The oil of any type (from Dexron III to Dexron VI) may be used for the 4Т40 transmission. The torque converter is a soft spot in almost all American automatic transmissions and requires replacement of spare parts quite early. Driving with worn torque converter may lead to vibrations, rapid ATF contamination and issues with the seal and bushing of the torque converter located immediately near the input. If this problem stays neglected, then it is required to change the torque converter bushing and the whole kit of bushings.The problem of burnt ATF is solved by replacement of all friction elements and the brake band.
