Changing E4OD Shift Speeds
I have a '90 E350 with 7.3L diesel. It used to shift fine, but the torque converter failed. I took it to the "best transmission shop" and had them repair with all the updates, a premium torque converter, and a high capacity oil pump. Since then the shift points are about twice fast as they used to be, for example, the 4-3 shift (coasting) occurs at about 38 mph instead of about 20 mph. All the shifts are at much higher speeds. The shift points might be OK for a gas engine, but are too high for the diesel.
I need to get it to shift at lower speeds as it did originally. One solution I thought of would be to hook something in the speed sensor circuit to fool the computer into thinking the speed is higher than actual. Any other ideas? Thanks.
