I just did this on my 244 GL with an automatic transmission about a month
ago. I hope I remember. there is a chrome plastic piece on the left side
of the shift stick thing. you have to take that off, unscrew the plastic
cover that shows what gear you're in and lift that up. under that is a
brass colored piece holding the reverse lockout button in. you need to
pull that to the left, which will pull it out, then pry up the lockout
button on top of the knob. then pry out the overdrive button and
disconnect the wires. I think that you can just slide the knob off after
that. there is also a safety switch that lights up the plastic housing and
turns on your back up lights that might have to be taken off in order to
get to the brass piece but I don't think so. if you do, put the car in
park, lift up the housing, lift the safety thing up and disconnect the
wires. it should come out. I hope this is helpful
