Products & Quality
What is the difference between remanufactured, rebuilt, and used engines and transmissions?
The core difference is how thoroughly the unit is restored and tested.
Remanufactured: Restored as close to new as possible. Key components such as the block casting, crankshaft, and camshafts are inspected and remachined to OEM tolerances; any component that can't be restored is replaced, and all wear-prone internal parts are replaced with new components. Remanufactured engines include a new oil pump (high-flow where required) and a complimentary gasket set.
Rebuilt: Disassembled and repaired only at the points of failure. Many wear-prone parts are reused, and little to no comprehensive testing is performed.
Used: Salvaged from donor vehicles, typically left in original condition and, at most, cleaned and minimally tested. See our certified used options.
What is a Certified Pre-Owned (CPO) engine?
A CPO engine meets a defined set of quality standards and is verified on a SIM test stand that rotates the engine at normal operating RPM to check four things: compression (cylinder sealing), oil pressure and flow (lubrication and bearing wear), torque-to-turn (internal resistance and maintenance history), and VVT/VCT operation (variable valve/cam timing). Go Powertrain's CPO engines are typically 3-7 years old with varying mileage, and because maintenance history matters more than mileage, this testing reveals the engine's true quality. A CPO engine delivers high value without being re-machined like a remanufactured unit.
How does Go Powertrain quality-check remanufactured engines?
Every remanufactured engine goes through comprehensive machining, inspection, and testing to meet or exceed OEM specifications. Key steps include:
- 100% magnaflux crack detection on blocks and cast iron cylinder heads
- CNC machining of blocks (bored, decked, chamfered) with the specified cylinder cross-hatch honing
- 100% new pistons, rings, and bearings in every engine
- Air-gauging of cylinder bores, valve guides, lifter/cam bores, and crank journals
- Only new valves, seals, and lifters in every head; all plugs and fittings replaced
- Vacuum-decay and pressure-decay leak testing of heads, coolant, and oil passages
- Dynamic SIM testing for compression, oil flow, oil pressure, torque-to-turn, and unusual noise
How does Go Powertrain quality-check remanufactured transmissions?
Every transmission is fully disassembled, cleaned, inspected, and dyno-tested. Key steps include:
- All cases media-blasted; internal parts and bushings inspected and replaced as required
- 100% of friction components replaced with upgraded heavy-duty parts
- 100% of seals, O-rings, and gaskets replaced; solenoids tested and replaced if they fail duty-cycle tests
- Valve bodies disassembled, cleaned, measured, machined as needed, and tested before assembly
- 100% dynamometer tested for correct pressures and shift quality across the operating range
- Upshifts/downshifts checked against preset parameters; converter stall speed, lockup, and park mechanism verified
How are torque converters quality-checked?
- 100% dynamically balanced with furnace-brazed pumps
- 100% new bearings, O-rings, springs, rollers, and thrust washers
- New friction liners in overdrive lockup converters
- Endplay, hub/pump runout, and diameter checked
How are transfer cases quality-checked?
- 100% inspection of case halves for cracks, stripped threads, and internal wear
- Internal parts inspected, including chain stretch and main-shaft straightness
- Viscous clutch torque testing and spin testing for shiftability and noise
- Hydro-blast cleaning, 100% new seals, and air pressure leak-down testing
- New mounting studs where applicable

Cores & Core Charges
What is a core?
A core is your old, defective unit that you return when you buy a new or remanufactured product. Core returns matter for two reasons: they ensure proper disposal of used products, and they supply reusable materials - castings, casings, and certain internal parts are inspected, remachined, and reused where possible.
What is a core charge?
A core charge is a refundable fee based on the core value of the item you're buying. It's assessed if you don't return your core, return it late, or return it damaged. There's no standard rate - it depends on the item - and it's refunded once your core is returned, though a charge may still apply if the returned core is deemed unvaluable.
How do I return a core?
After your new unit is installed, call us and our core team will issue a bill of lading. Print two copies and hand both to the carrier at pickup, and your core ships back to be remanufactured. You can also use our online core return form. Note: if you return a core yourself without contacting Go Powertrain, you are responsible for all freight and will not be reimbursed.
How long do I have to return a core?
Cores must be returned within thirty (30) days. After that, you'll be charged the value of the unreturned core. Contact us to schedule pickup when your core is ready. This applies to most U.S. customers; outside the U.S., core returns are evaluated case-by-case, as return may not be cost-effective.
What condition must a core be in to get full credit?
For full core credit, the core must be returned in original packaging, fully assembled to the same build level as the replacement unit, and visually remanufacturable. Please note that the unit price does not include the core charge.
What is a valuable core?
A valuable core is free of physical damage such as cracks or holes - any crack or hole makes a core unvaluable, and you'll be assessed a full or partial core charge. If you're unsure about your core's status, send photos to your sales representative so you know what to expect up front.
What is a partial core?
Not every damaged core loses full credit. Because many internal powertrain components remain useful regardless of the casing or block appearance, you may pay only a portion of the core fee. The partial charge is a percentage of the full core value, based on factors like the location and severity of the damage.
Shipping & Returns
How long does shipping take?
Shipping typically takes 2-7 business days, depending on stock at the time of your order; out-of-stock units may take longer. Please contact us for an exact ETA before ordering.
Is shipping included in the price?
Roundtrip shipping is included in the product price in most cases for lower-48 commercial locations, provided: no liftgate or inside delivery is used (forklift or manual lift-off truck), the location is 53-foot semi-truck accessible, and someone is present for signature and at the time of core return. Residential addresses incur an extra $250 round-trip fee.
Are there additional shipping fees?
Additional fees may apply for: residential delivery ($250 round trip in the lower 48); redelivery if no one is available during the carrier's delivery window; and surcharges for parts of New York, Long Island, Cape Cod, and the Florida Keys. Changes to delivery location or special delivery services also incur extra fees, so please confirm your delivery address at the time of purchase.
Do you ship to Alaska, Hawaii, or internationally?
Yes. Alaska and Hawaii shipping is available at additional cost - contact us for an estimate. International shipping is also available with additional terms; call for pricing and warranty details.
What is Go Powertrain's return policy?
We accept returns and do not charge a restocking fee, but because these units are heavy, return freight is the customer's responsibility (up to about $600 in the lower 48) and is deducted from your refund. Refunds are processed within 12 days after the unit is returned and inspected. Please note: performance units are final sale and non-returnable, and any item that has been installed is not returnable. See our full shipping and returns terms.
Ordering & Availability
Why are obsolete or "no ETA" products listed on the website?
Some products are temporarily or permanently unavailable but remain listed for cataloging purposes. Supply chains change, so a product may become available again - always verify current availability and timeframes with a sales rep. Other part numbers may also fit your vehicle, so call to verify fitment and pricing.
How do distributors and resellers register a part they've sold?
Distributors and resellers can register a part sold on our part registration page.
