I was unable to find anybody else with this same issue, so I started a new thread; sorry if it's a repeat.
Anyway, I just bought a 1995 k1500 chevy with I believe a 4l60e transmission. I know they have their issues, but I currently don't have a first gear, it always starts in second. Even when you shift all the way down to first, it won't go below second. The truck only has 104680 miles on it, and I'm wondering whether I need a complete rebuild, or if it's just an ECM issue possibly.

 

sounds like you lost a shift solinoid............but with that many miles I would just have it rebuilt cause starting in 2nd is VERY hard on it.

 

Yeah, I figured it might come to that... Well, thanks then.
Also, the guy who sold it also only put 4000 miles on it in the two years he owned it; I know he used it for towing, but I'm pretty sure it's within the last 1000 miles that it's been an issue.
