It could be the source of hard shifts. In an electronically controlled transmission many sensor inputs determine shift times and firmness. If the back pressure of the exhaust is reintroduced through the exhaust gas recovery (EGR) valve to the intake then the power control module (the car's "computer") may interpret this as heavy engine load and raise the transmission line pressure to protect the transmission from slipping. This will be felt as hard shifts.

Would a clogged catalytic converter foul out spark plugs?
Yes, a clogged catalytic converter can lead to fouled spark plugs. When the converter is obstructed, it can cause increased exhaust backpressure, leading to incomplete combustion and unburned fuel entering the exhaust system. This excess fuel can then accumulate on the spark plugs, resulting in fouling, which can affect engine performance and efficiency.

Will a bad catalytic converter burn gas?
Yes, a faulty catalytic converter can cause fuel consumption to raise. Replacing a known bad catalytic converter will help, but keep in mind, the catalytic converter usually does not fail on its own. converters are pretty tough, living their lives running at 2000+ degrese internally. I would check your EGR valve and EGR valve tube for blockage or carbon build up. a faulty or clogged EGR valve will overtime distroy a catalytic converter. second thing to check is your Oxygen Sensors. these sensors are the computers first reading of bad fuel mixture, if they are clogged with carbon, they can distroy your EGR valve, which inturn kills your converter.
