limp in mode 4l60e wiring harness help

[C1500stepside]

Ok so my trans has been stuck in limp in mode for the few months and I have changed both shift solenoids with negative results. So last week I took to one of the mechanics here at the shop I work and he said I needed a new tcc solenoid and wiring harness (they come together). So I came across this harness on amazon and i was just wondering if anyone has used it before? Because for the $40 its a real deal. The dealership is charging $177 for it! And ac delco has one for $108 on amazon. Well heres the link to the harness im talking about. Thanks for any and all help and suggestions. http://www.amazon.com/gp/aw/d/B009G...n-shift-solenoid-tests-2&tag=easyautodiagn-20

They usually are around $35-45 dollars. I wouldn't pay more than $45.

Whoa sweet. These are OEM replacement? What kind of warranty and/or guarantee so these have?
