How to service and repair the Transmission Speed Sensor on 2003 Toyota Tundra?

Question

Accepted Answer

Service and repair of the transmission speed sensor starts with propeller shaft removal before proceeding to remove the No. 1 vehicle speed sensor and speedometer driven gear and the No. 2 vehicle speed sensor. The transmission needs to be slightly elevated through a transmission jack while it rests on a stable support that lets you remove it from the crossmember. The service starts with removing 4 bolts from the rear mounting side of the engine rear mounting insulator before taking out the 4 nuts, bolts, washers, and crossmember. Start by removing the 4 bolts and engine rear mounting insulator from the extension housing and continuing with the removal of the 6 bolts and gasket and extension housing while using a plastic hammer or wooden block to help the extension housing come loose if required. To work on the 5VZ-FE you need to utilize a snap ring expander to take out the snap ring followed by removing the speedometer drive gear along with the ball. The procedure for the 2UZ-FE entails a snap ring expander for snap ring removal after which you should remove the speedometer drive gear. To remove and install the snap ring of the sensor rotor first apply a snap ring expander tool then use the key with the sensor rotor. The installation requires first using a snap ring expander to place the snap ring followed by insertion of the key along with sensor rotor. Use a snap ring expander to install the snap ring when working on the 5VZ-FE engine with a speedometer drive gear and ball in place. The speedometer drive gear requires installation before placing the snap ring with a snap ring expander tool on the 2UZ-FE sensor. The extension housing must receive threads of part no. 08833-00080 Three Bond 1344 Loctite 242 sealant or equivalent before the installation of a new gasket with its installation on the case using 6 bolts that reach 36 Nm (370 kgf-cm, 27 ft. lbs.) torque while noting that the two lower bolts are shorter. Add the 4 bolts onto the engine rear mounting insulator and torque them to 65 Nm and then add the crossmember with its 4 washers, bolts, and nuts torqued at 72 Nm, followed by torquing the 4 bolts on the rear mounting side to the engine rear mounting insulator to 18 Nm. The last step includes fitting the No. 2 vehicle speed sensor and speedometer driven gear followed by installing the No. 1 vehicle speed sensor and propeller shaft. Then, fill ATF while verifying the fluid level.
