Recently, my brother has been ragging on me about how the 97 Disco's tranny slips occasionally at highway speeds. I had never had this happen until today. I was getting revs, but no power output. It cleared up in about 2-3 seconds and occurred when I was accelerating onto the freeway at about 50-55 mph @ 3000 RPM. Anyone else experience this? My 95 with 126K hasn't experienced anything like this, nor had the 89 Range Rover I had before it.

Its funny though. He bought a 1998 Ford Explorer, put on 31" BFG A/T KOs, edlebrock suspension and will use the my parent's 97 Disco, completely stock, to beat the sh*t out of offroad (its the XD too - no respect). He refuses to take his car offroad, citing every line in the book. I sold my parents the Disco and now they are complaining to me.

I wonder what would happen if I repeatedly switched from Drive to Reverse on his Explorer @ 3000 RPM? Its probably what he was doing to the XD.

My father, being more than a loyal Ford fan, tells me off every little problem with the vehicle. Oh, and what happened to the brand new (back in the day) 95 F-250 7.2 diesel the first time he went to lock the diff....BANG!!!!!! $5000 repair.

P.S. I just got a msg from my Bro saying that he is putting a TJM T15 bullbar (very similar to the ARB). I asked him if he was going to do offroading now or just drive it on road. He said on road. I told him to lower his explorer 2 inches and get 20inch chrome rims.

Yeah,
your brother is pretty smart. I wouldn't trust an exploder off road either!
Check your fluid level.

If it's at highway speed (over 50 mph, and I'm supposing not wide-open throttle), it may be torque converter clutch slippage. Usually those things never wear-out, but it's not impossible. And sometimes the clutch solenoid can go bad and intermittenly release the clutch, but that doesn't sound like what you're describing. Hopefully it's probably just a fluid level thing, as Clint suggests.
