94 B150 drops out of fourth
I have a 94 b150 5.2 4 speed auto, it's dropping out of fourth gear, the crusie control wont engage. I took it ti a friends shop we hooked up a scanner, we could see the solenoids operate but something is sending a signal to disengage, same as with the lockup torque converter. I replaced the differential speed sensor, replaced the overdrive switch which shows on the scanner its functioning preperly. The TPS also appears to be functioning properly. Could it be the computer?
