Auto trans test plug????
The Glowshift tech support guy said there is a test port on the auto tranny in my "06 silverado that the temp gauge will connect to if it is there I can not find it. I do not want to use a tee fitting if anybody knows where there is a port that the trans fluid temp gauge will connect to please let me know.

Re: Auto trans test plug????
The pressure test port has a 1/8" NPT plug, Its above the shift shaft on the driver side, #32 in the diagram. I hope that temp gauge sender can handle pressure near 200 PSI.

Thanks, and I will check with the mfg. of the sender about the pressure at that port.

Re: Auto trans test plug????
just curious as to why you want to put a temp gauge in it since the pcm already monitors trans fluid temp and will put the trans into hot mode at like 280 or 240 or something around there and it has a default shift and no tcc lock. and some of these trucks came with a factory temp gauge and im assuming this is a 4l80e

Re: Auto trans test plug????
I am not certain about the model of the trans but if it has a temp sending unit it would be good to know but I can not find any definite info. I bought the truck to tow my travel trailer and would like to be able to watch the fluid temp as I drive. Because we live in the mountains I am a little cautious about how the trans will handle the hills. If I see the fluid temp start to climb I may have time to pull over and take a brake while it cools down. Also, the trailer loaded is around seven thousand pounds and if the trans is continually running hot I will have to upsize the truck or downsize the trailer. I would rather have a warning before it goes into hot mode rather than find out when it happens. You sound like you are familiar with these vehicles anything you can tell me about them I would appreciate.
Thanks for the info. Q |

Re: Auto trans test plug????
7000 lbs and steep grades are enough to build too much heat in an otherwise good 4L60E. GM engineers kinda dropped the ball on the "hot mode", unlocking the converter is no way to cool the transmission down, converter slippage builds heat

Re: Auto trans test plug????
if the trans goes into hot mode your not suppose to keep driving if it goes into hot mode it defaults the trans to a shift state that is ment to get you to a safe place to pull over and not do as much damage as possible but like i said if it shouldnt go into hot mode unless there is already a problem with the trans. i pull a 3000 lb race car on a 2000lb trailer plus tires and tools and compressor and generator with a 1500 4wd silverado and i live in pa and we race in pa and wv i know a little bit about hills and have no problem with the tranny

Re: Auto trans test plug????
There is a scanguage called the Aeroforce Interceptor ( http://www.aeroforcetech.com/ ) that can monitor anything that the PCM sees, and it also reads and cleares DTC's and it can do some performance monitoring. I have one in my 2003 Bonneville SSEi, and it works great. It shows Transmission Temp, along with tons of other information. That would be a better investment than a Trans. Temp gauge, as you now have a scanner/code reader to boot.
