One problem related to transmission solenoid has been reported for the 2006 Toyota Tacoma. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Toyota Tacoma based on all problems reported for the 2006 Tacoma.
When the vehicle had around 112,000 miles on it the check engine light came on and it experienced irregularities with regard to shifting. The code was ran and the shift solenoid was the issue. A new transmission was recommended. We were not informed of this when we purchased the vehicle second hand. Approximately a year later the same thing happened with the shifting and the check engine light coming on. Unfortunately by the time we took it to a certified Toyota dealer the light was off and it was running smoothly. The inconsistency of the issue is frustrating because we don't know the actual issue and if the vehicle can be trusted. The certified dealer recommends a costly transmission replacement without being able to verify the issue.
