Toyota Repair: 2002 Toyota Corolla s, toyota corolla, metal particles

Question
I have a 2002 Toyota Corolla S 1.8. Check engine light is on and the
code is P0770 shift solenoid e. Had the Mechanics look at it and had the torque converter changed,O2 sensors and shift solenoid changed 2 times,and the cat changed 3 times. and a computer was changed and the light keeps coming on. Just so you know i had to replace the engine.

Answer
It's a transmission problem, even if the torque converter was the ptoblem what happens is that when the converter fails the metal particles from the converter are still in the transmission fluid, you can try having the transmission fluid flushed but I think the transmission is on it's way out.
