I have a 2007 LQ4 with a 1997 4L60e combo. Everything works perfect except for my neutral safety switch. When I say everything works perfect, I have driven it over 1000 miles with no issues at all. It will start in any gear and I need to fix this. I have a B&M megashifter with the switch mounted on the side. One side of the switch is grounded. The other side has wire#34 from the C1 blue connecter out of the PCM ran to it. I have P0850 in the DTC's turned on. DTC P0705 is turned off as my tranny doesn't have the switch mounted on the side of the transmission. I have tested the switch and the contacts work as it should.
Any advice would be appreciated!!
