I’m working on a 95 Chevy blazer and I posted something a little while back on how I couldn’t get the 4 wheel drive to work. This is strange to me because the person I bought this blazer from got a new tccm for it so I changed it out with the old one. Well it still does the same thing when you push 2 hi the 4 hi and 4 Lo blink a couple of times and neither light stays on. When you push 2 Lo both lights blink a couple of times and the 4 hi and 4 lo lights stay on and the 4×4 doesn’t work. Now this is what has me scratching my head. I accidentally forgot to plug the tccm back in after looking at it and every time I push 4 hi it will engage and work and when you push 4 lo it will engage and work however when you put it in 4 lo and drive with it in 4 lo it will drive in real lo and then when you pick up just a little speed and it shifts it shifts so hard It’s almost scary. It only seems to do this in 4 Lo and it will shift a little hard without the 4 wheel engaged but not even close as how hard it shifts in 4 Lo. Can someone please help me. Thanks again
