Information about rebuild ZF9HP48 (948TE) transmission
In 2011, the German company ZF developed a compact 9-speed 9HP48 transmission specifically for front-wheel-drive Chrysler and land Rover vehicles. Due to a large number of speeds, such a transmission allowed better implementation of the dynamic characteristics of the engine while providing excellent fuel economy. The new transmission turned out to be quite reliable, so repair of the 9hp48 automatic transmission was required for significant runs.
This transmission was performed in the basic version for the European market, and a modification of the automatic transmission ZF9HP48 (948TE) for North America. These transmissions differed in the spare parts and consumables used, this was due to the fact that the Chrysler company made certain changes to their transmissions.
Features of automatic gearbox ZF9HP48 (948TE)
This transmission was intended for use with engines with a maximum torque of 480 Nm. However, like most machines with a transverse arrangement, this automatic transmission was not too resistant to extreme loads. Therefore, it was installed on light crossovers or urban subcompacts. However, this transmission did not show itself at its best the Dodge Caravan with an engine capacity of 3.6 liters, it was often necessary to repair the 9hp48 automatic transmission, restore the torque converter and change the worn iron.
How it works
The lubrication system in this machine worked with maximum loads, and design with an external heat exchanger was used to cool the transmission fluid. Therefore, the car owner had to perform regular maintenance to avoid overheating, cleaning such a small radiator, removing all wear products, and coking oil from it. Such maintenance of the machine allowed preventing overheating of the transmission and wear of iron.
Oil change on the transmission was performed during major repairs or as it became dirty. Most experts recommended performing such a service with a mileage of 60-70 thousand kilometers, carrying out scheduled repairs of the 9hp48 automatic transmission, and changing all oil filters. Such work allowed delaying the bulkhead of the machine with the overhaul of the transmission.
