    Discovery II Transmission Problem?

    I was driving my Discovery II today pulling a light trailer. After about an hour and 100 miles the tac started bouncing between 25K-3K, like the tranny could not figure out which gear it wanted to be in. Then pulling onto an offramp the hill descent control light, Traction control light, sport mode (s) and (m) lights came on. The "D" indicator in the dash and on the gear selector were both blinking. I parked the trailer (which was only carrying a small Nissan motor) and shut it down. Restarted and the buttons went away.

    Any thoughts on what caused this ould be great? Thanks gentlemen, I look forward to hearing what you have to say.

    Other then checking the fluid level and quality, in other words is it red or burned and brown? Do you know how to check the fluid level without spilling a bunch on the ground?
    After that, I would go to you local parts store and have them read the voltage, should be between 13.6 and 14.4, lower then that and it can cause problems.
    By the way, do you have a check engine light on, if so get the codes read and get back to us.
    Let us know what you find.

    I had the same issue on my D2 at 90K, and my tranny fluid was very dirty. Not sure of the miles on your D2, but if you have never changed the fluid you may want to as an attempt to solve this problem and to get one thing off your general maintenance list of things to be done. Note, no tranny fill tube under the hood, but on the front of the tranny pan. I did the tranny service, and dropped the pan and cleaned it and the magnet inside on the bottom of the pan, then did the fill with some helpful notes from the forum. Drove it 500 miles, and then drained and filled again to get a more rich mixture of good fluid as Mike suggested to me since mine was so dirty. Solved my problem.

    As others have said, also could be battery/alternator issue as well.

    Smile Thanks guys!

    The Rover has 88K on it. I have not yet changed the fluid in the transmission. I will have that done this week. Thanks for your input. The check engine light never came on, just the lights flashing that I indicated. Again, thanks for your input, I appreciate it!

    At that mileage, you usually don't need to change the filter, why not to a drain and rwefill and save your self some money?
    Also go get you voltage checked.
