automatic transmission check — logbook Toyota Corolla 1993

after buying a car … after driving a bit around the city. I realized what was wrong., the overdrive mode light flashes on the scoreboard, plus the engine does not spin up above 2500 rpm.
having arrived home … after reading the Internet, I concluded. the box gives an error, signaling its problem.
making a couple of calls to friends. they sent me to the Novomatic service, where the guy, after inserting the diagnostic connector in 2 minutes, closing the contacts necessary for self-diagnosis, concluded ... 63 error, it was the solenoid in the automatic transmission that died (1 of 3), so what? make?
Yes!
pit machine. removed the pallet replaced ... screwed ... flooded ... removed the terminal, the error was reset ... and I went home happy)))

these are the first investments in a car
