Neighbor up the street has a 94 Suburban 4x2. Tranny was supposed to have been rebuilt 5 years ago. No problems until recently. Get in, put in drive, 1st is good, 2nd is good, most times 3rd will be like neutral. He states that sometimes it will go into 3rd like it is supposed to. I told him it is most likely the clutch pack gone, but he says sometimes it grabs fine. So I say maybe its a bad solenoid. We pull the pan, lots of "dust". I point this out and tell him its not bad, no chunks, no grit/grain, but lots of dust, so probably clutch pack. We pull the valve body, clean it up, looks good. Swap solenoids just for fun. Put it back together, fill it up, same problem. I suggest to bring the tranny to the local rebuilder and get it rebuilt. He wants me to do it, but I haven't rebuilt a tranny in years and would prefer not to mess with it. I will swap it out, but that's as far as I want to go with it. Is there anything else to check out, or should I just stick with my orig plan and just get it rebuilt by a rebuilder? I do have all the tools and equipment necessary, I just haven't rebuilt a tranny in quite a while.
