I did that (returned car to mechanic)they opend the transmission, tow reverse disks and their plates were burnt. The problem is they dont know what to do any more. This problem has been repeated consequently in this type of car. So I worry it happens again.

WHAT THE "Diamond ATF SP-III" IS?IF you mean hydraulic oil type, IT WAS MATCHED WITH IT. IT'S TYPE IS DEXTRON III WITH 'TRANSIT' BRAND. BUT I DONT THINK THERE IS PROBLEM IN OIL TYPE.
MY CAR TRANS IS ELECTRONICALLY CONTROLED TRANSMISSION
SOMEONE SUGGESTED ME 3 WAYS TO DO :
1-CLOSING OIL CURRENT IN RADATOR AND USING JUST TRANS COOLER TO COOL THE OIL.
2-THOUGHEN OR INSERTING SOME WASH AIR IN REGULATOR THAT IS IN PUMP.
3-OPEN TRANS CLOCK(I DONT KNOW THE EXACT NAME) AND RESETING IT.
