The Truck 06 2500 Silverado cclb WT
The Story,
Well about a 2 weeks ago we had one of our tow trucks go into limp mod after making deliveries all day
Friend of mine is the company mechanic along with myself when things go wrong.
He hooked up the computer and got a p0877 code which read "Transmission Fluid Pressure Sensor/Switch “D” Circuit Low"
We have had this happen once before on a different rig and replaced the PSM and go about our merry business, unfortunately that was not the case this time.
So he got called out to a job and I was called into the ring :hug:
First thing I do is grab my atsg and start testing For resistance... well everything tested good and I was stumped!
So I called up the Master Allison mechanic and asked him what he thought
And he told me he never heard of a p0877 so I said crap lol!
I told him what it read and he said I had a short somewhere in the wire.
At which point I realized DUH it said "circuit low"
So then came the tracing, after searching harder than a liberal for dirt on Trump I found nothing.
I then went to my old friend who started this project and he said well it is a GM and they are notorious for bad connectors so we tightened them up with a pick at the PSM and put dielectric grease on the plug going into the trans and BOOM
Problem solved
Been towing great for a week now!
BIG Thanks to Mike L. For helping me see the forest instead of focusing on a tree!
Hope this helps someone in the future :thumb:
