One problem related to clutch pedal/linkage has been reported for the 2007 Toyota Tacoma. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Toyota Tacoma based on all problems reported for the 2007 Tacoma.
At highway speeds, during upshift from 4th to 5th or downshift from 5th to 4th, with clutch pedal depressed, engine rpms do one of the following: 1)remain constant, and then increase for several seconds before starting to decrease, 2)remain constant for several seconds, and then decrease, 3)decrease very slowly (far to long to execute a "clean" shift). While 2) and 3) are more of an annoyance likely due to poor engine control software, 1) is a serious safety concern in that engine speed (and vehicle speed) continue to increase despite the clutch pedal being depressed. "goosing" the accelerator does not appear to have any effect--the engine rpms wait several seconds before falling. In addition to the safety issue, you also wind up with a lot of clutch slippage because you are letting the clutch out while the engine/transmission are still engaged at a high rpm.
