why does my toyota Corolla have no take off power in drive but fine in 1st or 2nd gear?

Question

I have a 93 Toyota Corolla automatic 1.8 that my dad let me have,he had told me that the transmission was recently worked on before he stoped driving it and the mechanic had to make some adjustments so the car would drive right but it was never done,so now im fixing it and dont really know what adjustments have to be done so the car can drive right.here are the symptoms

The transmission makes a taping sound when the car is on and  in park, when im driving it in (Drive) it has hardly any pick up untill it gets to about 40mph or the car is in 1st or 2st  gear  when the car is on 1st or 2st gear the car takes off normally. I removed the transmission pan and took off the transmission oil filter and  saw that the fillter was bent in a little but that was the only thing i saw and I did not remove  any thing else, can someone please tell me what to check or adjustment I have to make to get this car going? I changed spark plugs and cables,oil,gas pump and filter

The transmission problem isn't an adjustment. It's a failure to downshift. I can't remember if that old thing had a vacuum modulator, but I think it did. It can be as simple as a vacuum line from the intake manifold to the transmission coming off or leaking.

1993 Corolla had an electronic 4 speed automatic with lockup torque converter. Whoever worked on that tranny did a shoddy job if it was rebuilt. Otherwise, it sounds like a tranny going bad. I'd take it back to the m,echanice that worked on it if it's still under warranty. You need to look to your father for assistance on this one. He's the one who paid to get it worked on. He should find out (or know) what was done to it.
