You can access the Turbine Shaft Speed (TSS) and Output Shaft Speed (OSS) sensors by using a high-lift transmission jack under the transmission but you need to avoid lifting the back too high because raising it will cause damage to the sensors. Before beginning replace the rear transmission mount the transmission needs to be lifted off the rear crossmember support then the bolts must be removed from both components. The technician should lower the transmission for accessing the TSS and OSS sensors before removing the TSS sensor bolt and sensor and then the OSS sensor in the same order. The installation process requires lubrication of the OSS sensor followed by its bolt installation then similar lubrication of the TSS sensor with its bolt installation. The transmission back should not surpass a safe height because this could harm the installed sensors.
