Common Reason behind Tacoma 6 Speed Manual Transmission Problems
Erratic Shifting / Loss of Forward Gears: If you’re experiencing transmission problems like slipping, erratic shifting, or failed gear engagement, the causes could range from a failed solenoid to a torque convertor issue.
Another common problem is overheating: This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.
Loss of 5th Gear and/or Reverse: Another common problem is an inoperable fourth or reverse gear. These issues are often caused by design flaws in the Reverse Boost Valve, channel plate, and stripped splines on the 5th gear clutch hub shaft.
Premature Clutch Wear: Symptoms include hesitation before accelerating and jerking during gear shifts. This is a common problem because many Tacoma owners allow the fluid in the master cylinder to get too low, causing air to get into the Tacoma’s hydraulic clutch system. This messes up the pressure applied to the clutch system, leading to premature clutch wear.
