#118 of 384 front differential problem?
Dec 22, 2007 (7:51 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?

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..

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.

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.

This may help you, I had a problem with it not shifting and setting a check engine code. A friend of mine works for chevrolet we ended up replacing the wireharness from the fuse block or the connection block on the firewall, (sorry can not remember exactlly which one) to the transmission. The Dealer will know.This solved my problem. Hope this helps.

Check out my reply to psycodad, Not sure if it would be the same problem being that yours is a 2000 model. The 96 and 97's did have a problem with a bad transmission wireharness, It may be worth checking into.

Well...my tranny in my 97 GMC Jimmy finally went after 187,000 miles. It lived a good life. I've already ordered a rebuilt tranny and it's on it's way. My question is, do I need to lift up the engine to get it out? On some past tranny swaps like my Buick, I need to loosen and lift up the engine to drop the tranny. Just wondering if I need to borrow an engine hoist. Thanks for your help, Keith.

Sorry to hear your tranny finally gave up on you, anyway no you do not need to borrow an engine hoist. You should be able to unbolt and pull back and drop it down. when I changed mine out on my 96 thats all I had to do, although the top bolt on the driver side was a chore.
