Can You Shift Directly from Fourth Gear to First Gear?

[DeZoe]

Shifting directly from fourth gear to first gear is not recommended, as it can easily lead to engine stalling, jerking, and damage to the transmission's mechanical structure. Gear shifting, short for "gear lever operation method," refers to the process of continuously changing the position of the gear lever based on road conditions and vehicle speed. Below is additional information: Oil Leakage: If oil is seeping from the transmission housing or oil pan, one possible cause is aging seals leading to poor sealing; another reason could be manufacturing defects causing pinholes in the housing. Engine Stalling When Engaging Gear: If the engine stalls when shifting into D or R, the issue might be due to a faulty lock-up solenoid valve or a stuck lock-up control valve. Locking: Incorrect input or output signals from the transmission, or issues with components or wiring, can cause this. Sometimes, communication problems between the transmission computer and other system computers may also be responsible. No Response When Engaging Gear: After shifting into D or R and releasing the brake, the vehicle does not move. This is often caused by damage to the input shaft or reverse clutch, or a faulty D/R brake.
