After reading that thread i'm worried about it hitting the spring or whatever V10sport was talking about. Is there a way to make sure it's not hitting when I put it in?

 

Don't screw it in too far. I used vinyl thread tape to keep it from leaking, and only screwed it in a little deeper then the plug that is screwed into that port. Just need it in far enough to get the tip into the fluid.

I don't think a mechanical sending unit will work there though.

 

I got it backwards sorry. The one I ordered is electrical. I thought the one like you ran was mechanical. The Z series one I looked at was. Sorry though. I got it backwards the one I ordered is electrical.

Do you have any issues not screwing it in until tight? That's going to have me worried it will vibrate out and then I will lose my fluid and not know it.

 

I just had the idea of putting a lock nut on it. Did you do that or just leave it? I'm super afraid it will fall out and I not know it and have all the fluid drain out.

 

No, I just put some vinyl thread sealer on it and screwed it in. I have no idea what v10sport was talking about over in that other thread. That is a diagnostics port, so there is no spring that gets in the way. If you've ever seen the sensor they screw in it for diagnostics, you'd see why the temp sending unit is just fine. Just measure the depth of the hole, then screw in the sending unit just further then that. Mine is very snug. No leaks, not even a drop, since I installed it years ago.

 

Ok thanks. One last question is teflon tape the same as vinyl thread sealer or should I go to get some of that? Can I get it at an auto parts store? Also would I have to worry about any of that thread sealer getting into the transmission?

 

Sorry, I meant teflon tape.
If you use it correctly, there is no risk of getting it in the trans. You can also buy some liquid thread sealer too, and it works very good.

 

When I talked to the guys at Dr Evil transmissions when I order mine, they said that the best and safest place to place you sensoor is in the pan.
I had to take the pan off drill out a hole and weld threaded bung that i could screw the sensor into.
They (Dr Evil guys) told me this is the safest place to put the sensor cause any problem (overheating) of the tranny will show the fastest in the pan (when overheated first place hot ATF will hit is the pan).
Hope this helps.

 

That's just not true. If your overheating, the pan is the LAST place that will show it. Reason is, the fluid is moving from the transmission up to your trans cooler(s) and then back to the pan before being used again. By time the fluid hits the pan, it has already been cooled by your trans cooler. Your trans could be overheating, but the fluid temps in the pan may not yet be high enough to indicate a problem.

I have proof of this in the fact that I have a sending unit in my pan as well (in addition to the temp sending unit in the front servo). I run both sending units to the same gauge in the cab with a switch to toggle between the two. Temps in the pan are 100% of the time cooler then temps in the diagnostics port. When my trans starts to get hot (like when towing steep inclines in the mountains), I see it on my servo temp before I see it in the pan - everytime.

The pan is a good place for a sending unit, but it is definitely not the place to find out the first indications of overheating.

 

I called Wayne today and asked him what he thought as well as if this sending unit was ok to use as it was about 2 times as long as the regular plug. He said that his first choice would be the pan instead of the servo port as I'd get more accurate readings but that the servo port would work fine. He thought for a minute as he said he wasn't infront of a transmission then said that sending unit should be fine.

Now my question is what temp should the gauge be reading? I mostly put it on today. I'm having issues getting the paint on the pillar pod to turn out like I want so for right now the gauge is just hanging in the truck but it's all installed and the wires tucked away. I just have to redo the paint on the pod one more time then clip it on and put the gauge in it.

I was seeing right around 150 degrees after lots of driving. Shouldn't it be hotter? I let it warm up and it went right up over 100. As in sat for probably 2-5 minutes in neutral as it hadn't been started in a while so I wanted to wait for it to fill with fluid. Then I rode about 2-3 miles and it crept up to 120. After about 5 maybe slightly more miles it made it's way up to 150. This was driving about 45 in some traffic and sitting at stoplights some. When I got home I let it idle to check my fluid level and the gauge went down a little. This is with a B&M cooler and a stock pan. Does this sound about right or is the gauge reading low?
