2005 W900L
Had a 10 speed in it. Put in an RTLO 18918.
Temp is always very hot. 300 +
Should I put in the temp sensor from the 10 speed to make sure the resistance is correct ?
18 speed temp hot

I would start with that if it'll fit without interfering.
Can shoot the housing with an IR temperature gun too to confirm the temperature.
300 is HOT!!!! If its running at that temperature it'll be burnt up in short order. Anything above 250 you're cooking the oil. -
18 spd usually requires a cooler. Did the 10 speed have one?
-
The 18 speed came with a water style cooler.
I stopped at Kenly and put my hand on it when it was showing 300 degrees... It was hot but not 300.
That’s why I’m thinking the sending unit should match the truck gaugeuncleal13 Thanks this. -
I think I’ll take my IR gun with me on the next trip.
Good idea,,,, -
Does it always read 300? Does it start out at 300 or slowly climb up? Does it fluctuate during the day?

Where does the gauge needle park when key is off?
On the Peterbilt gauges they normally park around the 150 degree mark when key is off. Turn key on and it will move needle to read actual temp if above 100. That is one way of knowing if the gauge or sender is still working correctly.
I’m just not sure if the KW’s do the same thing.
I’m like everyone else and agree the sender in the trans does not match the gauge in the dash. Easy fix. -
After an hour or two at the truck stop it's down below 140..
Kenworth's seem be ohm sensitive on most of gauges -
Going to call Kenworth tomorrow and get a new sending unit that was in the original 10 speed....
