guessing, i see.
no year car stated
no engine option, which engine.?

why not get it serviced?
why not use a scan tool (1996+) and see if there are stored or live
DTC errors. (tops list)
A/T issues.?
a technician can tell you if the engine lacks power or the trans is failing.
The transmission will never use OD if the engine lacks power.
or the transmission or engine are stuck on limphome mode.
The TPS most be calibrated, ever seen the FSM book
the factory service manual> if set wrong idle speeds will wrong.
that which is stripped is bad, replace object stripped, the TB.?
the "Throttle body" or re-tap it or heli-coil it.
Test 1: done i 3 seconds flat
see FSM , see Trans, chapter.
see the stall tests. does that pass, parked, hot engine.?
that be first. if not , we work that first.
stall rpm too low, bad engine.
stall rpm too high , bad tranny.
i never once said to replace a part, that be last. (after diagnosis)
tell more get more.
