This problem sounds like it could be the torque converter. Everything in the Automatic tranny relies on pressure and the Torque converter provides this pressure with the fins inside of it spinning and pushing the fluid to each valve and port, acting as a Pump (the only pump for the Tranny fluid). If the fins wear out, break or get weak, it could cause a "Slipping" effect. It would have a harder time on hills, less power and need to spin faster to create the same pressures to finally shift and in some cases, never get enough pressure to get into top gears such as OverDrive. As for not going into Reverse or Drive unless going to Neutral, Again this can let the Tranny build more pressure sitting in Neutral to shift to drive or Reverse. This problem is usually found on vehicles that have done a lot of Pulling (trailers, campers) or heavy acceleration (Going up hills, first off the line at the stoplight) and/or do not get scheduled Tranny flush and filters. This May or May Not be the answer, but might be one more thing to check. I hope it helps.

Thanks for the info., I'm really beginning to think I'm never going to get my blazer back. The mechanic is still working on it. He let it slip yesterday evening that he was taking parts from a 02 Tahoe and mixing and matching with my transmission. I've suspected all along that he's been using salavage yard parts but now I know for sure. He told me yesterday that he got a GMC transmission (from another salavage yard) and it would be fixed today. I'm just so frustrated. I haven't had my vehicle for almost 2 weeks again. When we took it to him we told him we didn't want salavage parts, but evidently he's been using them anyway.
If its not fixed this time, I'm going to give up and get a Jasper transmission. I don't know what else to do, I'm getting desperate.

I have a 2000 Blazer with a 4.3 4wd.It revs up to almost 3000 rpm's before it will shift into 2nd gear.Third and fourth seem ok,but it doesnt seem to shift into those gears properly either and it also has no reverse.The 4wd works fine.If any of the sensors were bad,wouldn't the service engine light come on?I have no dash lights on.I'm going to try resetting the computer and checking the fuses.I see i have kinda the same upshifting problem as a lot of the other folks here have but no one mentions not having reverse.Any help would be greatly appreciated.
#115 of 382 Noisey 91 chev 5 spd trans.
Dec 14, 2007 (9:28 am)
I own a 91 chev silverado (350ci., 5 spd. man trans). I recently had the trans rebuilt at a trans repair shop and when I got the truck back the trans is still making noise in 3 of the 5 gears. I took it back to the shop and the man tells me that this trans in particular makes noise from the factory. now my warranty is nearing expiration , I would like some advice from anyone who can help me with this. Is this man telling me the truth or is he being dishonest. Any advice would be greatly appreciated

I have the identical set of symptoms on my 1997 4.3 4WD Jimmy. The problems just started on the weekend - no fix yet.
#117 of 382 97 Jimmy wont go in reverse.
Dec 20, 2007 (9:27 am)
Looking for a quick fix instead of dumping another 1,000.00 in it. My Jimmy had a rebuilt just over 2 and1/2 years ago. Only put 20,000 on it since and out of the blue reverse just went with no signs of any issues. All other gears and 4wd work fine. Checked fuses and Im gonna drop the pan and check for a blocked screen and any chunks of metal in the pan also. Anyone have any other ideas for a fix please help me. lol thanks all.
#118 of 382 front differential problem?
Dec 22, 2007 (8:51 pm)
I have a 1999 Chevy Blazer 4x4. In 2 wheel drive, when going on the expressway, it starts to make a noise like a "router" (high pitch grinding, that varies with speed) As I slow down, the noise lowers in pitch and I can feel a vibration that seems to be located in front of the passenger side. The noise stops after a slight "click" when I finally get down to about 3 miles per hour. It doesn't start again until I am doing at least 50 mph. There is no noise in 4 wheel drive. I am also having a vacuum problem because the vents don't work as well as they used to. I found a short (about 8 in. long) rubber vacuum line that was not connected to anything that was tucked under the ABS manifold, but I couldn't find where it came from. (I had a new engine put in in June) could this be a simple vacuum problem? Is there a vacuum connection to the transfer case, that is, the 2 to 4 wheel drive actuator? Any idea where that short rubber hose goes to?
#119 of 382 2000 Blazer tranny problem
Jan 06, 2008 (5:56 pm)
My check engine light recently came on and i had it put on machine. It said it was my shift solenoid A in my transmission. Do you know what this is? My blazer seems to shift back and forth on its own and my tac. says about 2000 rpm when usually reads about 1500 when traveling about 50 mph. The mechanic said i need to take it to a transmission person. I got scared..This could be expensive. My question is what is a Solenoid A and is it difficult to fix?
Any help would be greatly appreciated..
#120 of 382 1993 S10 Blazer transmission problem
Jan 15, 2008 (1:10 am)
The transmission in my Blazer was just rebuilt and the vacuum shifter on the front axle was also replaced. The problem I am having happened after a long 2 1/2 mile downhill in 4 wheel drive using high 4 wheel drive and second gear, when I reached the bottom of the downhill and applied power to start going up the hill I was approaching the transmission acted like it was in neutral and wouldn't drive in any gear. I stopped the car and checked the transmission fluid and it was full so I got back in and tried the gears again but still no drive, I was about to lock it up and walk when I pushed the button to get out of 4 wheel drive and the transmission immediately started working again and seemed normal so I shifted into 4 wheel drive again and everything seemed normal. The transmission worked fine getting out of the canyon later that night but did it again while going on a straight road with some moderate hills, after going down one I had to shift out of 4 wheel to get my transmission back.

Jan 16, 2008 (11:06 am)
I have a 96 Jimmy with180,000 miles have always had a bad vibration/shake felt through out vehicle after 65pmh wich comes and goes. Usually just driven in town until recent (driving 160 miles daily on freeway). I have tried changing tires,wheels,several rebalancing,new shocks, new transmision mount. The jimmy has been lowered 2", but did used angeled blocks. Mechanic has told me that I have two bad motor mounts and that could be the problem. They want $400 to replace mounts. Please some one help advise on this matter. Vibration starting to get to me.
