I think I have a leak some where because the coolant lite keeps coming on but the coolant reserve tank is only a little low. This happens every one to two weeks. It's still missing a little after changing the plugs and wires which the old plug wires were melted on and a little difficult to get off. Ihaven't changed the trani fluid and filter yet that might help with the lurching and slow shift. I should probably invest in a code reader or some thing like that instead of stinking to the old fashioned way of probability and common sense.
