Built for longevity and smooth operation, this Aisin transmission is renowned for strong and reliable shift performance that supports the medium-duty truck duty cycle of constant stop-and-go delivery, towing, and vocational service. Part of maintaining the AS68RC to keep it efficient includes routine fluid exchanges and a regular leak check. In commercial applications, this AS68RC Transmission for Sale at our site is one of the most durable medium-duty automatics available and remains a popular choice with vehicles from RAM 4500/5500 chassis cabs to Isuzu and Mitsubishi Fuso commercial trucks. A bit of regular maintenance goes a long way, and with proper care the AS68RC delivers reliable operation when you need it most.

Key Features of the AS68RC Transmission

6-Speed Configuration: Six forward gears greatly improve fuel economy and acceleration by offering a broader spectrum of gear ratios compared to older 4-speed and 5-speed medium-duty automatics.

Longevity: Designed for medium-duty commercial truck duty cycles and rated for 750-900 lb-ft of input torque.

Silky Smooth Shifting: Aisin’s renowned precision construction delivers smooth shift transitions for drive comfort and passenger comfort.

Hydraulic and Electronic Control: Electronic control unit (ECU/TCM) manages shifting patterns and torque converter lockup based on driving conditions, throttle position, load, and grade.

Lockup Torque Converter: Locks up at cruising speeds to eliminate slip, improving fuel economy and keeping transmission fluid temperatures under control.

Advanced Electronics: Modern electronic management permits adaptive shift quality and adjustment to driving conditions.

Adaptive Learning: Adjusts shift points and quality to driving conditions and driver behavior over time for optimal performance.

Wide Gear Ratios: Flexible, efficient performance from heavy launch under load to highway overdrive cruising.

High Torque Capacity: Rated for high-torque medium-duty diesel applications including the 6.7L Cummins (RAM 4500/5500) and the larger Isuzu 6HK1-TC 7.8L diesel.

FAQs

Availability of AS68RC Transmission for Sale?

Yes, you will find the best quality Aisin AS68RC transmission for sale at a very reasonable price with donor truck and engine pairing confirmed. Multiple applications available including RAM 4500/5500 Cummins, Isuzu commercial trucks, Hino medium-duty, Mitsubishi Fuso Canter, and Freightliner M2.

What is the price of the AS68RC Transmission for Sale?

$6,799.99 for this listing (SKU 134). Reman AS68RC runs $7,500 to $10,500+ depending on source; new OEM units run $9,500 to $14,000+.

What maintenance does the AS68RC transmission require?

Regular maintenance includes fluid changes using Aisin-specified ATF (typically Type T-IV or equivalent) at the manufacturer’s intervals (typically every 30,000-50,000 miles for severe-duty commercial use), inspections for leaks at the input shaft seal and output shaft seal, monitoring shifting performance for any signs of slippage or delayed engagement, and following the manufacturer’s service intervals as published in the donor truck service manual.

Is the AS68RC transmission reliable?

Yes, the AS68RC transmission is known for its reliability in medium-duty applications, provided it is properly maintained and used within its design parameters (750-900 lb-ft torque rating). The Aisin Seiki precision construction and proven Toyota Group engineering have made the AS68RC one of the most respected medium-duty automatic transmissions in the commercial truck market.

Does the AS68RC transmission have electronic controls?

Yes, the AS68RC is electronically controlled, utilizing an electronic control unit (TCM) to manage shifting patterns, torque converter lockup, and adaptive shift learning based on driving conditions, load, and driver behavior.

What are the driving characteristics of vehicles equipped with the AS68RC transmission?

Vehicles equipped with the AS68RC typically offer smooth and efficient shifting, capable of handling heavy commercial loads with good acceleration and fuel efficiency typical of medium-duty trucks. The 6-speed gear count combined with the lockup torque converter provides the right balance of low-end launch capability and highway cruising efficiency for the medium-duty Class 4-5 truck duty cycle.

How can I prolong the lifespan of the AS68RC transmission?

Regular maintenance, including fluid changes at recommended intervals (Aisin-specified ATF only), inspections for leaks, monitoring transmission fluid temperature in heavy-duty applications (consider an auxiliary cooler for severe service), and addressing any issues promptly can help prolong the lifespan of the AS68RC. Avoiding excessive towing or hauling beyond its 900 lb-ft rated capacity also contributes to longevity.

Will the AS68RC from a RAM Cummins work in an Isuzu truck?

The physical case is the same, but the TCM calibration differs significantly between the RAM 4500/5500 Cummins application and Isuzu medium-duty applications. For optimal performance, the donor truck and engine pairing should match the receiver application. Reprogramming may be required when changing applications.
