    For an 86 with a 700r4. I don't know the first thing about them, how does it install and where can I buy one? Also, what would be considered a normal tran temp operating range.

    Thanks

    The last one I had came with a 'T' that spliced into the hard line from the tranny to the rad. The 'T' had a sender unit on it that was wired direct to a gauge. Think I got mine from Summit. Don't remember the op. temp as it was on a previous truck and I don't have one on this truck...yet! /forums/images/graemlins/thumb.gif

    The one I have installs right in the side of the tranny pan.

    I used a drain plug kit because it threads right into the plug on mine.

    From what I've understood, about 30 degrees below what your engine coolant runs is what your tranny should be at.

    Hope that helps ya some. /forums/images/graemlins/thumb.gif

    i have always been told to keep tranny temp under 190. i ran a temp gauge on my ram and it stayed around 170 to 180 with a stock cooler...

    from what I understand you can even run a regular coolant temp guage for tranny temp. Just install a fitting into the tranny fluid pan and hook it up.

    Have one in my 91 sub.. (B&M).. here's a little more info on it.. ( go thru Home >Transmission Products >Transmission Temperature Gauge ) and then Tech Info....
    B&M
    If you look close @ gauge, it shows the 'acceptable' range.
    (added a whopping cooler to mine, and seldom get to 150 now on the return fluid temps. Going to add a 2nd one to get the 'exiting' tranny temps to see how effective it is.

    I installed mine in the pump pressure test port on the drivers side of the tranny. It is a 1/8 NPT just like my trans sender (autometer). At this location it will read the temp after the pump but before any of the coolers. It makes for a very clean install and you don't have to use any special adapters or weld a fitting into the pan. My temp runs about 175* with the factory and aftermarket cooler.

    i got the autometer performance series trany gauge. the sender comes with a whole bunch of brass fittings so it can be screwed into many different size holes. the fittins let the sender screw into themselves then you screw the fittings into the right aplication. i drilled a hole in the side of the pan and sandwiched the pan inbetween the sender and a larger fitting. then i jb weilded the outside part of the pan. when yo do this be sure the sender has a good ground if it dosnt it will read wrong or not read at all.

    That was on my s10 with 700r4. The TH350 is in about the same place at the transition from the body to the bell on the drivers side. The TH350 might be a 1/4" NPT so you might need an adapter...I don't remember. Most of the other test ports are farther back and clumped together so I don't think there is any way to confuse them.
