JASPER® remanufactured Dodge/RAM 68RFE transmissions are built to meet, or exceed, OEM measured standards and have a 3 year/100,000 mile nationwide, transferable parts and labor warranty. Click here for complete warranty information. This automatic transmission is completely remanufactured, assembled to exacting tolerances, and live-run dynamometer tested for reliability.
The 68RFE transmission family is widely used in popular applications such as the Chrysler 200, Pacifica, Sebring, Town & Country; Dodge Avenger, Grand Caravan, Journey; Ram C/V, Promaster; and Volkswagen Routan.
The 68RFE transmission family is prone to issues that include: loss of 3rd or 6th gear, pump cross leaks, cooler system contamination/failure, high bearing failure rate, cracked/leaking front cover bolt holes, burning of torque converter lining and TCC slip codes, solenoid failure/line pressure codes,
cracked lock-up piston, lock-up failure, and vibration/noise.
Each converter is dynamically balanced. The external converter shell is balanced independently of the converter stator and turbine to ensure the converter is accurately balanced.
JASPER® installs additional friction discs in the Underdrive clutch (12 discs total compared to 10). This provides a 20% increase in torque capacity.100% installation of the Sonnax Smart Tech® drum on all 68RFE transmissions. This drum utilizes double-sided friction plates with a higher heat capacity, preventing heat-related clutch plate warping.JASPER’s 68RFE Transmissions with the Sonnax Smart Tech® drum include a larger piston surface area, resulting in an 18% increase in overdrive clutch torque capacity, compared to OE applications.
100% installation of NEW pump bushing.JASPER’s updated pump gear has a tighter fit with the converter hub at the drive lugs to reduce engagement play and noise.100% installation of NEW front pump cover to prevent leaking.
100% replacement of converter lining.
JASPER blocks the pump channel in early pumps to replicate the late pump design, preventing converter drain.
JASPER installs an anodized aluminum TCC limit valve and hardened sleeve on early models to prevent hydraulic leaks and future wear.
100% replacement of TCC accumulator spring with an improved design to prevent spring failure.
JASPER applies a thread lock on accumulator cover bolts to prevent the cover from becoming unsecured from the valve body.
100% installation of NEW OE pressure transducer and speed sensors (2).
JASPER 100% replaces dampener springs with new springs on stock converters.
All units are fluid tested.Each solenoid pack and range sensor is tested to ensure proper function.All cooler filter bypass valves are tested for proper function.Every unit is dynamometer tested.
100% installation of a Sonnax Triple Disc Converter.The Sonnax Triple Disc Converter kit includes an additional friction disc providing a 50% increase in lockup torque capacity.The kit also comes with a durable damper assembly, designed to work with the triple disc system, providing a smooth lockup application.The Triple Disc Converter kit has a billet front cover with thicker walls, stronger mounting pads, and an integrated pilot resulting in a front cover that will not crack.
