I searched but didn't find a good answer. Where should I install the sender for a tranny temp. gauge? The truck is a 1996 auto. Is there anywhere to tap into or do I have to buy something else to install?

 

Many put it in the pan. But the best is to put it on the hotline into the oil cooler. You'll need a tee for that.

 

Does anyone have a pic of the hotline into the cooler? Which tee is needed?

i think this thread has good answers.

 

Here's a pic of how I did mine. It's been on there for the last 7 years and not a problem yet. Cost was $10.00 with supplies from NAPA store. Reads excellent and very responsive!

 

Nice job!

What temps do you see? Are you seeing anything in the 250 range until T/C lockup?

 

Thanks!
The only time I've had the temp get over 220* was when the truck was stock and converter wasn't locked climbing the Black Mt. grade on I-40. It was the first time I had pulled our 30 foot 5er and it was partially my fault for not backing out of the throttle to let it lock, plus the "not-so-great" stock TC made for lots of slippage heat. I was new to the driving habits of the auto trans behind the diesel and after talking to some other owners on techniques for throttle etiquette, I didn't have that problem again. At around 65,000 miles, I had a GB TC and VB installed along with some other tweaking after adding an Edge EZ and the trans has been flawless since. it has 137,000 miles on the clock now. I still see temps get to 200* when drag racing (depending on how long I spend with my foot on the brake and throttle at the same time) , but it cools down quickly. By having the temperture probe in the HOT line, it is giving you the temp as the fluid leaves the TC before going to the heat exchanger and then on to the trans cooler and back to the pan.

 

rattlinram,
Thanks so much for the pics. That is really what I was looking for. On my 96 though, it doesn't look like I have as much room as you to place the fitting vertically. Did you have to cut or reroute anything. Also, what size fitting is that?

 

I searched and found one of my old posts on this topic. I didn't need to reroute anything. All I had to do was cut about a 2" section out of the tubing so that adding the "T" block would not lengthen the line. I actually removed the line from completely (temporarily plugged the hole in the trans to keep fluid from leaking out while I worked on the line) which made it a lot easier to work with doing it on the workbench.

 

Thanks soooo much. I will be trying this today!!!

 

My 94 had a temp sensor in the hot line [ keeps trans from shifting to 4th & OD , until about 40*F ] , I put a 1,000 ohm resistor in the original sensor pig tail , then put the sensor for my gauge in the stock hole .
