Why doesn't the Buick 1.5t move when in gear?
2 Answers
The Buick 1.5t doesn't move when in gear because there is an issue with the gear synchronizer in the transmission. P gear is the parking gear: At this time, the car will stop in place even without stepping on the brake, and it is generally used when the car is parked for a long time. R gear is the reverse gear: When the control lever is in the R gear position, the rotation direction of the transmission output shaft is opposite to that of the engine, allowing the car to reverse. N gear is the neutral gear: When the control lever is in the N gear position, the gears inside the transmission are in an idle state, the clutch is not engaged, and the load on the transmission is minimal at this time. D gear is the driving gear: When the control lever is in the D gear position, the gears inside the transmission automatically switch between the lowest and highest gears according to factors such as vehicle speed and throttle opening, following the set shifting pattern.
I've seen this issue way too often. The Buick Regal 1.5T not moving after shifting is usually related to transmission problems, such as dual-clutch system stuttering or torque converter failure causing power transmission loss. It could also be due to faulty signals from the electronic control module, or a broken gear position sensor making the car 'pretend to sleep'. My advice is to first try restarting and shifting again to check if the engine responds normally, then inspect whether the transmission fluid is insufficient - changing dirty fluid can solve many issues. When driving normally, avoid stomping on the accelerator to reduce transmission wear. If this really happens, pull over immediately - safety first - and get it checked at a specialized repair shop right away.
