Hey, I have a Landrover Discovery II 2003 that had the driveshaft fall out and ruined the transmission. I have since purchased and put in a previously working transmission from another discovery. Unfortunately I am running into a problem because I cannot get enough transmission fluid into the car, only about 3 quarts have gone in. The car starts but the transmission will not engage. I have tried shifting through gears to ensure the transmission fluid was properly distributed however the car will not move because the transmission will not engage. Please help! Thanks, Lauren
