does the vehicle have a manual ? i would check the halogen wiper fluid first.

I think in that model and year its sodium wiper fluid not halogen dude.:confused0006:

maybe your linkage needs to be adjusted.. mine did that for a bit till i bent it with my driveshaft when that decided to snap, now it works fine :D

The linkage is connected to the body under the shifter. If he has a body lift in it could affect it. you can get a shifter relocation bracket which moves the linkage off the body.

Oh and you guys are both wrong, the 2000's use nitrogen alloy wiper fluid.

I'd LOVE to see a '00 Grand with a body lift....I'd call Ripleys if it was ! In any event, sounds like there's a linkage issue between shifter and t-case....I'd look there first.

Shows what I know about station wagons, should have read the whole GRAND thing. I forgot for a minute that people wheel those cars. I would still check the linkage though

I'd say its not fully engaged, rather than slipping out it was never actually in. Engage it roll a touch and keep pulling up on ther shifter, hopefully you'll get the clunk that it is engaged. Used to have the same issue with my 98 GC.

with a lift it probably has a Tcase drop in it which will throw the shift linkages out of alignment. Check the linkage for adjustment the link between the floor shifter and the bell crank is the adjustable one also make sure the bell crank is still in the bushing on the transmission pivot bracket, you might need a relocation plate for the bell crank if it is on too much of an angle from the tcase drop.
