2003 TOYOTA RAV4. WITH NO WARNING OR CHECK ENGINE LIGHT, CAR BEGAN BUCKING BETWEEN 1ST AND 2ND GEARS - BUT THEN SMOOTHED OUT IN THE HIGHER GEARS AND ALSO AS THE CAR WARMED UP. NO OTHER CARS AROUND SO NO DANGER TO MYSELF OR OTHERS. THOUGHT THE TRANSMISSION NEEDED FLUID, SO I TRIED THAT. SEEMED TO IMPROVE SOMEWHAT FOR TWO DAYS - THEN THE SLIPPING BECAME VERY BAD AND THE CHECK ENGINE LIGHT CAME ON. THAT SAME AFTERNOON I BROUGHT CAR INTO MY MECHANIC, WHOSE COMPUTER DIAGNOSED A DEFECTIVE SOLONOID. AFTER REPLACEMENT ($117), TRANSMISSION WAS STILL SLIPPING. FOUND A TRANSMISSION SHOP AND THEY DIAGNOSED A FAULTY ECM. COST FOR REPLACEMENT: $1450. DON'T KNOW AT THIS TIME WHETHER OR NOT TRANSMISSION HAS BEEN IRREPARABLY DAMAGED. COST TO REPLACE TRANSMISSION: $3500. *TR
