A seized up transmission can cause a Volkswagen Golf with an automatic transmission to not shift and racing RMPs after second. A worn gear can also prevent shifting.
There are several causes that an automatic transmission will not want to shift into second gear. The two most common causes are transmission pump issues and trouble with the vacuum modulator.
An automatic transmission might be slow shifting from first to second because of low transmission fluid. You might also have damaged the gears in the transmission at the area between first and second.
A bad transmission gear can cause your 1999 Nissan frontier to shift hard. Low transmission fluid can also cause the transmission to shift hard.
Check the transmission fluid on the 1995 Nissan Altima. Bad fluid can cause the transmission to shift harder on parts that are more worn.
More likely it has something to do with pressure problems in your transmission, check the fluid and replace the transmission filter. If the problem is not fixed check the vaccum lines running to the transmission and the vaccum off the engine.
If the transmission computer detects a malfunction it defaults to second gear. It will have codes stored. Other causes include low fluid,and internal failure.
That would be the second gear of your automatic transmission.
Do a VIN search and the VIN will tell you the original options.

A car with an automatic transmission shifts itself from 1st to 2nd to 3rd when you accelerate. You don't need to shift it...that's why they call it automatic.
Typically, just age. Each gear of an automatic transmission is operated by one of a set of clutches or bands. When a band or clutch wears out that gear is through and the transmission will need to be rebuilt. The Valve Body controls pressures to different pistons in the transmission. At specific events the valve body causes pressure to be applied to the 2nd gear clutch piston and if the pressure is not sufficient the clutch may "slip", causing additional and premature wear. Driving a vehicle with insufficient ATF can also cause slipping and wear.
