What is the reason why the Buick Excelle does not move when shifting to D or R gear?

It is usually caused by a damaged transmission control module. The damage to the control module may occasionally or completely prevent gear shifting. Of course, it could also be due to a communication failure between the vehicle's control system and the transmission control module. Below is an introduction to the Buick Excelle: 1. Body dimensions: The Buick Excelle is a compact car under the Buick brand. Its length, width, and height are 4609mm, 1798mm, and 1464mm respectively, with a wheelbase of 2640mm. 2. Powertrain: The 1.3-liter turbocharged engine of the Buick Excelle has a maximum power of 120kW and a maximum torque of 230Nm. This engine is equipped with a 48V mild hybrid system and multi-point fuel injection technology, using an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission.
I've been driving a Buick Excelle for over a decade and encountered similar issues. When the car doesn't move in D or R gear, it's often due to the parking brake not being fully released or getting stuck—check your parking brake first. If the parking brake is fine, it might be a transmission problem, like insufficient oil pressure, a faulty oil pump, or a blocked valve body, causing power transmission failure. My car once had this issue, took a while to fix, and cost me some unnecessary money. I recommend stopping immediately and avoiding forced starts to prevent engine damage. If you can't handle it yourself, call a professional technician right away. Regular transmission fluid changes can prevent this issue, as older Buick transmissions are prone to such problems. Safety first—don't risk driving it.
