    The manual says once a year.
    I don't know when it was changed last.
    I have NO problems shifting from 1st to 2nd or any gear for that matter, cold or hot. I have read many threads on this subject and will use Red line 75~90 NS if I change it.
    I change my engine oil once a year. Timing belts were done at the time of purchase Jan 2005. Did Birdman's fuseblocks summer 2006. Serviced the
    hazard light switch, since turn signals worked only when I did NOT need them.

    So should I change the trans/diff oil?

    Well if it hasn't been changed in the last year, then I would say yeah, change it.

    Change it. Once a year or every two years regardless of km's IMO. :):)

    It is really no more time consuming than performing an oil change. Get to it. ;)

    Since you don't know when it was last done, I'd change it. If you use the redline oil, I'd say check the level every year and change it again in 5 years.

    Most gear oil doesn't need to be changed as often as you think as it doesn't really wear out. Condensation problems would warrent a change, if it looks milky do it now but if its clear and clean leave it be. My dually Dodge with six speed manual trans. comes from the factory with synthetic in the box and the owners manual says it is not necessary to change it.

    My personal belief is that F went to the change-once-a-year recommendation just to make sure that the garage queens got some oil on the non-submerged half of the gearbox internals at least once a year. If you're driving regularly, I can't see doing it every 2 years as a problem.

    Use the redline it makes my car shift way easier. I am noticing a howling at about 40 mph I never heard before. Steve, you said you were getting a chattering, since I have no experience I am not sure what that would sound like. I have no sound at slow speeds turning tight corners, but am perplexed by this odd noise?

    The LS clutch chattering (or more like a "groaning" at low speeds) only occurs when the rear wheels are spinning at different rates (i.e., going around a corner) so that can't explain your 40 mph noise.

    Far more commonly caused by hub carrier bearings.

    Wow, I hope not I have only put less than 10,000 miles on them and only driven through one river on a FCA nightmare drive! This sounds like it is coming from the exhaust actually. Everytime I am back there, I take off the trans heat shield and think that when i put it back on the aluiminum header cover moves leading to some kind of vibration, but not sure that is the case. I am very sensitive to ay wierd sounds which tend to drive me crazy. I had a metal vibrating sound bugging me turns out it was the rear seatbelts vibrating together!
