Hi to all I would like to know if it is possible to disable the input speed sensor on a 4L80E to stop it going into limp mode. I am using a P01 0411 PCM. The trans mission will go into 4 once and then go into limp mode.
Please can you help me.

Do you have the front speed sensor installed?
No I am trying to run it without the sensor as it is a stand alone on a old school 350 chey motor. with a 4x reluctor and a tps. Would I need to install the sensor. Is there no way of switching it off.
ive never seen that done, its not hard to install the sensor.
Might make life easier for you to have it in there and feed the PCM with info it needs.
Thanks I have solved the problem. My own stupidity. All working as a stand alone transmission controller.

I am not using the input speed sensor only the output sensor. I plugged it into a 4l80e I have lying on the floor and used the simulator for the TPS , Speed and RPM and it is now shifting and converter is locking up.
RDF1 You could has left you previous comment on and not changed it I have Broad shoulders and a thick skin I was not offended in any way. We learn as we go. Thanks
