Toyota T100 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Toyota T100

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.

At higher mileages (125,00+) the Engine Coolant Temperature Sensor may intermittently stop working, especially when the vehicle is fully warmed up. This can result in illumination of the Check Engine Light and/or an engine stalling problem.

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.

I purchased my '96 T100 last Feb. with 312K (now @ 327K). The first thing I did was purge the trans with synthetic atf (I had great luck doing this in my '81 pick up with a 3vz/auto from an '88 runner with over 300K). After driving for a few months I decided to plow with it this winter. I am amazed at how much pep this truck has right off idle, it does however seem to lag at around 65mph (i...
