1990 Mazda 626 Transmission and drivetrain Problems

“I bought a 1990 Mazda 626 about a year ago. It has an atx. Recently the car would only drive in one gear. I took it to a buddy of mine that owns a transmission shop. He ran a diagnostic and said the car needed a new vehicle speed sensor and probably a new transmission. I purchased a new speed sensor that goes behind the speedometer, and now the hold button flashes. According to some research I've done this means that I need a new tranny. I can't get the car into reverse or into neutral. And the car will only go in third gear.”

“Power door locks no longer function from the main drivers door lock, tape deck died with at tape inside, rear drivers side passenger door latch cannot be opened from the outside using the handle-must be opened from the inside, backup light/license plate lights will not work regardless of bulbs..wiring is dead, transmission slipped from drive several times while driving on highway into neutral, just died entirely after being parked. Transmission will no longer engage..not a fluid issue. Also have had multiple thermostat failures in the winter resulting in no heat. …”
