  • 4L60E TRANSMISSION HAS BEEN REBUILT. ORIGINALLY HAD NO DRIVE OR OVERDRIVE BUT DID RUN IN REVERSE, 2ND AND LOW. AFTER REBUILD IT CAN MANUALLY BE SHIFTED FROM 2ND TO 3RD THEN OVERDRIVE AND WILL ENGAGE ONLY AFTER 20 MPH. AT THIS TIME APPR 40 MPH FEELS AS THOUGH SLIPPING OCCURS BUT REMAINS IN OD UNTIL SPEED REDUCES AND IT LOSES D AND OD AGAIN.
