What happens when a catalytic converter overheats?
This excessive fuel in the converter results in overheating and melting of the substrate. A clogged fuel injector will result in a lean burn. Lean burn occurs when there’s too much air in the combustion chamber resulting in a misfire and excess hydrocarbon (fuel) entering and burning inside the catalytic converter.
What problems can a bad catalytic converter cause?
Among the bad symptoms of a compromised catalytic converter are: Sluggish engine performance, Reduced acceleration, Dark exhaust smoke, The smell of sulfur or rotten eggs from the exhaust, Excessive heat under the vehicle, Some of those symptoms can also be caused by other parts of the emissions system, so it’s …
Can a bad catalytic converter cause shifting problems?
A badly restricted catalytic converter will cause the drivers foot to be put nearly to the floor to get the vehicle to accelerate. On a new car or old, this will result in late, firm shifts. There is no actual problem with the transmission. But the driver thinks there is. YES, IT CAN.

What causes a Chevy transmission to not shift?
Low transmission fluid level. Chevy transmission won’t shift, stuck in 1st gear or limp mode – Speedometer may also display zero at all times. It could be internal transmission failure, low transmission fluid, or faulty Vehicle Speed Sensor (VSS sensor).
Can a defective solenoid cause a transmission to overheat?
A defective solenoid has to be replaced. A thorough diagnosis of your transmission overheating issues should be able to identify the solenoid as the problem, but sometimes the underlying circuitry can be the issue. Either way, the solenoid should be checked if all other issues have been addressed and your transmission still overheats.
