Find Your Parts Quicker , Easier and More Reliable
Trinity Auto Parts supplies tested used OEM transmissions and remanufactured transmissions, automatic and manual, for cars, trucks and SUVs across the USA and Canada. Give us your VIN and the code from the transmission tag, and we confirm the fit before the unit ships, with a warranty and free shipping.
Every unit, including CVTs and heavy-duty truck automatics, comes from a well-maintained running vehicle and is fully tested, inspected and guaranteed before it ships. Every quote states the mileage, what is included and the warranty term, so you know exactly what you are buying before you pay.
Every transmission is inspected before it ships: shifting, leaks, fluid condition and case damage are all checked. Remanufactured units are rebuilt with new wear components and tested. You will not receive a unit that has simply been pulled and boxed.
One model can use several different transmissions in the same year depending on engine, drivetrain and towing package, and the differences are not always visible from outside. We match the transmission to your 17-digit VIN and the code on the tag, and confirm fitment before dispatch.
Every transmission ships with a warranty, up to 2 years on select parts, with the exact term written on your quote. Shipping is free across the USA and Canada, return shipping is free, and delivery is typically 3–5 business days in the continental US.
We have been supplying used and remanufactured drivetrain parts since 1990 and are BBB accredited. You talk to people who understand transmission codes and can tell you what a listing actually includes.
A tested, low-mileage used OEM transmission is the lower-cost route for most vehicles. A remanufactured transmission costs more but has new clutches, seals and wear parts inside. We will tell you honestly which option makes sense for your vehicle, mileage and budget.
Use the quote form on this page or call +1 725-208-4566. Tell us the VIN, the transmission code if you have it and what the old unit is doing, and we will come back with options, a price and a delivery estimate.
This guide is for anyone replacing an automatic, manual or CVT transmission in a car, truck or SUV. Decide first between a tested used OEM unit and a remanufactured one; then identify the exact transmission code so the replacement matches your vehicle.
A transmission is the gearbox between the engine and the driveshaft or axles. It multiplies engine torque and selects gear ratios so the engine stays in its working range. Automatics shift with a torque converter, planetary gearsets and a valve body; manuals use a clutch and gear pairs; CVTs run a belt or chain on variable pulleys.
For most vehicles a tested, low-mileage used OEM transmission is the best value: it is the factory unit, already proven in a running vehicle, at a fraction of the cost of new. Choose remanufactured if the vehicle tows, has very high mileage, or you want new clutches and seals inside.
| Factor | Used OEM | Remanufactured |
|---|---|---|
| Condition | Original unit from a donor vehicle, tested, mileage disclosed | Disassembled, cleaned, wear parts replaced, tested to specification |
| Typical cost vs new | Often 50–70% less than a new dealer unit | Less than new, more than used |
| Availability | Widest; depends on donor supply for your exact code | Good for common codes; longer lead time on rare ones |
| Best for | Daily drivers, older vehicles, budget repairs | Towing, high-mileage originals, long-term keepers |
| Component | Usually included? | Notes |
|---|---|---|
| Complete case with gear sets, clutches, valve body and pump | Yes | The core of every assembly |
| Torque converter (automatics) | Varies by listing — confirmed before shipping | Ask if you need it supplied; some listings ship without |
| Bell housing | Usually | Integral on most automatics; separate on some manuals |
| Internal harness, solenoids and speed sensors | Usually | As fitted in the donor vehicle |
| External sensors, shift linkage, mounts, cooler lines, dipstick tube | Varies by listing — confirmed before shipping | Plan to transfer yours |
| Fluid, filter, pan gasket, flexplate or clutch | No | Shops fit new fluid and filter at install |

A used transmission is sold as it came out of the donor vehicle, tested but not opened. A rebuilt transmission has had the failed parts replaced and the rest inspected and reused. A remanufactured transmission is fully disassembled, cleaned and rebuilt with new wear parts to specification. A complete tested used or remanufactured unit is usually the faster route back on the road.
The code on the transmission tag identifies the family, and it matters more than the vehicle name. In a GM code such as 4L60E, the first digit is the number of forward speeds, L means longitudinal (rear-drive) layout, the number is the relative torque rating, and E means electronic control. Ford codes such as 6R80 follow the same idea: six speeds, rear-drive, torque class 80. ZF codes such as 8HP70 mean an eight-speed hydraulic planetary unit in the 70 torque class. Units sharing a family code can still differ by year, so we always match to the VIN as well.
The torque converter is the fluid coupling between the engine and an automatic transmission; it lets the engine idle while stopped and multiplies torque as you pull away. Whether one is included varies by listing and is confirmed before shipping. Many shops prefer a new or remanufactured converter whenever a transmission is replaced, because debris from a failed unit collects inside the old converter. Ask us if you need one supplied.
A shop will typically transfer external sensors, linkage and mounts, replace fluid and filter, and flush the transmission cooler and lines so debris from the old unit cannot contaminate the new one. Some modern transmissions carry the control module inside the unit or on the valve body; on those vehicles the module may need programming or a relearn to your VIN, and adaptive shift values are usually reset with a scan tool. Ask us whether the unit you are buying can be supplied ready for your vehicle.

Yes. Every automatic and manual transmission is inspected before it ships, with checks for proper shifting, leaks, fluid condition and case damage. Remanufactured units are rebuilt with new wear parts and tested to specification. We also confirm the transmission code and VIN match before the unit ships.
It varies by listing, so we confirm it with you before shipping. Some used automatic transmissions come with the torque converter and some ship without it. Many shops prefer a new or remanufactured converter anyway, since debris from a failed transmission collects inside the old one. Ask us if you need one supplied.
For most drivers a complete tested used or remanufactured transmission is faster and more predictable than a rebuild. A rebuild takes the vehicle off the road while the unit is opened up, and the final cost depends on what is found inside. A used or remanufactured unit arrives with a warranty and a known mileage.
Look for the ID tag or stamped code on the transmission case; on many vehicles the option-code sticker in the glove box or door jamb also lists it. If you cannot find it, send us the 17-digit VIN and we will identify the transmission your vehicle was built with. We match to the VIN either way.
Yes. We source tested used and remanufactured CVT transmissions alongside conventional automatics and manuals. CVTs are matched to the VIN just like any other unit, and the quote states the mileage and warranty term. Because many CVTs require a specific fluid and a relearn after installation, tell your shop it is a CVT before the job.
Yes. Every transmission we sell ships with a warranty, and select parts carry a warranty of up to 2 years. The exact term for your unit is written on the quote so there is no guesswork. If you have questions about coverage, call +1 725-208-4566 or email [email protected] before you order.
Yes. We ship transmissions across the USA and Canada, and shipping is free. Typical delivery is 3 to 5 business days in the continental US; deliveries to Canada and freight items can take a little longer. Your quote includes an estimated delivery time for your address.
The 17-digit VIN is the most important item, because it tells us which transmission your vehicle was built with. Add the year, make, model, engine size, drivetrain (2WD, 4WD or AWD) and the transmission code from the tag if you can see it. Photos of the old unit help us confirm the match before dispatch.
Return shipping is free, so you are not stuck with the wrong unit. We match every transmission to your VIN and the code on the tag and confirm fitment before dispatch, which keeps fitment problems rare. If something is still wrong, contact us at +1 725-208-4566 and we will arrange the return and the correct part.
