      Possibly that the nuetral safety switch is not disengaging when in the case it doesn't shift to gears. Replacement may rectify this fault. If the vehicle starts in gears; you may have a shift linkage problem.

      Your transmission oil may be low and you experiencing transmission overheating. Transmission oil could be contaminated or the oil vents are clogged. I recommend checking the condition of your transmission fluid and its level; change the oil and the filter if necessary and check also TPS (throttle position sensor) may be failing.

      Did you already check the condition of your U-joint (may be worn/loose/defective), driveshaft (maybe loose/bent/unbalanced), differential drive pinion (may be worn/broken pinion teeth), rear wheel bearing (may be worn/dry/damaged) and yolk shaft (may be worn/damaged)?

      Diagnose your vehicle with a scan tool to determine if there is a stored trouble code (if one of your electrical controls or sensor is at fault it will show in you trouble code). Even if your check engine light is off don’t assume that there’s no trouble code in your vehicle.

    What can I do about transmission getting to hot 200 plus degrees.
    transmission temperature gets extremely hot. I recieve a message on dash "transmission hoy" gets up to 200 plus degrees. I was told by a mechanic that it could possibly be the torque cionverter slipping. Engine temp normally runs between 196 to 210 degrees.

      The only time i will replace my TQ is when i put it to "D" my vehicle still not moves. If it does and it still gets hot, i will check the oil level first.

      So tell me, how is your tranny oil level?

    What makes transmission high temperture light come on
    transmission strains also builds up speed slowly rpm builds high before gear change
     
    • Nissan Technical Advisor
      It is possible that your transmission is overheated and you may notice a smell from the transmission after you have driven it for awhile. You may also notice some slippage or delayed shifts while driving it. When you check the fluid level of the transmission, the fluid smells burnt. These are because of; your fluid level is low or the transmission's oil vents are clogged with dirt or undercoating; your transmission cooler is bad or (if equipped) the thermostat in your transmission is bad; the wrong type of fluid was put in your transmission, or the fluid is contaminated; in worst case, there's an internal problem in the transmission. Have your car checked professionally.

    Trans will only function in 2rd and reverse
    transmission will only operate in second gear or reverse. Transmission has been rebuilt and placed back in vehicle. still will not operate reght. suspect an electrical problem, what do you think.
     
    • Nissan Technical Advisor
      It could be the gear shift linkage is binding and the fluid is low. Also the throttle cable to the transmission is broken or disconnected. It is also possible that the vacuum modulator on the transmission is faulty, or the vacuum line is disconnected. Worst case, it’s an internal damage.
