Is it stuck in one gear? If so, which gear?
If so, check the fuse for the tranmission.
Expert:  Mike S. replied 1 year ago.
Are you saying rather that the engine is in limp mode?
Are there any codes stored?
Failure of the MAF causes the PCM to trigger the "limp-in" mode.

It is stuck in 2 nd gear I think
Expert:  Mike S. replied 1 year ago.
I don't have live phone call setup.
Check the tranmission fuse.
Customer: replied 1 year ago.
I checked fuse and its good
Expert:  Mike S. replied 1 year ago.
It may be good, but you have to test it with a voltmeter or 12 volt test light on both sides to make sure, because what if something feeding it don't have power, then simply looking at the fuse isn't good enough. Understand? If you did actually test it, then move onto testing that wire at the tranmission.

I used a test light and it was good
Expert:  Mike S. replied 1 year ago.
So it showed voltage to both sides of the fuse? Ok then. Do you have voltage at the tranmsission?
Expert:  Mike S. replied 1 year ago.
You never did tell me what engine is this this.
I see that the trans fuse has a pink wire coming off it and splices into 2 pink wires which go to pins E and T of the tranmission. The key must be on run but I assume you already knew that.
