The Transmission Warranty.
Protected · VIN-Matched · Pro-Inspected · 1–36 Month Coverage
We stand by our used transmissions. Each one comes with a simple, clear warranty to give you peace of mind from the moment you order — and you see HD photos of your exact unit before it ever ships.
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. The warranty term stated on your invoice controls. Coverage begins on the date of purchase and is parts-only: replacement of the covered unit, with labor, towing, rental, storage, and fluid costs excluded unless a labor protection plan was purchased in writing.
Optional Add-On · Labor Coverage
Cover the labor, not just the part.
Your warranty replaces the unit. It does not pay your shop. Labor coverage is a separate, optional plan you buy once, before the transmission ships — and you choose the amount, so it matches the job your shop has actually quoted rather than some figure we picked for you. If a covered failure is confirmed, that amount is paid toward your installation labor.
| Labor covered on an approved claim | Your one-time cost |
|---|---|
| $250 | $50 |
| $500 | $100 |
| $1,000 | $200 |
| $1,500 | $300 |
| $2,000 | $400 |
| $2,500 | $500 |
Choose your tier before dispatch. Labor coverage cannot be added once the unit has shipped, and never after a fault has appeared. The figure you pick is a fixed cap paid once against a documented labor invoice — it is not an hourly rate and it is not open-ended.
What it covers
Labor coverage follows the same boundary as the warranty itself: the internal failure of the unit we supplied.
- Internally lubricated and internally driven components inside the unit
- No gasket or seal is included — labor coverage follows the internal failure only
- External components — coolers, lines, sensors, solenoid packs mounted outside the case, mounts and linkage — stay outside it, exactly as they do under the parts warranty
What you have to prove
We pay labor on evidence, not on opinion. A claim on this plan needs the fault isolated to the unit itself, beyond argument:
- A diagnostic from a certified shop naming the failure and ruling out the converter, the cooler circuit, the linkage and the vehicle's own electronics
- Hard readings that support it — line pressure, stall test figures, fluid condition, scan data and stored codes
- Photographs or video of the fault — slipping, no-engagement, harsh shift or noise — where it can be seen or heard
- Your installation invoice showing our pre-installation checklist was followed
Diagnostic time — how it works
Finding the fault is your shop's time and you pay for it when it happens. If your shop needs two or three hours to diagnose, that is your cost on the day, whatever the outcome.
If the diagnosis confirms our unit failed and the claim is approved, that diagnostic time is credited back to you out of the labor amount you are covered for. If the unit turns out to be sound, the diagnostic stays with you. That is the trade that makes labor coverage possible at all: we pay when the part is at fault, and we are not funding open-ended investigation of everything else on the vehicle.
Where labor coverage is not offered
Three categories cannot be written for labor at any tier:
- CVT transmissions
- Ford 5.4L engines
- Any unit more than 15 years old
This is an underwriting limit, not a comment on the part. These units are still sold and still carry the standard parts warranty in full — labor simply cannot be added to them.
In short: the parts warranty is included with every unit and always has been. Labor coverage is the optional layer on top, priced at one fifth of the amount it protects, chosen by you at the size of your own job, and paid out when the evidence shows our unit was the cause.

Palletizing & Freight Dispatch
Strapped, wrapped, and shipped — typically 3–5 business days in transit.
§ Guarantee
Refund Before Shipment
100% Refund If You Reject the Photos
If you review the pre-shipment photos and reject the part before freight dispatch, you receive a 100% full refund — zero cancellation or restocking fees.
Your written photo approval is what releases your order for shipping. Nothing ships without it.
§ In Transit
Cancellation After Approval
Cancellations After Approval or In Transit
Once you've given written photo approval and the carrier has dispatched your shipment, actual outbound and return freight costs (approximately $350–$400 each way) are non-refundable and will be deducted from any refund.
Article III · Return Terms & Conditions
The fine print, without the fine print.
Four 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. You also get a full refund at any point before dispatch if you reject the pre-shipment photos (see Article II).
After 24 hours, we begin preparing your transmission for shipment. If you cancel after this time for any other reason, the following charges will apply:
- 20% restocking fee
- Round-trip freight cost (approximately $350–$400 each way), if your part is already shipped
§ B · 30-Day Window
Clause B
30-Day Return Window
Let us know about any visible damage, fitment discrepancy, or issue in writing within 30 days from the date of purchase, with the unit still uninstalled and in its original delivered condition. We can't take returns after 30 days from the date of purchase.
