Several things can cause your transmission to be stuck in second gear. Broken or detached shifting linkage will cause the problem. A broken shifting for in the transmission can also cause the problem.
Because it is in "Safe" mode.
the tcm has a hard code stored and has gone into safe mode
The governor is stuck.
the transmission is stuck in a fail safe mode, indicating there could be an internal problem.
The automatic Toyota may be stuck in park because of transmission problems. The transmission may be jammed or stuck in that gear.
If it's in limp-in mode you need to take it to a transmission shop and have it diagnosed.
you could either have a bad syncranizer or the throw out bearing is up
The transmission computer defaults to second gear when it detects a malfunction and sets a code. You need to have the system checked with a scan tool to know possible causes.
If they cut a sensor wire, the trans could be stuck in 2nd.
You need to have the computer checked for codes. That will tell you what area the problem is in. It can be wiring, computer, or even an issue with the new transmission.
