Transmission slipping?

[thebigfarmer]

Well today I was driving and I accelerated to 25, then the wheels weren't spinning but the speedometer and tach would still go up. I let off the gas tried again and the same thing happened. Then I tried after that and it was fine. Got to my destination with no further problems. Any ideas?

Speed sensors bad? Check engine light? Do you feel it slipping? More info is needed to really help you.

No check engine light, I couldn't feel the truck moving from side to side like it usually does when the wheels spin, so that's why I was asking.

Speedo wouldn't go up if the trans is slipping.

[thebigfarmer]

That's exactly what I thought that's why I asked, so I would have had to have been spinning right?

Was this on ice or snow? If so then yeah, you had wheel spin.

Most likely wheel spin. When it gets super cold or a slight amount of black ice my traction control kicks in and I have no idea why. I realize that the cold makes the tires harder than usual and the pavement is cold as well, so less traction on dry pavement. a slipping trans would have the engine rpms go up and the speedo would read the same. (and then the truck may lurch as the trans grabbed)
