I own a 2003 Nissan Sentra s-er spec v. When I shift from 1st gear to 2nd gear at rpms of 2500 and higher, the shifter feels like it pops out of 1st gear. Also, when shifting into 3rd gear you can hear and feel a grind (with the clutch down). These 2 problems happen on occasion, especially on a cold start. However, I can actually make my car grind gears by holding the clutch down and moving the shifter in and out of 3rd gear.
