Toyota T100 Problems
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
On vehicles with a manual transmission, worn shift bushings can cause the transmission to pop out of gear, especially when coasting down in 1st or 2nd gear. Replacing all the shift linkage bushings is pretty straight forward and not expensive and will commonly correct this concern.

I have a 1993 Toyota T-100 this is the second T-100,my first being a 1996.After having the first the only truck i am happy with is the T-100.Neither of these trucks have ever let me down,they run excellent.and off road they lead the pack.I wish Toyota would go back to building this size truck with the same running gear and motor as the T-100.Clearly there is not a better built truck than the T-100
After 13 years and 339,000 miles this truck is more like an old friend than a vehicle. It has been very reliable and still gets over 20mpg. It is one of the best values that I have ever bought.
