My discovery hates me! I'm having a hard time releasing the torque converter from my motor. I am trying to pull the engine to complete a upper/lower re-seal on a 1998 Land Rover Discovery LSE 4.0 (approx 150k miles). I think the Brits are trying to get back at the colonists for our little 'uprising'. PLEASE HELP ME!
