Toyota T100 ProblemsAutomatic Transmission May Not Shift Correctly at High Mileages
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.
If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.
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.

Toyota T100 RecallsToyota Recalls 1990-1998 Trucks Due to Cracked Steering Relay Rod
Toyota is recalling 1990-1995 4Runner, 1990-1995 pickup, and 1993-1998 Toyota T100 trucks because the steering relay rod may crack under stress. This may increase the risk of a crash. Dealers will replace the steering relay rod.
