Analogue Transmission Temperature Guage

Digital Transmission Temperature Gauge

Climbing that last hill and all of a sudden the transmission temperature light starts flashing…

If only you had some way of monitoring your transmissions temperature

The most common cause of automatic transmission failure is heat. Excess heat can build up due to many different reasons. These reasons can include:

  • Slipping clutches in a well worn transmission
  • Low fluid level in the transmission
  • Lack of cooling capacity
  • Driving style
  • Excessive power increases
  • Towing heavy loads up ranges

While all of these reasons can be addressed, some of them are easier said than done. But without having some sort of monitoring system on the transmission, how do you know you are making your situation better or worse? Is your transmission actually overheating? Is the problem coming from somewhere else?

This is why we highly recommend that ALL vehicles fit one of our Transmission Temperature Gauge Kits to give you real time feedback. Most importantly you will be able to understand what is ‘Normal’ for your transmission during your normal day to day driving. When you put extra strain on your transmission you will be able to see how your transmission is handling that extra strain and how long it takes to return to ‘Normal’ afterwards.

If the transmissions temperature doesn’t return to ‘Normal’ or continues to climb during the extra strain, you have the ability to adjust your driving style to give the transmission a chance at recovering. If nothing works and you reach 130° C (265° F) you need to start looking for a place to pull over, put the vehicle in Park, leave the engine running and allow the transmission to circulate the fluid and cool itself down. Without having a Transmission Temperature Gauge Kit most users will continue to drive without changing their driving style until the automatic transmission overheats completely and potentially stops altogether.

Having one of our Transmission Temperature Gauge Kits will give you the confidence to handle all situations and more importantly, give you the greatest chance of preventing that dreaded call to roadside assistance.

What makes a good Temp Gauge?

Fitting a Transmission Temperature Gauge can be easy if you have the right information. Knowing where to put the temperature sensor so that it picks up on the hottest temperature point is the most important factor in having reliable feedback.

Most transmissions have two cooler lines that allow the fluid to flow through the oil coolers. One will be a ‘Hot’ line with the other being the ‘Cold’ line. The ‘Hot’ line has oil flowing from the transmission at it’s hottest point and this is what we want. Using the ‘Cold’ line is going to give you false readings as this is oil that has been cooled already.

We have seen the occasional gauge with the sensor drilled and fitted to the transmission pan. This is quite frankly pointless as you are getting a delayed temperature due to the cooled oil mixing with previously cooled oil. This can result in a delay of many minutes which is potentially disastrous for your transmission as you may continue to push the transmission when it has already reached its critical temperature.

All of our Transmission Temperature Gauge Kits come with replacement cooler union fittings for the ‘Hot’ line with the temperature sensor already fitted. We also use high temperature silicone insulated wire for the sensor connection as it is quite often run through the engine bay and close to the exhaust system.
