Transmission fails to go into gear. This is a common problem with the aisin AY6 6-speed manual transmission in the Tacoma from what I see on internet forums. A danger results in crossing an intersection, merging or many other unforeseen incidents where it is nearly impossible to get the transmission into the next gear. In my case, it is particularly difficult for the 1-2, 2-3 shifts and reverse. I have taken my truck to Toyota numerous times and in short was more or less told to "take a hike" and sometimes in a manner than was not the most pleasant means. Throwout bearing also squeaks since brand new (tsb posted?), and Toyota's only action is to replace it with another bearing that will only squeak again anyway. I do not get why I have to constantly take a truck that is barely driven in for a complaint. Something is not right, I (we) paid for a Toyota and their reputation, but this was my last purchase from Toyota ever. It seems that to get anything replaced on every vehicle affected by these profound issues, that someone must die again as with the gas pedal incidents.

Powertrain (front differential) front vibration around 30~45mph. The vibration goes away when 4WD is engaged. Other owners have claimed premature wear on front differential bearings (driver side).

When driving at high speeds (above 50 mph) there is a whining coming from the drivetrain. I have an 06 Tacoma reg. Cab with 4X4 & 5 speed with less than 500 miles. Truck has made the noise since purchase date. Service tech thought noise was normal or may go away eventually. I then test drove a duplicate truck off dealer lot with service tech & there was no whining. They then conceited that it was not normal. They have replaced the transmission, transfer case & driveshaft with no results. Fortunately dealer does recognize the problem however they can not give a solution. Dealer has provided me with loaner car while problem is being worked, but they have had the truck 24 days of the approx. 70 days I have owned truck.

My 2006 Toyota Tacoma makes a loud clanking noise upon takeoff. The noise comes from the rear of the truck. A representative from the dealership states that this is normal for the Tacoma. If true, this is not good news.
