What is likely to be wrong with my car if when in drive the car's rpm goes way up and it struggles to switch gears?

It could be a fault with the transmission control system
Does the D4 light blinks while driving?

No it doesn't blink. Just getting a lot of rpm and barely any acceleration. Then if I'm lucky it'll **** into gear leaving me screeching out.

That indicates the trans is slipping and if fluid level is correct, the trans could be on its way out.

I was afraid that might be the case.....so my last question would be is there a way to prolong it going out for 1-2 months so that diving would be possible?

Check the transmission fluid level first. If it is low, top up and retest.
Allow transmission fluids to warm up first and when trans is slipping, try not to stress it and avoid accelerating harder. That would cause the trans to slip more and cause faster wear of the clutches.
When problem occurs, try manually shifting between gears to see if it works correctly in each gear. When clutches fails, they would not fail all at once. Only control or fluid pressure would affect that.
One of the components that would cause intermittent non or erratic shifting would be the throttle position sensor and it might not throw any trouble codes. Get the TPS tested to ensure it is operating correctly.
Check for trouble codes by bridging the SCS connector under dash behind the glove box. Refer to the diagram.
As a final resort if others fails, there are transmisison additives available that might help to prolong the life of the trans or at least reduce the slipping until you can get it fixed. Check out with your parts stored for such additives.
