Hey there folks, my make is Weyland I have a good running 04 freelander. Recently the service engine light has come on. The codes say misfire in 3 and 5 cylinders and gearbox fault. I've changed all plugs and the coils that it said was misfiring. And still have same codes. Also I have changed the transmission fluid. After draining only one gallon I was able to get 2 gallons in it with no overflow at all. And still don't see the fluid. Shall I drain half the second gallon. It has no noticable problems other then when nailed down on the hammer it will stall out and loss all power to accelerate to where I have to turn off the moter and start it back up to regain power. Any help would be greatly appreciated
