Has to do with the transmission. Can be wiring/plugs from the PCM to trans, wiring inside the trans, or a solenoids inside the trans is shorting out. Have the codes read. Check the trans fluid also. When it gets low, it can cause a pressure code. This will throw it into limp mode.
There are many different systems that could cause limp mode, engine, transmission, emissions... Limp mode is a safety that allows you to get off the street and to a shop for repairs without stranding you. Usually a significant failure eg trans will not shift.
Bypassing the neutral safety switch won't help with the transmission problem. That switch is only wired into the start circuit.
Scan the computer for trouble codes. Has to be a code if it is in limp-in mode.
Go to an Autozone, Advance, or O'reilys for a scan. Limp home means engine problems too.
Overheating is a problem or loss of signal from an engine sensor. One thing you might try is after, and only after you get a scan is to wipe the memory.
The companion computer may have embedded info and is responding to the old "Limp signal".
Check any Vacuum lines or Vacuum dashpots which can affect powertrain controls.
My 2 experiences with limp mode was on a 93' Chevy. 1 time was the ecm, but it didn't reset until I replaced the ecm. The other time was the main electrical plug that comes from the ecm. The largest electrical plug on the trans. I unplugged it and there was trans fluid inside the plug on the 16 pins that connect the external wire Barnes to the internal wire harness of the trans. This required a new harness inside of the trans and replacing the external harness near the trans. Not an easy fix and may not be your issue, but this issue would "come and go". Fluid would short out the communication at the pins.
P 1751 Shift Solenoid" A" performance. The solenoid is part of the transmission valve body and yes if this solenoid fails you will get limp mode.The only solution is a new solenoid may be even the wires to it or even the transmission module
limp mode as in computer limp in mode?check the trans fluid is it dark looking?,
Need more info. Did you have the trans fluid changed recently? The reason i ask is when you change the trans fluid way after its do the new trans fluid is detergent type and fresh fluid can put the transmission in shock(Trans Shock). This can wipe out a transmission in 5 miles or so seen it too many times.
Let me know how it goes. Lee
