its been about 6 months since i checked it. i take it around the block. leave it running in park go to check the fluid and its full i end up losing about a quart could have lost more if i didn't plug it. then tried it in neutral same thing. is it supposed to be in drive or what? i cant figure out where all that fluid came from.

 

Running in park, even LR wouldnt tell you running in drive.

 

You're supposed to check the level with the engine/gearbox at ambient temperature.

How To Check And Refill Transmission Fluid On Discovery 2 And Range Rovers

or page 10-18 in the workshop manual.

 

The quickest way I have found is to jack up the vehicle onto axle stands underneath front and rear axles so the wheels are 2 inches clear of a level garage floor. Start the engine and with your foot on the footbrake move the auto stick through all the range of gears a couple of times and then return it to P park. Undo the filler/level plug and top up the Dexron 3 asap until it overflows slightly. Re-insert the plug and run through the gear range again with your foot on the footbrake then return to P park and recheck the ATF level again and top up if necessary. Job done. Time taken about 30-40 minutes.
