If your car is in need of a transmission repair, chances are it is showing signs to let you know. There are differences in “symptoms” depending on if your transmission is automatic or manual. In a vehicle with an automatic transmission, you may hear unusual noises or notice transmission fluid leaking. The check engine light will also most likely go on, or the vehicle might not even move at all. In a vehicle with a manual transmission, you may experience difficulty shifting gears, or the gear popping out. There also may be unusual noises when shifting gears or you may find the clutch slipping.
