Get car seviced tops the list,
scan it if savvy.
you cant fix any A./T with out a scan tool !
the TCM brain will spit out errors that are KEY to accurate diagnosis.
buy a tool
rent one
get it scanned
barrow one
or get car serviced.
even a dirty VSS sensor can do that. TCM cant see road speed or
is reading wrong. clean it. it gets magnetic mud on end, clean off the mud, and try. it.
free fixes. can work. but... no scans NO JOY , mostly.
Run the fault codes to determine the fault are a first
next check the vacuum hose for the transmission actuator as that unit has a lot to do with shifting ratios

Try some Seafoam brand trans tune it might help.
Even if it dosen't it's a cheap experment.

your bands may need adjusting or the transmission needs to be serviced to find out if it is something more serious

Most Suzukis that are EFI do this. The vehicle speed is given to the ECM by pulses generated (in my case, a 1991, 1.3 GTi Swift) by the speedo unit. During gear changes, the throttle shuts and the engine would momentarily be starved of air and there would be a resultant increase in NOX emissions. The increase in air flow is from the ISC motor (idle speed compensator) and stops the mixture leaning out during gear changes. Don't mess with the TPS (throttle position sensor), and if you're changing gears at an RPM where the engine actually revs up, it's either cold, or you should be holding the gear a little bit longer. I'm in Australia.

Most Suzukis A/C systems will cut out when the engine tempurature is too high (to reduce the load on the engine). Also, in this condition, when the A/C compressor cuts out, the A/C thermo fan (electric - in front of the condensor) may come on ( to try and cool the engine). Combined with the fact that your temp gage says the engine is hot, I would be checking your cooling system very closely. It could be as simple as leaves blocking the air flow through the radiator (between the condensor and radiator), or as serious as the internal cores of the radiator being blocked (different sorts of coolant being used can sometimes produce solid matter that can do this).
Testimonial: "Great explanation and advice to check the cooling system, specifically the radiator. Unfortunately the internal core of the radiator was blocked."

Hmm couple of things.
Firstly if its going from drive and then sounds like its revving high and not doing anything then your torque converter is starting to go. Best way to tell if it is this put the car in N while parked up and take your foot off the brake if the car starts moving forward by its self then this is your fault!
Other thing it could be that your fluid level in the gear box is too low.
To be honest its nearly always the torque converter, this is the part that makes your car an auto. So as you will imagine its not cheap to repair. whats the miles on the car?
