicate parts and man-hours based on your description and/or Diagnostic Trouble Codes (DTCs) provided. ACS specializes in Testing and Repairing issues you identify from your diagnosis — we do not diagnose.
• Programming / Cloning Services When we program or clone an ECU, we're dedicating licensed software, specialized tools, and expert technician time to customize your specific unit. Since this work is permanently tied to your module and cannot be reversed, refunds are not available once programming or cloning has been performed.
• Testing Services Our testing process involves carefully inspecting and analyzing your ECU using advanced diagnostic equipment and skilled technician time. Even if no fault is found, the resources, time, and effort spent in testing your unit are real and significant, so unfortunately, test fees are non-refundable.
• Shipping and Handling Shipping and handling fees cover the cost of packing, preparing, and physically moving your unit between you and our shop. Once your shipment has been processed and picked up by a carrier, those costs are completed services, which makes shipping and handling non-refundable.

Replacement Unit Return Conditions (for full refund)

• Return within 14 days.
• Plastic Sealing and Warranty Stickers must be intact.
• Unit must not be installed or tampered with.

If the conditions are not met; a 60% Restocking Fee applies. Misdiagnosed returns will be subject to a 60% Restocking Fee.

Required Before Sending Your Unit:

• Scan the ECU (Electronic Control Unit).
• Complete a Service Form.
• Remove all aftermarket performance tunes — ACS is not responsible for their loss.

Service Turnaround Time

• Repair and Rebuild (excluding Allison A50 and T14) : 3–5 Business Days
• Remanufacture: 3–5 Business Days
• Programming / Cloning: 1–5 Business Days
• Harness Restoration: 10-15 Business Days

NOTE Service begins only after all required information and the ECU are received. We aim to meet these deadlines, but delays may occur beyond our control. Plan accordingly.

Test Fee 

• Gas:  $88.88
• Light/Medium Duty Diesel: $148.88–$248.88
• Heavy Duty Diesel: $248.88–$448.88 

If prepaid service exceeds the actual fee, the balance will be refunded.

ACS is not responsible for Shipping Costs (unless otherwise specified). Please note that ACS is not responsible for any issues or delays related to shipping, as all shipments are handled by third-party carriers. Customers are responsible for shipping insurance. ACS is not responsible for lost or damaged shipments.

• Free ground shipping is available for select purchases within the 48 contiguous U.S. states.
• International shipping must be arranged by the customer with prepaid UPS labels.
• Return labels are not provided for Warranty or Refund Returns.
