Question about 1988 Ford Bronco II
I have a 89 Bronco II and the engine will die as soon as i put it into drive. I recently had a diagnostic check done on it and it threw up a code 51 and 63. One of the codes is for a TPS. I changed the throttle positioning sensor, but did not help. It will go into reverse fine, but will die in drive. It has 130,000 miles on it.
When the vehicle is put into reverse. The transmission is working in 1st gear. The valve body and solenoids are working as designed.
When you change to Drive , The valve body could be getting stuck.
The transmission is starting our in a higher gear. Such as 3rd or over drive. There is to much torque for the engine to continue to run and is shutting down. Another possibility is the Torque converter has a lock up mode for when you are traveling down the highway.
This also can be stuck in that mode. I would take it to a local transmission shop for complete Diagnosis
