Remanufactured ZF8HP70 Valve Body vs. Rebuilt or Used

Reman vs Rebuilt ZF8HP45 Valve Body?
Both are good options but the best option for you depends on the transmission problem, the year, make and model of vehicle, the mileage and the vehicle value.
Reman vs. Used ZF8HP Valve Body?
Buying a used ZF8HP45 is risky since you do not know what you are going to get. This could cause various electronics to fail and require replacement.

ZF8HP45 History

Chrysler Group LLC initially received the 8HP 8-speed automatic transmissions from the ZF plant in Saarbrücken, Germany. By 2013, in parallel with Chrysler Group, ZF had set up a new transmission production plant in Gray Court, South Carolina. ZF Friedrichshafen and Chrysler Group have reached a supply and license agreement for the 8HP. Chrysler Group is licensed to produce the 8HP at the company’s Kokomo Transmission Plant and the Kokomo Casting plant, production began in 2013. This transmission is marketed by Chrysler under their own brand name, the Torqueflite 8.

2nd generation 8HP products were released starting in 2014. Efficiency improvements over the original design include a wider ratio spread of 7.8:1, reduced drag torque from the shift elements, reduction in required oil pump pressure, and broadened use of the coasting and start-stop systems. ZF estimated fuel economy improvement over 1st generation 8HP kits to be 3%. Refinements were also made with respect to vibration.

3rd generation 8HP products were released starting in 2018. Major improvements are total spread of 8.6 and a fuel economy improvement of 2.5% compared to the 2nd generation. There are several options in maximum torque available, also the gearbox is available with mild hybrid and plug in hybrid options: With 15 kW and 200 NM supporting boosting and recuperation in combination with 48 Volt technology up to 90 kW and 250 NM for usage with higher voltage.

If you want to solve all of your valve body related issues, and have the security of a 3 Year/No Hassle Warranty, then you need to consider a remanufactured ZF8HP45 / ZF8HP70 / ZF8HP90 valve body from Street Smart Transmission. Each one is built in a state of the art factory, by Certified valve body technicians. And our strict quality control process ensures that each valve body that we ship, will exceed the manufacturer’s specifications using a road simulation tester.

How It’s Done
•Using specialized equipment, each valve body is inspected for warping, cracks, and tensile strength prior to the build
•Every valve, piston, spring and bore is tested to ensure that it conforms to OE specifications
•Wear components like valve body gaskets are replaced
•7 solenoids get bench tested prior to it leaving
•Pressure switch and speed sensors are tested
•The remanufactured TCM is pre-programmed to each customers specific VIN number code, ensuring proper functionality right out of the box.

Once finished, every remanufactured ZF8HP valve body is thoroughly bench tested using a Superflow AXILINE Valve Body Tester. This state of the art machine is able to simulate actual road conditions, which allows the shift points and functionality to be fine-tuned prior to shipment.

So if you’re looking for a remanufactured ZF8HP valve body that is engineered to exceed both OE specifications and customer expectations, then give us a call or fill out the form above.
