It is most likely the governor gear. The same thing happened on my 94 sentra. Cost to repair was $175 including new fluid and cleaned filter. Three shops said the trans was shot and wanted $2000 plus to repair. A little research and an honest or competent shop and it ran like new. Its been fine for two years. This gear is used on many models and often fails about 100,000 to 130,000 miles. It is accessible from ouside the trans it doesn't need to be pulled.
If you can feel the gear change from second to first when stopping you may need transmission fluids. The transmission could be slipping or going out also. Take the vehicle to a mechanic so that they can see what the problem is.
If a 1995 Nissan Sentra will not shift out of first, there could be a problem with the throttle valve cable. The transmission could also be damaged.
If it's slipping, it's most likely a slipping clutch problem. If it's an automatic, you're talking about a complete transmission rebuild. If it's a manual shift you're talking about a new clutch plate, pressure plate and throwout bearing and you'll need to have the flywheel resurfaced. The vibration could be several problems, but you had better take care of the slipping problem first, because once a transmission starts slipping, it doesn't last long. Clutch surfaces in an automatic aren't very thick and they don't last long once they start slipping.
I'd check the transmission fluid level first and then for a slipping band inside the transmission.
One thing that can cause this is a slipping automatic transmission. The clutches do not engage at first letting the engine run free, then they engage suddenly producing a slam or jerk. This will quickly destroy a transmission.

First you should Check out your Transmission oil level that could cause your car too jerk into gear. The only other thing it might be if the transmission is going bad and you should have it checked by a transmission specialist
