BMW 525i transmission stuck in 3rd gear with hard shake when shifting from park to drive or reverse on BMW 525i

Some BMW 525i owners report experiencing issues with their transmission being stuck in 3rd gear and a hard shake when shifting from park to drive or reverse. These problems may stem from low transmission fluid levels, which can lead to inadequate lubrication and improper gear engagement. Additionally, a faulty interlock switch may prevent smooth shifting by failing to signal the brake lights, complicating transitions from Park to other gears. Owners also report that transmission seal issues can cause jerking movements during shifts, as leaking seals may lead to a loss of fluid. Furthermore, worn clutch plates can contribute to difficulties in achieving smooth gear changes. To address these concerns, it is recommended that owners check their transmission fluid levels, inspect the interlock switch, examine the transmission seals for leaks, and consider having the clutch plates assessed for wear. Taking these steps can help resolve the transmission issues and improve overall performance.
