Hey there. The shop is called Superior Transmission, located off of the US54. If you are travelling east (away from the I10) exit Hercules, and stay on the gateway. It is slightly after the Hercules light to your right.
If I remember correctly, his name was Eddie. I’ll have to look at the business card again.
I am not sure about the pistons. The Transmission Guy didn’t say anything about those. The clutch packs in my 4L60E were the problem. I am sure if it were the piston, he would have told me.
None the less, all of the internals are brand new, and I got an updated Sun Shell, Clutch Packs and even a higher stall Converter, along with a rear main seal and full fluid change for the T-Case, Trans, and Rear Diff. So if the piston failed which caused the 3-4 Clutch pack to go (likely due to low fluid), it would have been replaced either way. My truck had this done at 196k and she now has 217k. She has been running great and I have even pulled several large hauls in the bed, and the transmission never falters. If anyone is in El Paso, TX, I can definitely recommend the shop I took her too.
Let us know if that solves the problem for you. I’d be interested to see if it is the piston like you mentioned. Thanks for your reply!
Just watched Part 7. Its on its way to completion. Thanks for sharing this series Eric. I love your videos and your how-tos, and have learned a great amount of mechanics from your videos alone.
Thank you for all you do!

So I got some video of my O2 Sensors on Live data. I thought id post here and show you all.
Its hard to say what is actually going on, because the O2 Sensors fluctuate alot from time to time. I know the Bank 1s are supposed to do this, but the Bank 2s are supposed to hover around .4 to .7.
Here it is at 2000 RPMs for 1 minute: [video]http://www.youtube.com/watch?v=Vx9Y0Zgz6uA&feature=youtu.be[/video] (http://www. (dot) youtube.com/watch?v=Vx9Y0Zgz6uA&feature=youtu.be)
And here it is for idle: [video]http://www.youtube.com/watch?v=sXEb2Y5x9oo&feature=youtu.be[/video] (http://www (dot) youtube.com/watch?v=sXEb2Y5x9oo&feature=youtu.be)
For some reason, the videos do not show up. Just copy the link in parenthesis and remove the (dot), and replace it with the correct character.

I just picked up an advanced OBDII Scanner from Harbor Freight Tools ($74.00, but came out to $60 +tax with their 20% off coupon. I even got a free screwdriver set!) that does give live data. I quickly plugged it into the truck and went to the live sensor data, and it was showing the #2 sensors on both sides fluctuating slowly between .4 to .7 volts.
Ill have to play with it more at the house, but I think this is saying that the Cats are bad on this truck.
I stil have to connect it to the Aveo as well.

I guess I would need to get a scantool that has live data. The problem is, those are very expensive, and I dont have $100 to throw away. I have a basic one however….
I will see what I can find as far as that. I wish I had a mechanic friend that had a tool like that, so he could get the live data for me.

No kidding! I have seen it drop drastically especially in the Aveo. The truck seemed to have the problem since I got it, but wasnt apparent till recently, so I was kinda used to it.
Anyways, you said that they cant be cleaned. What are my changes that changing the post-cat O2 Sensors would get rid of the code? I guess I should ask, how often does a P0420 code mean that the CAT is the problem?

Yes it was. Especially for the warranty.
They even cleaned up the case and looks like they slapped some paint on it!

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?
