I have a empty spot for a gauge and im goign to put in a temp gauge for the trany, the 6 speed dont really need it but cant think of a better gague to put in, where can i get a temp sender to put in the trany and where to install it?

 

im not tryin to step on your toes man but y dont ya just buy the correct amount guage holder and sell the one on ya got instead of buying a possibly unessesary guage......thats just my $.02

 

I installed a temp gauge in my 6-speed tranny, I drilled one of the side covers and welded on a threaded bung for the sender. I did that when Iwas changing the tranny fluid. After a year of monitoring my tranny temps, I then installed a pair of fast coolers, they have a port for the sensor.

If you tow a lot, and if you tow heavy, the tranny temps WILL suprise you, they certainly suprised me, I am glad I installed the tranny gauge. I now know why the recommended fluid changing levels are at 15K, the tranny fluid DOES take some heat abuse.

I don't mean to be rude Hudge, but once you actually get to see what tranny temps ARE the gauge is NOT un-necessary - I speak from experience.

I installed a 4-gauge overhead pod for temp gauges - oil temp,tranny temp, f & r diff temp. The considered 'more mainstream' gauges I have in a dash pod - fuel press, rail press, boost, and EGT.

Since I have an exhaust brake, I decided to monitor it as well, I have a brake press gauge in the single SRT-10 a-pillar pod.


Usually the temp sensor/sender comes with the gauge packaging.

thats exactly what i did. i just don't have the gauge yet. i plan to also run a rear end and tranny gauge due to towing. i'm glad to see that it does come in handy like i expected.

 

I too added a gauge to my G56, exactly in this way. I also added a rear diff. temp gauge. Man is it ever an eye opener while towing how hot these oils actually get.

 

Real interesting to watch the tranny and rear diff temps when towing a heavy 5th wheel. My rear diff temp seems to run higher by 20-25 degrees. Maybe placement of the sensor or the trans cooler is actually making that much difference?

Just more info to help if you have to troubleshoot. Glad I got mine.

 

What are some of the temps you see?
I've found my shift quality degrading awfully quickly and have been thinking it's a matter of changing fluid often.

 

I thought the G56 was recommended at 50k miles I don't have my manual right here to look yet.

After reading this I think I will also put a gauge in my tranny.

I would also like to know what you guys are seeing for temps not towing vs towing.

 

5sp Man trans unloaded 140-150, rear dif 150-160
loaded trans 160-170, rear dif 190-200

 

While towing my ~8000 lb trailer with flipped axles and 2 quads on the deck of the truck into a head wind I've seen 215* on both the tranny and rear diff. Usually though they are anywhere from about 170-190* depending on terrain and wind. Empty I can see 160 on the the tranny when its hot out. (80* or warmer). The diff is about the same.

I too have a noticed a shift quality difference when the oil is hot, but once it cools down a little bit it goes back to normal. I change the oil once a year for cheap insurance and it always looks as good coming out as it did when it went in.
