Question about 2005 Chrysler Pacifica

Can bad catalytic converter prevent a car from engaging gear ? It's 2000 model Lexus RX300,has a very loud annoying sound and had emission problem.Now the car wont move on any gear. It stations as if in neutral when you put on drive,does the same on reverse. I wanna know if it has to do with the transmission, or basically something else.

Hi Chike, An engine in a poor state of tune can cause problems with gearbox operation, but I have not heard of tuning causing complete failure of transmission. Your first course of action should be to check the transmission fluid level. If it's low, top up with the the engine running and check the ATF level in the usual way. If the box has leaked oil, have it repaired as it's causing damage to the environment and if neglected the problem will definitely reappear. If the problem persists have the car diagnosed by service technicians using diagnostic scanning equipment. Regards John

Sorry but if your reverse is having trouble you will probably have to replace or rebuild tranny like me. Otherwise try new filter and fluid first.

It could be caused by many things, but generally it means that your engine is running too lean - usually indicating a vacuum leak. It could also be that the O2 sensor is bad and giving a false reading.

Are you check trans fluid levels? Sound like a problem with the torque converter or internal valve body solenoids clugged. I suggest check with your technician before to buy or think in replacement parts.

Hope this helps.

Brake lights still aren't working on my 2000 Lexus RX300. Changed fuse, bulbs, and switch. What's next?

Make sure you have 12V when the switch is engaged first to ensure the electrical path is working, then the rest could be diagnosed systematically. Did the fuse burn so you could replace or you just replace for the sake of it? Did you measure the bulb continuity before tossing it away? Sometimes the oxidation on the bulb holder causes bad contact so light can't be on. Cheers
