Who makes the Ram 8 speed transmission?

Ram is one of the only automakers to still use an 8 speed automatic transmission in their trucks. Most modern trucks now have 10 speed automatic transmissions. But Ram is sticking to their guns and continuing to use the same tried-and-true 8 speed automatic that’s been around since 2013.

What Transmission Do I Have?

Known as the TorqueFlight 8, the Ram 8 speed transmission is actually built under license from the German transmission specialists ZF. There were several engines available, and the one you got depended on which engine you had. For example, the Ram 1500 V-6 got the 850RE transmission, which was of course designed by ZF and built under license in the United States. The Ram 1500 5.7 Hemi initially received the ZF8HP70 transmission. But that was eventually bumped up to the more robust 8HP75. When used in conjunction with the eTorque mild hybrid system, the transmission gains a hydraulic pressure accumulator which allows for more seamless acceleration when the start/stop system is activated.

Some of the symptoms of a bad 8HP70 valve body include:

  • Unusually harsh shifts
  • Delayed gear engagement
  • Torque converter not engaging
  • Noise on downshift
  • Flared shifts
  • Loss of gears

If you want to keep your vehicle on the road as long as possible, then you’ll want to consider investing in a remanufactured 8HP valve body from a company like Street Smart Transmission. These are built in a factory by trained technicians, and the valve body has to pass multiple quality inspections throughout the build process. Once complete, the remanufactured valve body is then dyno tested on a special progRam called CARS (Computer Aided Real-world Simulation). This puts the valve body through a number of real-world driving scenarios, so technicians can see if it operates properly, and make any necessary adjustments before its shipped to the customer. And it gets a 3-year/unlimited mile nationwide warranty, which can even be transferred to a new owner if you sell the vehicle.
