Spoon Parts USA stocks 5 verified listings in the 545RFE category, priced from $101 to $3,999. Every part is sourced from U.S. sellers, inspected before it ships from our Ohio warehouse, and backed by fast domestic delivery. Whether you're rebuilding a daily driver, restoring a project truck, or keeping a fleet on the road, this guide walks you through what 545RFE parts do, how to pick the right one, and what to check before you install.
The 545RFE plays a specific role in your vehicle's driveline, chassis, or accessory system. Understanding that role is the first step in ordering the right unit the first time. Every listing on this page identifies the exact fitment year range, submodel, and drivetrain configuration so you can match a replacement to your VIN without guessing. If you're new to sourcing used or remanufactured 545RFE parts, start by comparing the option pricing on this page — the current range is $101 to $3,999, with most buyers landing near $1,014.
Because Spoon Parts USA aggregates listings from multiple verified sellers, you'll see condition tiers side by side: OEM used, remanufactured, and new-old-stock. Each carries a different price and warranty profile. Buyers who prioritize cost typically choose OEM used; buyers who prioritize longevity typically choose remanufactured. Both categories are covered here, and both ship the same day when ordered before 2 PM Eastern. For related driveline hardware, browse our 4L80 Transmission and 4R100 categories.
Wear symptoms vary by part, but the pattern is consistent: unusual noise, fluid loss, vibration under load, or a warning light that returns after a reset. A 545RFE that's approaching end of life will often exhibit intermittent symptoms first — a whine under acceleration, a chatter during shifts, or a stiff pedal that softens once warm. Ignoring these signs almost always compounds the repair cost, because a failing 545RFE puts extra load on adjacent components. If you catch the symptoms early, replacing the unit alone usually restores full function.
We recommend that any driver who suspects 545RFE wear pull a scan report and take a short test drive with a mechanic before ordering. The scan will confirm whether the symptom traces back to the 545RFE or to a related sensor, harness, or actuator. If the fault code isolates to this part, you can order confidently from the 5 listings above. Buyers frequently pair a 545RFE replacement with our 10R80 to address both wear items in a single service visit.
Fitment is the single most important variable. A 545RFE that looks identical between two model years can have different mounting bosses, sensor connectors, or gear ratios internally. That's why every listing on this page includes the seller's stated fitment data and mileage where available. Match year, make, model, submodel, drivetrain (2WD / 4WD / AWD), and transmission code before adding to cart. When in doubt, message the seller through Spoon Parts USA — most listings respond within a few hours during business days.
After fitment, the second variable is condition. A low-mileage OEM used 545RFE from a wrecked donor vehicle is often the best value: original engineering, verified operation, and a fraction of the new-part price. Remanufactured units cost more but ship with new wear components and a longer warranty. New-old-stock (NOS) is rare in this category but occasionally surfaces — expect to pay a premium of 40–80% over used pricing when it does. Compare current listings side by side; our sort tools let you rank by price, mileage, or seller rating.
The third variable is total landed cost. A cheaper 545RFE that ships from the West Coast may cost more once freight is added compared to a slightly higher-priced unit shipping from our Ohio warehouse. Every listing on this page ships from Ohio, so freight is predictable and fast — typically 2–5 business days to any address in the lower 48. Orders over $99 ship free. If your build also needs a 5.0 Coyote Engine, bundling both saves on packaging and gets you a single tracking number.
Cross-referencing part numbers is the fastest way to confirm compatibility. Pull the casting number, tag, or metal ID plate on your existing 545RFE and compare it against the listing photos above. If the numbers match, fitment is confirmed. If they don't match but the vehicle year, make, and model line up, contact the seller — many 545RFE units are interchangeable across a range of casting numbers because internal calibration is identical.
For buyers running modified vehicles, be aware that a 545RFE designed for a stock drivetrain may not hold up under increased power, larger tires, or heavier towing. Ask the seller whether the unit has been upgraded internally, or plan to source upgrade components separately. Our 42RLE Transmission catalog often has the supporting parts you'll need for a performance build.
