HEY POBLO, MY 13 SPEED TRANNY ON 2000 VOLVO 770 IS OVERHEATING.
I DON'T KNOW WHAT IS PROBLEM WITH IT. A FRIEND OF OURS ONE IS DRIVING IT AND ITS TELLING THAT THE TRUCK TRANNY IS OVERHEATING GIVING HIM ALARM AND CHECK LIGHT IN CIRCULAR LIKE.

 

HI EVERYONE, I HAVE 2000 VOLVO VNL 770 WITH CUMMINS N14 AND A 13 SPEED TRANNY. IT IS DRIVEN BY A FRIEND OF MINE AND HE IS TELLING ME THAT THE TRANSMISSION IS OVERHEATING GI ING HIM CHECH LIGHT AND THE DEGREE OF HEAT, 309. THAT IS HOW HOT THE TRANNY GOIN.
I KNOW IT CAN BE CAUSED BY SEVERAL DIFFERENT THINGS SUCH AS; LOW OIL PRESSURE or low oil, radiator not working anf of course sensor not working properly. what else do you guys thing can cause?

 

First and foremost check the oil level.

 

hi to all

transmission is oil cooled

is it Eatom 13st?

 

I am going to disagree. Location will have a big influence on if the speedo sensor will come out. I maintain a fleet of salt/plow trucks and we run the factory speedo sensors plus another one to control the automatic salter. The old style sensors were internal and threaded into the rear speedo housing then jam nut to secure this style I have never had a breakage issue. The new style sensors are external and slide into a metal tube and secured with a small bolt. In salt conditions the sensor gets crushed due to rust forming between the plastic sensor and the metal tube. When you go to get the sensor out it will usually twist off and the body of the sensor stays in the tube. When this happens you drill, chisel it out piece by piece until it is all gone. I would say about 50% of the time the sensors will break very common issue in winter/ salt locations.
