    Trans Temp Sensor Problem

    Installed an Autometer Trans Temp gauge in my truck yesterday, along with a boost and a pyro gauge. Everything works great except the trans gauge never moves off of 100.
    The only thing I can think of is the sensor isn't grounded because I replaced the stock pan with a Mag-Hytec pan a few months ago and its aluminum.

    Thoughts/suggestions?

    Probably not the response your looking for but love the setup! That’s my plan with boost, backpressure and fuel pressure off a fass pump.

    Aluminum is a grounding metal too. There is no reason why that pan wouldn't be grounded unless you used rubber washers. I would think the sensor is bad. Usa a jumper from the brass body of the sensor to a good ground and see.

    I know allot about allot. It's a competency curse. It's more like I've done allot over the years, wore many hats, been beat up allot, and am a good engineer. Don't ask me about insurance, real estate, stock market or program the VCR. And I suck at valve adjusting. Don't ask me why, I can't seem to do it right

    Yep, That's where i have the sensor installed. I'm not sure what the problem is. I'm traveling right now, so no time to troubleshoot it.
