Explorer 4wd problem

I have a 2002 Ford Explorer Eddie Bauer 4WD V6 in the UK, and have covered

36K miles. A few weeks ago I noticed while driving that both the 4wd Hi and 4wd Lo dash indicators flashed on at the same time. They flashed 1 second on 1 second off 3 times then repeated this every 2 mins for about 10 - 15 mins. After stopping the car and restarting the engine I have not seen this problem till now. But now when I start the engine the speedo indicates full scale for 1 second then back to 0. I can hear what sounds like the heating control baffle motors operating back and forth. Also if I try to select drive the car jolts into gear as if LOW gear. If driven at 30mph the revs appear normal for this speed, but the speedo indicates about 90mph. I live in the UK and no garage has a clue on this model. Can anyone tell me whats wrong?

I had a similar problem on my '98. I think it's something to do with the speed sensors (there are 2 located on the transfer case) I got underneath, disconnected the sensors, then reconnected them, disconnected the battery for 10 mins, reconnected it and hey presto no more problem. (and that was last September)
