Max tow capacity for a First Generation 5.9l Cummins is 11,900 lbs.

Varies from 250,000 miles to million miles.

avg price around here is 3500-5500. thats for a decent first gen that needs some work, like exterior or interior.

First Generation, 1981 – 1993 The first generation was launched in 1981 and named for the Ram hood ornament that has been used on Dodge vehicles since 1933.

To me the Holy Grail is an early-1998 Cummins 4×4 12-valve. The rear Quad Cab doors only started opening in 1998, but halfway through the model hear they started with the computerized 24-valve biz. That’s the best body configuration of the most reliable truck ever built and it’s got power potential as good as any.

Our 6 speed Allison Conversion Kit and Allison Transmission Package are a great alternative and upgrade for your transmission. Dodge offered three basic transmission designs behind the Cummins equipped light duty 2500/3500 pickup trucks from 2003 to 2018.

All you have to do is open up the hood:

1. If your yellow dipstick handle is on the right side of your engine (the driver’s side), you’re likely looking at a vehicle with an Aisin transmission.
2. If your dipstick is just to the left of your engine, you’re most likely dealing with the 68RFE.

The Aisin is a much smoother transmission, unloaded or loaded. It also runs cooler when towing heavy. It doesn’t have the quirkyness on downshifts that the 68 does. It can handle a lot more input torque(which means better for adding power in the future).

Anywhere between 1 mile and 1 million miles is a safe bet. There are so many factors….it’s just not possible to name an expected service life.

Toyota Motor Corporation’s A family is a family of automatic FWD/RWD/4WD/AWD transmissions built by Aisin-Warner. They share much in common with Volvo’s AW7* and Aisin-Warner’s 03-71* transmissions, which are found in Suzukis, Mitsubishis, and other Asian vehicles.

Lexus and Toyota — which rely on older transmissions in many of their models — were the best-performing brands in the survey. Lexus or Toyota has topped the survey since 2011. Audi, Mazda and Subaru rounded out the top five.
