RE: 2000 impala
With that new information I am still thinking that 3rd gear is probably OK. I am pretty sure that 3rd & Reverse go out together with a mechanical failure. Since you have Reverse, 3rd should be OK too. It sounds like the Torque Converter Clutch (TCC) is out and that would be the debris that you found in the pan & filter. It would be ground up and burnt clutch material. This stuff also travels through the valve body & plugs things up. It has likely plugged up the 2-3 Shift Solenoid and that is why you don't have 3rd gear. You could probably fix 3rd by pulling and cleaning the valve body. However, the Check Engine Light will remain on because you won't have lock up. For the amount of work involved in that I would probably just pull the whole thing, replace the Torque Converter & have the transmission rebuilt.

How long will it last? That is anybodies guess. With the debris in the valve body, skipping a gear & no TCC the odds are against you. When it does go & breaks things inside it will cost a lot more to fix.

You can read the code meanings here:

Code P0742: http://engine-codes.com/p0742_gmc.html

Code P0756: http://engine-codes.com/p0756.html

Thanks for the updates. Good luck. Please keep us posted with anything new.
