If it is a three speed transmission, there is an internal failure. If a four speed the computer has detected a malfunction and set a code.
check fuse inside fuse box trans axle fuse im not joking
Most likely the computer has detected a malfunction and set a code. Have the system checked for codes.
If its a older trans sometimes the vacuum hose comes off the trans solienoid.
If a transmission for a car becomes stuck between 1st and 2nd gear the fluid should be changed. Old fluid in a transmission can cause hard shifting and stuck gears.
This behavior is programmed into the transmission controller so that when its self-diagnostic capability has detected a fault that could cause damage it will only drive in 2nd gear which uses a minimum number of circuits. It is called "limp-in" mode. the best ting to do is to get a "readout of the transmission computer" (not th same plug as the engine computer) which is an electronic test for the presence of coded numbers representing different faults that the transmission is experiencing at the time when it locks up into 2nd gear.
If they cut a sensor wire, the trans could be stuck in 2nd.
If the vehicle is stuck in 2nd gear and does not change gears.... you more then likely have a bad speed sensor. The transmission is electronic and the 2nd gear is considered the " Safe" mode. Take it and have the transmission computer checked for codes.
Definition Stuck in 2nd or 3rd gear Probable cause 1. Open or short circuit condition in the gear selection switch circuit 2 Poor electrical connection 3 Failed gear selection switch
You need to have the system checked for codes. The computer that controls the trans has most likely detected a problem and set a code. That can cause the trans to be locked into second gear.
put a can of trans x one of the pumps are probably stuck follow the directions on the can
An automatic transmission stuck in 2nd gear and reverse can result from several issues, including low transmission fluid levels, which can affect hydraulic pressure, or a malfunctioning shift solenoid that controls gear selection. Additionally, a faulty transmission control module (TCM) or issues within the valve body can cause improper gear engagement. Mechanical problems, such as worn clutches or bands, may also contribute to this issue. It's advisable to have a professional technician diagnose the problem for accurate repairs.
To fix a John Deere RX75 mower stuck in 2nd gear, first, ensure the mower is turned off and safely positioned. Check the gear shift linkage for any disconnections or damage, and inspect the transmission for any obstructions. If necessary, adjust or lubricate the linkage and ensure the transmission is functioning properly. If the issue persists, consulting the owner's manual or a professional technician may be required for further diagnosis.
