Warranty Policy – Gearshift Auto Parts

At Gearshift Auto Parts, we specialize in supplying quality used engines, transmissions, and auto parts. While every effort is made to ensure reliability, used automotive components are subject to wear. This warranty defines the scope, limitations, and conditions under which coverage may apply.

By purchasing from Gearshift Auto Parts, you acknowledge and agree to all terms outlined below.

Warranty Notification Requirement

To be considered for warranty coverage, the buyer must notify Gearshift Auto Parts in writing via email within thirty (30) days of delivery of the auto part. Failure to provide timely written notice will void the warranty.

Warranty Terms & Conditions

By completing a purchase, the buyer expressly agrees to the following legally binding terms:

• Mileage is not guaranteed or warranted. Mileage information is provided by manufacturers, prior owners, or third-party yards and cannot be independently verified. Any mileage discussed verbally by sales agents is non-binding and not guaranteed.
• Labor costs are not covered under any circumstances, including diagnostics, installation, removal, teardown, or shop fees.
• Commercial, industrial, fleet, off-road, racing, abusive, or heavy-duty use voids the warranty.
• All warranty claims require written notification prior to any repair, removal, or disassembly. Unauthorized repairs automatically void the warranty.
• All warranty claims must be supported with verifiable documentation, including installation and diagnostic records from a qualified automotive facility.
• Gearshift Auto Parts makes every effort to inspect and make sure the part is clean before it ships but makes no warranty or guarantee regarding the appearance.
• Engine or transmission must be installed, AND warranty automatically is activated from the day it is received by the customer or delivered to the customer mentioned address OR ALL WARRANTIES WILL BE VOIDED.
• OEM auto parts are interchangeable with multiple years, makes and models, which means the same part is an exact fit for multiple makes and models as determined by OEM standards. We guarantee the part we sell to fit your vehicle.
• Any engine and transmission returned not in the same assembled condition as it was received will not be refunded under any situations. If the engine or transmission is disassembled in any way without our express written authorization, it will void the warranty.
• The Buyer/purchaser hereby agrees to pay all costs associated with examination, diagnosis, testing, and repair if failure has not occurred or has happened due to improper installation or any other reason outside the warranty scope herein. We reserve the right to inspect warranty claims that are related to transmissions, engines, axle assemblies, carriers or any other part before removal or return. Furthermore, we reserve the right to make the final decision of the warranted parts failure; our decision shall determine the validity of the warranty claim.
• This warranty coverage ends after one replacement of the part described on the original invoice.
• All cooling lines must be flushed of foreign materials. Vehicles which have Gearshift Auto Parts engines and transmissions installed must have proper capacity cooling systems and be in good working condition.
• In the event that a part is faulty or not functioning as claimed by you, Gearshift Auto Parts may request a mechanical report detailing the reasons, causes, or specific parts preventing proper operation. Failure to provide such a report will be considered a violation of company policy, as the authenticity of the claim cannot be validated without it. Consequently, Gearshift Auto Parts reserves the right to determine the appropriate course of action, given your non-compliance with the basic requirements outlined in Gearshift Auto Part’s terms and conditions.
• If a package, shipment, or part arrives damaged (e.g., broken or cracked), the customer must retain the item in its original packaging and promptly contact Gearshift Auto Parts via phone or email. The issue should be briefly described, and a ticket must be raised and submitted along with photographs of the damaged package, as instructed by a Gearshift Auto Parts authorized representative. Failure to follow these steps may hinder Gearshift Auto Parts ability to resolve the issue efficiently. Additionally, Gearshift Auto Parts must be notified of such incidents within 24 hours of receiving the package, shipment, or part. Failure to do so may invalidate the warranty, refund, or replacement options.

Warranty Coverage

• Engine warranty is limited to the long block that includes defects in the heads, blocks, crankshafts, pistons, rockers, camshafts and oil pumps. Parts external to the cylinder head(s) and cylinder block – the distributor, fuel pump, and carburettor – are not under warranty. These are left for the convenience of the installer only. New radiator and oil cooler, timing belt, thermostat, oil seals, and gaskets must be installed before engine installation. New oil filter must be installed and engine oil must be replaced to manufacturer’s suggested level. We do not guarantee against oil leaks. We do not guarantee against failure of other accessories installed on the new engine from the buyer’s old engine. It is the buyer’s responsibility to ensure the function of any and all accessories used on Gearshift Auto Parts engine. It is the buyer’s responsibility to ensure the transmission of the vehicle is functioning properly so it will not damage the engine. If the transmission is malfunctioning and damages the engine all warranties are voided. All engines and cylinder heads have heat tabs installed on them. If the vehicle begins to get hot the buyer must stop the vehicle and turn off the engine immediately. Failure to stop the vehicle and shut off the engine immediately will result in the engine overheating and will void all warranties. If the centre of the heat tab is melted out, or the heat tab is missing or the engine is run hot under any conditions the warranty is void. Please check your parts for heat tabs before return. Receipts required for all warranty claims.
• We do not warranty oil leaks/impairment on engines or transmissions due to non-replaced seals, gaskets or filters.
• Transmission Warranty: The installer is responsible to reprogram any modules, replace or flush the radiator, transmission fluid cooling lines and transmission oil cooler. Proper operation of the cooling and electrical system should be checked when installing products that could be affected by these systems. Recommended installation procedures that we provide should be followed by the installer to maintain warranty coverage. Failure to install a new filter (A.T. only), improper detent adjustment, broken front pump, low-level fluids or improper installation voids all warranties.

Odometer & Mileage Disclosure
