4l60E- No 4th or 1st gear or dash gauges *HELP*
I've got a 2000 Silverado 2wd. I started noticing this problem a while back, maybe a year or 2, but I parked the truck since I had my SS and never drove the truck. Since I've put a new engine and trans in the truck, the problem still persists. When I turn the key to the on position, the gauges come on and everything looks fine. When I turn the truck on the gauges will flicker on and then instantly turn off. I also don't have 1st or 4th gear(OD). I figure that it's in limp home mode because 1st and 4th are electronically controlled so 2nd and 3rd are the only gears I can manually get. I have pulled codes and it shows a 4th gear syncro and 1st(if I can remember right). It's been awhile since I had the codes checked but the codes weren't telling me anything I didn't already know. I was told that it could be the neutral safety switch but I'm not %100 set on that being the problem. The truck won't start if it's not in park or neutral but the lights usually work until I turn the truck on so I'm thinking it might be a short in the switch and it only stops working once the truck turns on. I'm at a loss, somebody please give me some advice
Thanks, Jordan

i had a 97 jimmy that did this to me... i took it to a shop and they said my tranny was bad... so i bought a brand spankin new one and they installed it for 1k total, then it happened again about 50 miles after the new trans install... i was told that it was then my abs sensor, i picked up one from the dealer for 100 bux, it still was happening, then i looked it up on the internet... and i found that it could be the ignition switch... replaced that and WOO HOO! workin trans for then next 20000 miles till i sold the truck. it was not giving the trans any power...
