For a few years, at least in my area, there was a issue with the tcc solenoid. It involved not only replacing the solenoid( dropping the pan and unbolting from the valve body) but also flashing or updating the control module.once both repairs are complete you should have no problems. A good dealer will help you out.

I had the same code on my 2001 dodge 2500. The truck wouldn't shift from 3-4. I pulled the trans pan off and replaced a broken spring ($2.00). It is behind a thin plate with 3-4 small torq screws. You don't have to remove the valvebody. Only took me 45 minutes to fix.
I would like to give thanks to Jeff Russel from Teal automotive. He said this is a very common problem. He sells any part for any automatic Transmision and his prices are very affordable.
Here is a link to the website.
Hope this helps.

This code means that system to lean, bank 1.
some of the possible causes to make this code set are
1. intake or exhaust leak,
2. problem with the air system.
3. MAF (Mass Air Flow sensor)VAF sensor (Volume air flow sensor)
4. fuel pressure/pump
6. HO2S (Oxygen sensor)

I have never seen P0000 but P1740 is a standard autotrans code it should have another code with it,P1740 just tells you that the fault is in the automatic transmission.

That code is the EGR. I'd start by checking for a bad connection on the EGR plug-in. Pull the connector off and inspect each individual terminal inside the plug and the connector pins inside the EGR valve.
I found this solution at another forum on this issue. It worked on my 2001 Grand Am:
"Many GM built cars have a tendency to have the 'Check Engine Soon' light come on as a result of DTC code P1404. P1404 is described as EGR valve pintle stuck open, which in most cases is a false alarm. I had this happen with my '01 Grand Am. A little bit surfing on internet reveals that GM has a solution for the problem, a re-flash for the car's computer.
A software re-flash as a fix kind of indicates that the vehicles with this problem were built with it but I don't think GM will be re-flashing cars outside warranty for free. They will want their $100 for it.
Some hands on people I found had purchased a new EGR valve and changed it but the problem remained.
Possible reason (very likely) for the false P1404 code is that the plastic piston of the EGR valve position instrument (LVDT?) wears over time and starts reading a different position at valve closed than what it was when the EGR valve was first installed.
When the car was built and the computer circuits energized for the first time the computer learned the EGR valve closed position signal from the valve position instrument that is built on top of the valve itself. Over time, when the instrument wears, a slightly different signal is sent to the computer and when it differs enough from the 'Valve Closed Signal', that the computer had learned, the trouble code P1404 is set and the 'Service Engine Soon' light comes on.
Replacing the EGR valve with a new one does not necessarily fix this problem because the 'Valve Closed Signal' between valves is slightly different and it is just pure luck if your new valve would give a 'Valve Closed Signal' close enough to your original valve's signal not to set the trouble code. This is why the new EGR valve 'Valve Closed Signal' must be re-learned by the computer.
So, what this all means is that if the P1404 is a false code meaning that the valve pintle is not stuck open, then new 'Valve Closed Signal' can be re-learned by the computer using the old valve.
For fixing this problem the tool you need to have is a simple OBD II code scanner that can be used to erase trouble codes. There are many scanners of different price range on the market. I purchased one from AutoZone for about $90.
A code scanner is a very handy tool to have and I recommend everybody who is just slightly hands on type of a person to get one. It will end up saving a lot of money over time.
The fix goes like this:
1. Disconnect the wire harness from the EGR valve.
2. Turn key ON and erase the trouble code(s) from the car's computer AND TURN KEY OFF IMMEDIATELY WHEN THE SCANNER SAYS CODES HAVE BEEN ERASED. DO NOT TURN KEY ON BEFORE YOU RE-CONNECT EGR WIRE HARNESS.
3. Re-connect EGR wire harness and your problem should be fixed.
I learned this fix from OBDII.COM where carfixer and kozloski discussed it and I think kozloski was the one who provided the solution, so thanks to them.
There was also other people stating that this fix really works. Now I have joined this group of people as I got mine fixed using this trick also.
I believe erasing codes with wire harness disconnected and turning the key OFF right after P1404 code has been erased re-sets the 'Valve Close Position' reading in the computer and triggers computer to re-learn position next time the key is turned ON.
If you don't have an OBD II scanner and don't want to buy one some car part stores may erase the code for free, but if you have it done there you must tell them about turning the key OFF at the right moment. Other wise the re-learn process does not take place.
