Pls stay away from that mechanic and never go back to him......as per my knowledge damage has been done to ur transmission and i am not sure how it will be corrected
.
3AT/4AT transmission is totally different from CVT transmission....please google it.....there is a reason fluids are diff for both transmissions....
.
The gears in AT needs diff fluid and the belts/pulleys in CVT need diff fluid
.
I hope someone here can advise on what need to be done in this case

Don't know well about these gears. Poured on mechanics recommendation.
