LS/4L60E help
I need some help getting this going and I am at a loss.
I have a new motor after issues with the 1st one.The new one is a 6.0 iron block that runs great at least in 1st gear and idle I have had the PCM that came with the unit I bought and I have also recently had another PCM tuned by Garrett tuning in Ohio that was to help with shift points. I also took out the original harness and put in a new PSI harness. Still the same issues. Will shift in manual at least 1-3 but not in auto. What am I missing. The speedo is a GPS unit from what I understand that should not matter. https://youtu.be/jkvhadSxe2E Is it a tune is it a sensor????? |

Re: LS/4L60E help
Need to make sure the PCM is getting a VSS signal, Do you have access to a scanner or capable software?
Do you have anything tied onto the VSS sensor wire/s?........If so remove it & retest. |

Re: LS/4L60E help
Well I am going to do that and change the sensor. I assume I can check the wire with a test light or meter?
Next question is: The sensor I have was new in the box so I installed it in the tranny. Looking at parts websites many sensors look the same but different numbers. Assuming I got the wrong part number but it fits what is the difference in sensors? |
