I have an '02 GP GT that has thrown a P1887 code. Anybody here know anything about it?

Here is the first part of service info on the code. There is also a bulletin to check the trans pass through connector and terminals for poor contact or wires broken under the insulation

Thanks for the info. Took car to transmission shop last night after it threw code for 3rd time. They just called and the wiring harness has an area that is rubbed thru which is what's causing it to throw the code. I was expecting the worse.....which if you all knew the story of my last car you would know why, so it just being the wiring harness I'm good with.

That is actually a great diagnosis to receive.
