Thanks, mine is 23 and 15 so I'm thinking a 6 will put me with in the limit by one inch. About the transmission, I have an automatic and the owners manual says to turn on the ignition, take the parking brake off, turn the key to on, put it in neutral and when it shows in neutral turn the key off and disconnect the battery. You can't take the key out until the battery is disconnected. The shop that installed mine was going to put a battery disconnect on it, but this car for some reason states do not install one.
