We were towing our boat to the lake and our 1994 Suburban 2500 down shifted by itself from 4th to 3rd. It would not go back into 4th. At the boat ramp the vehicle was put into park and the RPM was approx. 2000. We decided to return home and the vehicle would not go into 4th gear. Also, the alternator gauge went into the red and the service engine
soon light came on. The directional signals also quit working. When we got the vehicle home it would not drop below 2000 RPM and when the engine was turned off, it will not start again. There is power to the windows and the air conditioner. Thoughts? Thank you!!
JA: How old is the transmission? Have you checked the brake switch?
Customer: The vehicle has 105,000 miles and the transmission is the original. What do you mean by brake switch?
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: We have been home less than 30 minutes but we are NOT mechanics so we have not tried anything but me googling and finding you. :)
JA: Anything else you think the mechanic should know?
Customer: The vehicle had 65,000 miles on it when we purchased it so you can see that it is only used for limited activities. Perhaps it has run it's course.........
