Occasional stutter on highway

[Ben Geller]

I was on the highway today in Manitoba, there was lots of snow and the roads were icy. When driving in cruise 2x, and once with foot on peddle the engine or drivetrain stuttered. It was quick, made the truck shake a little, and then normal again. RPM's didn't fall, it wasn't during a shift, and I wasn't in 4x4. It has never done this before, and after returning to the city and driving around, it didn't do it again.



Any ideas?

sounds like it was just slipping on some ice?

Is the Trac that light that it could slip when in cruise? I was doing 50MPH at about 2100 RPM.

 

[Matt DeFina]

yep,

I've experienced the same on the one day it snowed here in ATL

never did it any other time.

Yep. Mine does it all the time. And I have 210 pounds of sand over the rear axle and never less than 1/2 of a tank of gas.

It feels like the tranny slips when it slips on the ice?

you should never use the cruise control on wet or snowy conditions, if it does start to slip it may want to hit the gas to maintain vehicle speed, then you could loose control.

I took his use of "cruise" to mean when driving at a highway speed, not necessarily to mean when using cruise control.



Yes, ffs, it sort of feels like the transmission is slipping for a split second.

The highway had just been plowed and sanded. So cruise was fine at the time. And I was referring to cruise control.
