transmission Sensor

[Dave04]

Where does everybody put there transmission temp sensor? Is the dip stick wrap any good?

 

[Edgemann55]

Output line to cooler. Different ways to go about that. I went with the one from Mass Diesel which replaces the whole line it has a fitting on it for your probe. This way you are measuring the hottest fluid from the transmission.

What about the dip stick wrap from genos?

port in front of dipstick

I put mine in the port just in front of the dipstick. Gauge takes about 15 minutes to warm up.

Get yourself one of these and attach it to the front / output line of the transmission. Works super slick.

Your trans will already tell you if the temp exceeds 265 degrees in the pan with a dash light. A sensor in the pan, dip stick tube, or a trans port is totally useless and redundant to monitor what is needed.



You want to monitor the amount of heat generated when the TC is in fluid coupling to adjust driving to minimize those temps. The only way to do that is put the sensor in the output line of the cooler system before any heat exchangers.



In lockup the cooler line temp will generally be within 5% of pan temp. In fluid coupling it can easily double the pan temp. By the time you read a problem its already too late.



Monitoring temp at the cooler output allows you to select a gear and lockup mode to keep the trans healthy. It will also indicate how efficient your cooler is working and indicate whether you have a developing problem in the trans drive train.

So your saying the a wrap on the line to the cooler is not going to help me at all?

I don't think the Accutemp is all that accurate. Personal opinion but some find it useful.



Considering the range of temps I see in the cooler line as compared to the pan, there is no substitute for IN the cooler line.



As I said, the trans has a temp sensor in the pan that will alert you to when the pan temps get over about 265 but that means you are frequently pushing temps of 300 degrees or more at the TC. The fluid tends to break down faster the more times you get the temps up so keeping the major heat generator in check is the key.



My opinion and idea how to use a gauge, others have different ones. Just giving you my take so you can make your decision with enough info.

Where is the stock pan sensor?

Where is the stock pan sensor?

Part of the sensor pack on the valve body.

Where is the stock pan sensor?

Mounted on the right front of the valve body submerged in the returned "cooled" fluid.

The Geno's part I linked to works for me, I filled the cavity with antiseize so the sensing bulb does not set in an air pocket. My ISSPRO gauge matches what I have seen with my infrared temp gun where it is mounted.
