Description

Fraser Engines Remanufactured Transmission Quality Standards

Every Fraser Engines remanufactured transmission is built, tested, and validated to deliver dependable performance, long service life, and smooth operation under real-world driving conditions.

What’s Included & How We Ensure Quality

✔️ A remanufactured and improved torque converter is included with every transmission at no additional cost.

✔️ To prevent front seal leaks, vibration, and premature bushing wear, all torque converters are thoroughly tested for leak integrity, lock-up operation, concentricity, and balance.

✔️ Every fully remanufactured valve body receives complete system correction and recalibration, then is tested independently prior to installation.

✔️ All wear-prone valves are restored to stringent specifications and vacuum tested to verify proper sealing and operation.

✔️ Each remanufactured transmission undergoes hot, cold, load, and simulated road testing using our proprietary CARS® (Computer-Aided Road Simulation) dynamometer program, replicating real driving conditions before release.

Warranty You Can Trust

✔️ All Fraser Engines remanufactured transmissions are backed by an industry-leading, no-hassle nationwide warranty, providing real protection and peace of mind long after installation.

Important: The A604 (also known as 41TE or Ultradrive) is a 4-speed electronically controlled front-wheel-drive automatic transmission. Fitment varies by year, engine, solenoid pack, and TCM calibration. Always verify by VIN, transmission tag, and connector style before ordering.

Why Buy an A604 Transmission from Fraser Engines?

The A604 (41TE / Ultradrive) automatic transmission was Chrysler’s first electronic 4-speed FWD unit, and while it was innovative, many examples can develop wear, shift complaints, or internal valve body issues over time. A used or core transmission may have hidden wear, solenoid failures, or calibration issues that lead to poor performance and early failure.

Fraser Engines remanufactures every A604 transmission from the ground up, correcting known wear areas, updating internal components, and returning it to service with reliability and durability you can count on — not a short-lived rebuild or used take-out.

🔧 Full Ground-Up Remanufacturing

Every A604 transmission from Fraser Engines receives:

✔ Complete disassembly, cleaning, and inspection of every component
✔ Replacement of all clutches, steels, seals, bands, and friction materials
✔ Upgraded internal bushings, bearings, and thrust washers
✔ Corrected valve body & hydraulic control assembly
✔ Solenoid and sensor testing & replacement as needed
✔ Precision reassembly to factory torque and pressure specs

This comprehensive remanufacturing process restores proper clutch apply, line pressure, and shift quality — not just a quick fix.

🧪 Thorough Testing Before Shipment

Every reman A604 transmission is:

✔ Hot and cold tested
✔ Hydraulic pressure verified
✔ Solenoid function validated
✔ Load simulation checked

This ensures smooth, reliable shifting from first start to high mileage.

🚗 Built for Chrysler, Dodge & Plymouth Applications

The A604 was used across a wide range of front-wheel-drive Chrysler products, including:

  • Chrysler New Yorker, LeBaron, Town & Country

  • Dodge Caravan, Grand Caravan, Dynasty, Shadow

  • Plymouth Voyager, Grand Voyager, Acclaim

Fraser Engines verifies fitment by VIN and transmission tag to ensure you receive the correct A604 variant for your application.

🛡 Strong Warranty Protection

Fraser Engines backs every reman A604 transmission with industry-leading warranty coverage:

✔ Nationwide parts & labor protection (program dependent)
✔ Claims handled directly by Fraser Engines
✔ Optional extended coverage available
✔ Confidence and peace of mind long after installation

This is real warranty protection — not thin, parts-only coverage.
