Dear,
You have a genuine problem, due to your physical need.
Which means there is no other way,
all the cons are subsequent to your physical need.
If driving is a problem, then sure convert it to automatic, but please find a very learned guy to do this for you,
and ensure proper workmanship.
That said, I would take that with a pinch of salt, as these mechanics are good for nothing most of the time.
The best way possible is to let people here, draw a sequence of steps that needs to be done,
and we can help you ensure that every step of the way is done right, so you never have a problem on the road.
regards.
