Article I · Coverage Duration

How long is the warranty?

Coverage length depends on the transmission's manufacturing era — newer units carry longer warranties because their components have aged less. Some premium parts qualify for up to 36 months of coverage.

Tier 01
Made in 1990 or earlier:
1
Month
Tier 02
Made from 1991 to 2000:
3
Months
Tier 03
Made from 2001 to 2025:
6
Months
Tier 04 · Premium
Some parts are eligible for a warranty of up to
36
Months
Tier assignment is determined by the transmission's model year. Premium 36-month coverage is offered on select late-model, low-mileage units — your specialist will confirm the exact term at quote time.
Article II · Return Terms & Conditions

The fine print, without the fine print.

Two clauses every buyer should read before signing for delivery. Plain language, no surprises.

§ A · Cancellations
Clause A

Order Cancellations Policy

You can cancel your order within 24 hours of payment and get a full refund.

After 24 hours, we begin preparing your transmission for shipment. If you cancel after this time, the following charges will apply:

  • 20% restocking fee
  • Round-trip shipping cost, if your part is already shipped
§ B · 30-Day Window
Clause B

30-Day Return Window

Let us know about any visible damage or issues within 30 days of delivery. We can't take returns after 30 days.

Please note: If you send the transmission back even though it was delivered in good shape, it counts as a canceled order. In that case, our regular cancellation fees will apply.

Article III · Warranty Terms & Conditions

Five pillars of your coverage.

What you're entitled to under the warranty, broken into five operating principles.

Pillar 01 · Window

30-Day Installation Window

Install your transmission within 30 days of the invoice date to keep your return and warranty valid. If the transmission sits too long, air and moisture can cause rust and damage.

Pillar 02 · Coverage Term

1 to 36 Month Warranty Protection

If something goes wrong after the first 30 days return window, don't worry. Your part is still covered by our warranty for up to 1 to 36 months.

Pillar 03 · Freight

Full Shipping Costs Coverage

We pay for shipping if your return is approved under warranty.

Pillar 04 · Fitment

Compatibility Coverage

We use your VIN# to match the right transmission. Even if it comes from a different year or model, it will fit and work like the original.

Pillar 05 · Recovery

Replacements & Refunds

If we approve your warranty claim, we will pick up the transmission and send you a tested replacement. If that transmission has the same issue, we will give you a full refund after we get it back.

Required · Pre-Installation

Follow the steps to keep your warranty valid.

Article IV · Scope of Coverage

What's covered, and what isn't.

A direct, side-by-side ledger of what falls inside the warranty boundary — and what stays outside it. No fine print.

Inside the boundary

What's Covered?

Our warranty covers essential internal components only:

  • Transmission case
  • Valve body
  • Torque converter
  • Planetary gears
  • Clutch packs
  • Key internal moving parts
Outside the boundary

What's Not Covered?

  • External accessories (sensors, cooler lines, mounts, brackets, oil pan etc.) are included for your convenience but not covered under warranty.
  • Warranty coverage is parts only. Labor is excluded unless previously approved in writing or purchased separately.
  • Any misuse or abuse — including activities such as racing or towing — as well as neglect, improper handling, or damage resulting from incorrect installation, unauthorized or unqualified repairs/modifications, are not covered.
  • Existing problems with the vehicle that will cause damage to the ordered part will also void the warranty.
  • The warranty excludes coverage for any delays, loss of time, transportation or towing expenses, or any related direct or indirect damages caused by a defect.
  • Leaks caused by old gaskets, filters, or seals are not covered.
