One problem related to transmission noise has been reported for the 2000 Toyota Toyota Truck. The most recently reported issues are listed below.
2000 tundra with 60,900 miles on it. (right - 900 miles out of warranty. ) overdrive started making noise when engaging and whine while driving. Out of overdrive transmission sound fine. Brought to dealer immediately and they had district rep drive it. Determined that the whole transmission needs to be replaced, but they will not cover any of it. Called the manufacture and they will not do anything for me. Neither the dealer nor manufacturer will get me in contact with the district manager who made decision.
