Need to no a few more details to help, the list of possibilities right now would be large. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.
Does it rev up freely in N or P or is it sluggish. I will post if any different when any changes. Otherwise, 2-4 band is worn out. Time is money, don't waste either guessing. Making me think that the part the the harness plugs into has failed.
Specialized tools are required to accurately diagnose trans problems! Is the check engine light on? In third gears you should still be less than 3,000 rpm. Ive changed the solenoids, fluid and filter and even added lucas antislip. This can really be the only thing it is seeing as it goes into 1 st gear just fine both of these are on the same fork.

Not a critical failure, but not a good sign either.
To repair this problem it would require the transmission to be taken out and disassembled in order to do the repair. Second gear is a default gear when the transmission is in limp mode. The transmission fuse is the ignition switch voltage for that circuit. The computer just checks code 12. Try not to run or drive the car or further damage could result.
So I tested both ways. Worn synchro rings can result in gear clash when going into forward gears though they can stick somewhat in new or recently rebuilt transmissions, leading to hard or noisy shifting, which gets better as the rings wear in. If you put it in low and lift the handle, it will go into second immediately and when you move to drive---nothing. After I got it back I got to thinking about it and disconnected it and my overdrive started working, so I replaced that part and had no more problems. The transmission will not shift either and you would have to change the fuel pump that's in the tank.

She took it to a shop where she said they cleaned a switch and reset the computer. Fluid leak out of the front of trans where the converter connects; partial or full loss of movement: Front pump bushing walked out. But with the wiring being different, who knows. We've worked hard over 11 years designing a website experience that makes it easy for anyone to idenify whether parts fit their car.
