Can catalytic converter affect transmission?
A clogged catalytic converter makes the engine work harder, which in turn makes it difficult to shift the transmission. In regards to air, a bad O2 sensor or dirty mass air flow sensor will also cause the gears to stick.
Is catalytic converter engine or transmission?
The catalytic converter has very very little to do with the transmission. The catalytic converter will keep the engine from being able to “exhale” and can cause engine problems and damage if faulty, but it wont cause direct transmission issues.
Can a catalytic converter just go bad?
Usually, a catalytic converter will last throughout the car’s lifetime, but sometimes it can go bad and will need replaced. Typically, this happens in older cars when the catalytic converter becomes clogged.
Can a clogged exhaust cause transmission problems?
Yet, there are many other reasons that cause trouble when shifting gears. For example, if the catalytic converter or exhaust is clogged, the engine may experience a back-pressure problem, making it difficult for the transmission to change gears.

Where are the catalytic converters located in a car?
Catalytic converters are part of the exhaust system. They’re located between the engine and the muffler, usually closer to the engine. This helps them warm quickly to the high temperatures where they’re most effective.
What does Italian tune-up do for catalytic converter?
If the engine control module (ECM) detects a catalytic converter problem, it might record DTC P0420, defined as “Catalyst System Efficiency Below Threshold.” The “Italian Tune-Up” is a common fix for a range of automotive problems, including a clogged catalytic converter.
Can a lazy oxygen sensor cause a catalytic converter problem?
You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself. A technician can determine if the sensor is responding as it should.