A 545RFE replacement can be a straightforward bolt-in job or a full-day project depending on your platform. Before you start, review the factory service manual for torque specs and fluid capacities. Have the right tools staged: a floor jack rated for your vehicle's weight, safety stands, penetrating oil for any fasteners exposed to road salt, and fresh gasket or seal material if the unit ships without one. Skipping the seals is the single most common cause of a same-day leak after installation.
Torque every fastener to spec. Over-torqued bolts warp housings and cause slow leaks; under-torqued bolts back out under vibration. Use a calibrated torque wrench and follow the pattern in the service manual. If the 545RFE uses a fill plug and vent, verify the vent is clear before your first drive — a blocked vent will build internal pressure and push fluid past new seals within a few miles.
After installation, drive gently for the first 50 miles. Check for leaks, listen for noise, and re-torque any accessible fasteners after a heat cycle. Most sellers on Spoon Parts USA offer a limited return window if the part fails within the stated period, but that window starts on delivery — inspect and test-fit as soon as the box arrives.
Beyond the 545RFE itself, plan to replace any single-use fasteners, gaskets, or seals identified in the service manual. Order fluids in advance so you're not idling the job at a parts counter — most 545RFE installations call for a specific viscosity and additive package that's worth sourcing correctly. If your job also requires accessing adjacent driveline components, our 4R70W category has the supporting hardware.
Every listing on Spoon Parts USA carries the seller's stated warranty. Most OEM used 545RFE units include a 30-day parts warranty; remanufactured units typically extend to 90 days or one year. Full warranty terms appear on the listing page and in your order confirmation. If a part arrives damaged or DOA, contact us within 48 hours — we'll coordinate the return, replacement, or refund with the seller and cover return freight when the fault is on our end.
Buyer protection also covers fitment errors. If you order the correct part number as listed and it doesn't match your vehicle, we accept the return. If you order the wrong number and it fits differently, restocking terms apply. This is why fitment verification before ordering matters — a five-minute check of your casting number saves the two-week round trip of a return.
Every 545RFE listing on this page ships from our Ohio warehouse. Domestic delivery times average 2–5 business days depending on your zip code, with real-time tracking sent to your email at label creation. Orders placed before 2 PM Eastern typically ship the same business day; orders placed after 2 PM ship the next business day. Free shipping applies to any order over $99. Heavy freight items over the standard weight limit ship via LTL carrier and require a delivery appointment — the listing will note freight requirements before checkout.
For time-critical repairs, expedited shipping is available at checkout. Contact us before ordering if you need next-day service and we'll confirm cutoff times based on your zip code. We do not currently ship to Alaska, Hawaii, or international addresses for oversized freight, but we can quote air freight on smaller 545RFE units on request.
Start with year, make, model, submodel, drivetrain, and transmission code. If your 545RFE carries a casting or ID number, cross-reference it against the listing photos. When in doubt, message the seller — they respond within a few hours during business days and can confirm fitment before you order.
Used means the 545RFE was pulled from a donor vehicle, tested, and cleaned but not internally rebuilt. Remanufactured means the unit was disassembled, worn parts were replaced with new components, and it was reassembled to factory tolerance. NOS (new-old-stock) means a genuinely new, never-installed part that has been sitting in inventory. Pricing scales with condition tier.
Warranty length depends on the seller and condition. OEM used units typically carry 30 days; remanufactured units 90 days to one year. Full terms are on the listing page. Warranty starts on delivery date, not order date.
Yes, within the seller's stated return window. Contact us within 48 hours of delivery if the part arrives damaged or DOA. Fitment returns are also accepted when the buyer ordered the correct part number as listed. Restocking terms apply for buyer-error returns.
We don't perform installations, but many listings include installation notes from the seller. Our support team can also connect you with independent shops in the Ohio region if you'd like the work done locally after delivery.
