Robby

The P/S on my 2008 a moaning noise in cold weather but does not in warm weather. I have checked the fluid for level and foaming but everything looks normal. I question if it may be a harmonic but can't figure what would cause in in temps below 50 degrees and not above that temp. Even after 40 miles in cool weather it sound like it has low or burned fluid yet is normal in warmer temps from start up to key off. Any ideas?

Been busy with a new to us house, getting it fixed up before we move in. The Dallas area can't make up its mind if it winter, spring or summer. 90*f one day and mid fifties the next. My 08 does not like the cooler temps. Cooler temps drop the fuel mileage about 2.5 MPG. I think it because the converter does not lock up until trans and engine temps come up. Thanks for the welcome I received as a new guy

Good afternoon to the community. My handle is Robby, my real name is Johnny. I am a lifelong (will be 72 in June) Texan. I am an amateur radio operator. I own and ride motorcycles, a Honda Gold Wing and a Harley Ultra Classic. I worked for the post office for 22 years and quit before I went postal. My kids were grown so I pursued the job I always wanted and became a mechanic. The chance to buy an existing garage came along and I went into business for myself. I ran the garage for 21 years and retired at age 63. I have basic mechanic knowledge of most auto systems. I have limited experience in diesel systems. I have been visiting here for a while and decided to join and become a part of the community.

I have a new to me 2008 4dr 4X4 w/6sp auto,that got good fuel economy in warm weather. In cold weather it stays in what I perceive to be 4th for 3 to 4 miles before it will shift or torque converter lockup. The fuel mileage goes way down during this period. My overall average is down 2+ MPG. Is this the nature of the beast or is there something to be done to make it shift /lockup faster?
