Can a bad catalytic converter cause shifting problems?
Trouble Shifting Gears 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.
How does a Mercedes-Benz transmission adaptive shifting work?
It does this by monitoring different sensors such as the throttle or the gas pedal input and more. In other words, it learns your driving style. If you race your Mercedes-Benz, it will remember that and keep the gearbox in gear longer. If you drive it gently, it will adapt to that as well and change gears earlier.
What are the conditions for the converter clutch to apply?
For the converter clutch to apply, two conditions must be met: Internal transmission fluid pressure must be correct. The ECM must complete a ground circuit to energize the TCC solenoid that moves a check ball in the fluid line. This allows the converter clutch to apply when hydraulic pressure is correct.
What causes a GM torque converter to lock up?
Most of the time it is a stuck Torque Converter Clutch (TCC) solenoid, but this is not the only cause of this problem. General Motors has issued a few Technical Service Bulletins (TSBs) relating to this problem. There is also a specific diagnostic procedure to determine the exact cause of the TCC problem.
How can I tell if my GM converter is working?
If the upper switch with the vacuum hose is used, check the two wires at that switch. On the four wire lower switch, check the two wires farthest from the plunger. Check for 12 volts at both sides of the brake switch. Some GM vehicles have two electric switches on the brake pedal.
What happens if you remove catalytic converter on GMC Truck?
If your truck is a 1996+ and you remove the catalytic converter, since there is a pre cat and post cat sensor, the ECM/PCM sees no difference between the 2 sensors outputs and turns on the SES light. You will be fine so far as the ECM and OBD1 system.
Can a bad catalytic converter cause a check engine light?
Check Engine Light Comes On A bad or failing catalytic converter can also cause an illuminated Check Engine Light. The oxygen sensor and air-fuel ratio sensor in modern vehicles monitor the efficiency of the catalytic converter by tracking the gas levels in the exhaust.
Can a catalytic converter be removed from an OBD 1 truck?
SInce your OBD 1 truck only has a single O2 sensor that monitors the air/fuel ratio located before the catalytic converter, you wont have an issue if you remove teh catalytic converter.
How does a catalytic converter work in a car?
A catalytic converter is a car component that works to reduce vehicle emissions and pollution. It is a metal canister that is installed in the exhaust system. The oxygen and air fuel ratio sensors that modern vehicles are designed with monitor the efficiency of the catalytic converter by monitoring the gas levels in the exhaust.
