    Has anyone else had troubles with their 6 litre trucks not shifting into 5th or 6 th gear when the weather is cold while pulling a trailer. my truck will not come out of 4th gear while pulling my enclosed cargo trailer ,rpm is at about 3200 and will not shift if it is below -10 celsius .
  2. Never pulled my trailer in the cold. I have not experienced anything like this on my truck driving it in -30c.

    Father in law has same truck as you and never had a problem either until we tried it in the cold, normally he only ever pulls in summer and everything works fine. Mine works fine without trailer and when it is above -10. Will have to wait and see next winter if it does it again.
