AT light is off, as well as others. Nothing suspicious anywhere.Big-Bird wrote:This tranmission has an oil temp sensor on the side of the valve body housing. If it misbehaves it can put your tranny into a false SAFE MODE and will change how the tranny shifts. This operates an indicator light on the dash when the heat gets too high. It may not light when the sensor isn't reading properly.
Is it possible that it's similar to glow plug temperature sensor? Page 35 here - http://www.delica.ca/manuals/L-400%20Ma ...

Lost the stupid memory stick!
Yes, OD switch works (OD OFF light turns) and I believe I checked the OD function recently and it works.Big-Bird wrote:Have you checked your overdrive switch on the end of the shifter arm? They do have a common internal break point but when they break it usually prevents OD from activiating without holding the switch down. Does your work properly?
There's no voltage in the front sensor right now, so I might try getting the resistance reading at least.Big-Bird wrote:I find using paper clips useful in the hard to reach areas such as the temp sensors. The paperclip wire can be inserted inbetween the silicone seal and the plastic jacketed wire. Just ensure the paperclip tips are only long enough to give you a multimeter contact point. If you give the wire too much of a 'tail' they might touch/ground and roast a circuit in the tranny brain.
