• Q: How to service and repair the valve body assembly on 2007 Toyota Tundra?

  A: The first step prior to servicing the valve body assembly is to disconnect the negative battery terminal cable but wait for at least 90 seconds after switching off the ignition so the navigation system can preserve its memory and system settings. Start the process by draining automatic transmission fluid before taking out the automatic transmission oil pan sub-assembly with the valve body oil strainer assembly. Activate the transmission valve body assembly removal process starting with cable removal then extraction of bolting, detent spring cover, detent spring alongside the 19 bolts from the valve body assembly before proceeding to separate the check ball body along with spring while maintaining careful prevention of dropping them. Follow the required procedures for shift solenoid valves SR, SLU, SL2, SLT, SL1, S1 and S2 to perform removal and check measurements of resistance and operational noise. The test results must meet specifications to avoid replacement of any solenoid valve. Follow the torque specifications while mounting shift solenoid valves S2, S1, SL1, SLT, SL2, SLU, and SR into their respective positions but apply ATF to new O-rings before installation. Complete installation of the transmission valve body by placing both spring and check ball body correctly then insert the manual valve pin followed by bolting it with 19 bolts while installing the detent spring cover and detent spring. Reinstall the transmission wire followed by valve body oil strainer assembly and automatic transmission oil pan sub-assembly, then reconnect the cable to the negative battery terminal before filling the transmission with fluid. Systems requiring initialization should be done after cable reconnection.
