Auto transmission not shifting up
Hi:
I have Maxima '96, ~243k miles, auto transmission. For the last week, transmission behaved funny but I could not clearly sense what was exactly wrong. Yesterday, it stopped shifting up:
o press the gas pedal, car starts moving;
o shifts 1st, 2nd, then don't shifts;
o pressing gas pedal just increases RPM;
o rear shift works;
o I had to put it into D2, then it does not even try and allows me to drive with ~40MPh and ~3000RPM.
What could be possible remedies to try beyond something major (like replacing this AT with used one)? I am not a mechanic, cannot do it myself, major expensive job (more than $300-400) is not an option, but I would like to know if I can ask my mechanic to check some smaller stuff first.
Thanks!

Most automatic transmission shops will do a quick but limited check for free. Based on that, they may need to do more extensive diagnostics that they would charge for.
Good luck on the $300-$400. Automatic transmissions are expensive to repair. Even buying a used transmission for that small of an amount is doubtful and then you have the installation charges.

>engine won't rev above 3000 rpm?
No, it goes above OK. I am putting it in D2, then I can accelerate to ~40MPh, and it shows ~3000RPM while doing that. Pushing gas pedal adds RPMs, but not much speed.
If I put it in D, then it revs up to 4000-5000 when I push gas pedal, but speed stays at ~20-30MPh because it is not shifting up.
I checked the AT fluid level - looks OK to me, color is also good.
