how did you guys mount your sender on your trannys? I thought about putting it in place of the factory one, you know the one that causes the downshift when the tranny gets to like 800 degrees... *laughs* anyway just fishing for ideas..

I used a T inline just inches away from the factory sender, right betwen the tranny pan and engine oil pan.

 

I removed the stock sensor and used that port for my tranny temp gauage. The stock sensor can just be zip-tied up out of the way (but leave the wires connected). The only problem I had was the probe was a little long for that port, so I had to get a couple pipe thread fittings to space it out a little. It works great.

 

what exactly does the stock sender do?

 

It's used in the overdrive stuff. It'll prevent OD if the temp is too high

Here's my setup

just wondering what kind of temps you guys are getting that have it mounted in the line at the stock probe location?

 

I usually see 150-180 unloaded on the highway cruising at 70mph and 180-200 towing a 5k trailer at 70mph. Haven't had to pull any long hills yet so that loaded figure might go up some.

 

When moving in ambient temps around 90*, I see 170-180-190. When I stop, it gradually comes down. Haven't observed towing temps yet.

Yep, that's what I did too. I have seen 260* on a hot day towing and in a hurry.

 

What is the max operating range for our transmissions? Anything over 240 is a red light?

 

DC says that the sensor will kick you out of OD and/or prevent the upshift into OD if the temp reaches 275*F at that point you are pretty much cooking parts...sorta deep fryin 'um so to speak. not cool at all...

If temps are getting to be a problem, >245* try running synthetic. The ATF looses it's lubricity and protection quicker as temperature rises above 245*. Synthetics will run ok at higher temps, plus they have less fluid friction which helps lower overall temperatures.
