Have a Code P1811 on my 2002 Pontiac Grand Prix. The only thing I have noticed is it gets warm very fast. Haven't noticed any slippage with the tranny...What do I do??

SOURCE: 2002 pontiac bonneville transmission jerks

Had the same exact type of problem. Sometimes the transmission would **** or jump when the car shifted gears and sometimes it would not. Drained the transmission fluid and replaced the filter. Did not fix the problem.

Here is what fixed my problem. I replaced the Mass Air Flow Sensor. It cost about $150.00. From what I was able to find out the mass air flow sensor is tied into the PCM module that tells the car when to shift.

Hope this if helpful.

How do I stop the grinding when starting 2000 Astro Van


Hello Anonymous...

To inspect the teeth on the ring gear requires the inspection to check the full 360 degrees of the ring gear. Looking past the inspection cover to examine a small portion of the ring gear may reveal no issues, but only for that section. Eventually the ring gear will end up positioned above the starter drive gear which will skip across the bad teeth creating your grinding noise when you try and start the Astro,.
