I dont mean to steal this thread, but I just had a question along the lines of O2 sensors.
I have a 98 Silverado 1500 and a 04 Aveo LS, both with P0420 codes.
The Silverado has 196,200 miles now, and the Aveo has 142,000. I was wondering if a dirty O2 Sensor could cause the code to show up. The Aveo has it come and go, while the Silverado is on constantly and has it as a Pending Code.
I was wondering if a dirty sensor would do this, because of the fact that it comes and goes on the Aveo. I was told to take out the post-cat O2 Sensors and take some sandpaper to the tip to clean it up and then reinstall. Has anyone done this to fix the code?
And a little money spent is what helped here. I found a good reputable Transmission shop here and took it to them. The guy was really cool and very fair. I got the truck back about 3 days ago and it is running great.
According to him, it was the 3/4 clutches that were the problem. He went ahead and rebuilt the entire thing and even upgraded some things like the Sun Shell and others. I went ahead and had him do the fluids in the Rear/Front Diffs, the Transfer Case and the Rear Main Seal on the engine. $1675 is how much I spent and got a three year warranty.
Wrench Turner: I tried not to drive it, but when I had to (plus when I had to drive it to the Trans Shop), I had it in second per the website.
Skippy: I have 196,000 miles on it. It arrived at the trans shop with 196,035 Miles.
Hellraiser: I had not seen anything leaking at the transmission or at the front of the truck, so I believe the lines are good. 3 days after the rebuild, it has been doing great with no leaks.
Dreamer: No CEL Codes…the only one a P0420 and P0430 code. Those are catalyst codes though, so nothing related. I had considered replacing the filter and fluid, but I had spoken with other shops and specialists (and your everyday home mechanic) and while it MAY fix it, its not guarenteed. I finally decided that with the amount of miles on it and the possibility that it was abused up to 186,000 miles (when I bought it), It would be best to do a rebuild.
Thanks to everyone’s suggestions and tips. I really appreciate it. +1 to all for the assistance!