All returns require a written Return Authorization (RMA) from us before the part ships back. Returns sent without an RMA cannot be accepted at our dock.
Please note: If you send the transmission back even though it was delivered in good shape (changed mind, ordered wrong part, no issue found), it counts as a canceled order. In that case the 20% restocking fee applies and round-trip freight remains your responsibility.
Check out our Return Policy here.
§ C · Delivery Day
Clause C
Delivery Inspection & Freight Receipt (BOL)
Inspect the crate and unit before signing the carrier's Bill of Lading (BOL). The driver must wait while you or your mechanic check for case cracks, broken ears, or bent components.
- If any damage is found, write "RECEIVED DAMAGED — [describe damage]" on the BOL before signing.
- Send us photos of the damage and the noted BOL within 48 hours of delivery.
- Damage discovered after the driver leaves (concealed transit damage) must be reported within 48 hours of delivery with photos of the unit and the packaging.
Freight carriers reject physical-damage claims on a clean signed BOL. If you sign without noting damage and don't report concealed damage within 48 hours, transit-damage claims cannot be honored. A case cracked or physically damaged after delivery is not covered under warranty.
§ D · Fluid Rules
Clause D
Fluid & Installation Discipline — Strict Void Condition
Transmission failure after installation is most often caused by fluid problems, not the unit itself. To preserve coverage, your certified installer MUST:
- Completely flush the transmission fluid lines and cooler system before installation.
- Install a new transmission filter and pan gasket (where applicable).
- Fill with brand-new, manufacturer-specified fluid to the correct level.
- Check and clear all ECU/TCU fault codes prior to test driving.
- Keep receipts for fluid, filter, and gasket — they are required for any claim.
STRICT VOID: Damage caused by improper fluid level, low fluid, contaminated fluid, or incorrect fluid specification voids this warranty. Internal torque converter failure caused by improper installation torque or seating is likewise excluded. These conditions are verifiable on teardown, and no claim, return, or refund can be honored where they are found.
§ E · Returning a Faulty Unit
Clause E
Returning a Faulty Unit — 30 Days
If a unit develops a fault and the outcome is a return, it must come back to us within 30 days of the fault occurring. A used transmission that sits for months after a fault cannot be assessed, cannot be reconditioned, and cannot be put back into service by anyone. That is why this is a firm condition rather than a preference.
You will never be on this clock for time that belongs to us. You cannot return a unit until we have authorised it and sent you the Bill of Lading, so any period before we do that — and any delay of ours after it — does not count against you. We arrange the collection, we cover the freight, and we tell you in writing where the 30 days stands.
VOID CONDITION (V·05): Where a return has been authorised and we have provided the Bill of Lading, and the unit is not made available for collection within the 30-day period, warranty protection on that unit is forfeited. Time spent waiting on us is excluded from the count.
COLLECTION: When a return is authorised we send you the Bill of Lading. Print two copies and keep them with the unit. The driver takes a printed copy by hand and cannot accept it on a phone screen, and they will not wait. If a driver arrives and there is no printed copy to hand over, that is a failed collection — it costs between $200 and $300, and it falls to you where the instruction was given and not followed. We remind you about this every 12 hours until you confirm the copies are printed, precisely so that it never happens.
DRY RUN FEE: On pickup day the carrier needs three things ready — the unit secured on a pallet and strapped exactly the way it was delivered to you, the printed Bill of Lading copies for the driver, and someone present during the pickup window. Where we have emailed the BOL at least one business day ahead and the driver arrives to find the shipment not ready or the paperwork missing, the carrier bills a dry run fee for the wasted trip, and that fee is the customer’s responsibility. It is fully avoidable: if your timing changes, one email before pickup day moves the collection at no cost.
While the claim is open, keeping the unit dry, covered and off the ground with fluid and ports sealed protects it — and protects your claim. If the unit needs moving or handling differently, tell us and we will arrange it at our cost. Anything at all you are unsure about, call Bella, Complaints Specialist, on 307-441-9797, Monday to Friday, 8:30 to 6:30 Eastern.

Article IV · 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
