Car Forum / Ford / Ford Trucks / May 20051990 E-150 E4OD Question
As the subject line says, I have a 1990 E-150 van with the towing package, a 351FI, and an E4OD transmission. By what means are the shift points determined? Does this transmission use a VSS on the speedometer output? The van today was staying in 1st gear too long before shifting, requiring me to shift it to 2 manually. Also the ABS light is on for the rear ABS system. I had assumed that the sensor for that was on the rear axle, but could the two problems be related? Thanks, CJB Oh, I should mention that I think the Neutral Switch, or whatever that thing is called now, is bad because it leaves the backup lights burning. I recently had to take them out and haven't replaced the switch yet. If that's not what sets the backup lights, I'm interested in how to fix that too.

After looking at the van today, there indeed is a VSS at the Speedometer Cable output at the Transmission, and another one on the differential. Hmmm...

Since the shift issue only occurred one day and went away on its own, I can't tell a difference. I 'm sure that took care of it though. As I mentioned before, I also have a ABS light on that I'd hoped would go away if I replaced the VSS. When the front VSS didn't make a change in the light, I also replaced the one in the differential. Unfortunately, the light is still on... Any suggestions about the VSS?
