Where is TCM located?


It is actually infused in the Body Control Module. (BCM) You'll need to replace the BCM (Nice work there GM) Some bypass systems have been known to work as well.

My 2004 Saturn ion 3 has 2 codes coming up u2105 p0700 an it won't go in drive or reverse what could it be


First off you need to understand your vehicle has several control modules on board . The PCM - engine computer , TCM - transmission control module , SRS - air bag module , Anti theft , antilock brakes , An these modules all are able to talk to each other on a communication network , On your vehicle it happens to be the CAN data bus !
The transmission control module (TCM) uses the controller area network (CAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure that affects emissions has occurred in the transmission control system. When the ECM receives the correct message from the TCM, DTC P0700 will set.
Which transmission does your vehicle have ?
Automatic Transaxle AF23-5
OR
Automatic Transmission VT25-E
DTC U2105-U2199
The controller area network (CAN) serial data line is a high speed serial data bus used to communicate information between the engine control module (ECM), body control module (BCM), and the transmission control module (TCM). Typical data-transmission speeds must be high enough to ensure the required real-time response is maintained. The CAN serial data line does not communicate with the scan tool via the data link connector (DLC). CAN serial data information is interpreted by the BCM and transmitted to the serial data line by the BCM.
I suggest you take this to GM dealer or some other ASE certified repair shop .

Sorry to tell you this, but neither of those computers would require any work on the HVAC case. The BCM is located above the instrument cluster. The TCM is located under the hood [which is a very poor location] I'm a 35 year professional mechanic. Sorry to tell you this, but my opinion of the Altima is very poor. These things have all sorts of problems, are hard to work on and the parts are very expensive. Lots of recalls and TSBs [technical service bulletins] TSB is dealer speak for "oops, we goofed". You can't blame the dealer for this one.

Engine light on & dashboard light says trans fluid


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 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)
