My service manager borrowed my truck yesterday to deliver a tractor. He had to pull it up the mountain. He said that at one point the transmission light came on. He pulled over and waited a few minutes untill it went off. It wasnt in overdrive and he said it pulled fine. The light never came back on. Should I be concerned about anything here?

 

I'd be concerned about why my boss would ask to borrow my personal vehicle to make a delivery.
My Truck, I drive.

Check the fluid to see if it's dark colored or smells 'burnt'.
If so, I'd have the fluid and filter changed on HIS dime.

 

Well our 1 ton was in the shop and I needed a tractor delivered. The fluid smells fine but it probably is a little dark.

 

If it's driving OK, I'd still ask to have the fluid and filter changed.

 

I believe that light is set to come on at 250 degrees. Way too hot in my opinion. I'd definitely have it changed

 

I pulled another load today and everyting was fine. It is going in first thing monday morning for a fluid and filter change.

 

my light comes on about 200 degrees when compared to my trans temp gauge

 

Good to hear.

 

Got it back from the shop yesterday evening. No residue in the pan. Should be good to go.
