The output shaft sensor is where the TCM gets its info. And what the speedometer runs off of. It is best to have a diagnostic ran on this first. But shooting from the hip, I would go for the output sensor.
Testimonial: "so far so good thanks "
The cruise control is controlled by the ECM. Which is getting info from the speed sensor also, The ECM also sends this info to your speedometer. With this being so erratic, The ECM wont set the cruise. Even when it settles after 20 minutes, there is still a fault. Most likely when the speedometer issue is fixed and all codes reset the cruise should start working again
about how long should this take? Did a brain kill and all service lights off but cruise still doesn't work.

ok changed both sensors so far so good but the cruise control won't work and since i drove the van before i changed the sensor and the "problem" "fixes" after 20-30 min and stays fixed till next day i'll let you know about the sensors. any ideas about the cruise, it worked till this "problem" started,
ok no problem after i changed the sensors as far as shifting but cruise still not working. did a "Brain Kill" to reset faults but only thing working on cruise is the light???
