How do you replace the transmission on a hyster forklift?

To replace the transmission on a Hyster forklift, first ensure the forklift is safely elevated and secure it on jack stands. Disconnect the battery and remove any necessary components such as the drive shaft, hydraulic lines, and electrical connections to access the transmission. Once unbolted, carefully remove the old transmission and install the new one, reassembling all components in reverse order. Lastly, refill any fluids and check for leaks before testing the forklift.
