P0165 is O2 Sensor Circuit Slow Response (Bank 2 Sensor 3).
Don't know what you mean by "TCM system reset has come up".

It means that it didn't receive a signal from the transmision module.
Have your transmission control module checked.
To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.

these do suffer from blocked EGR valves you need to remove it and take the solenoid off clean out all the soot.

unfortunately this means you need to get yourself to a trusted transmission repair facility very quick. the torque convertor on your vehicle is not operating the way it should. this is going to be an expensive repair, i tell you this so your not suprised. but do your homework and find someone with a great reputation for their work. dont take your saab to just anyone. these cars can get really screwed up without the right people workin on it. the transmission will need to come out.

The Code you're referring to should be a "P0502." What the Code signifies is: "Vehicle speed sensor circuit, low input."

You dont have to pull the tranny to fix this. Some so called "experts" on here shouldnt be giving advice if they dont know. The solenoid pack is located in the front the transmission just below the air filter and in front of the input speed sensor you just replaced. Unbolt the connector with a 10mm socket then the bolts connecting to the tranny. Replace with a new one 140 bux or close(get a new one). Installation is vice versa. Easy fix for any person who is mechanically inclined. Always get a second or third opinion when asking a thousand dollar question on any website. Some people think they know....but they dont.
Cluster
warning lights
Whenever this warning light or any
other stays on in the dash it is indicating that the systems control
module (or the system sensor in the case of lights like low oil
pressure, door open indicators etc.) has detected a fault, it then
disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL,
CEL and BCM faults and others) as long as the light is on. You must
now have the dealer hook up a special electronic diagnostic tool and
"scan" the system for the fault code that is stored for the
problem(s)
