Hi, My Tacoma meets the same thing as this but small different. It can not shift to upper gear when it is cold engine. After heat up. the temp meter is pointing to the mid scale position it can be changed to higher gear by moving the gear control rod to lower location at 2 level and than pull it up to D level. it will goes to higher gear, but if want to stop in front of stop traffic sign, it will change to lower gear after I pass the stop traffic sign I need to move the gear control rod to lower at 2 level and then pull it up to D level in order to make it at higher gear so that engine would not rotate at high speed to keep it run at 30..50 miles/hour. Yesterday night I can not make it to higher gear even doing this action on it. I want to know what & which parts get problem to create this problem.
Please any news please email me at email@example.com & also reply this posting.
