I have a '97 GMC Jimmy that needs a new rear end. I was told I need to find out the gear ratio to make sure I get the right parts. How do I find the information I need?

| Hello, I have a 1996 Chevy Blazer4X4 I have had for about 4 years now with no problems. It has about 157,000 miles on it. And I never use the 4x4 option. Recently the Service Engine Soon light came on. I took it in for a free diagnostic check at a local shop. He told me the service code he got was a P1886, and has a issue with the 2-3 shift solenoid on my automatic trans. I did know the transmission had started to react very slow on the start when this light came on. And it never engages in overdrive now. Whats really odd is when I start it in the morning, or even shut if off for a few minutes. The trans shifts great. Then it slowly starts to get in the mode of high RPM to get the truck moving from a traffic light. If I manually shift from 1-2 there is no change and the engine RPM's hi. But when I go from 2-3, it is hard on the trans in shifting. The shop said the trans looks very good. But suggests a shift solenoid to be replaced. And he said he can clean out the solenoid for under a $100 dollars to see if it helps. He claims it is next to the valve body under the pan. Is this something I can do? I'm pretty handy with taking apart the car in most repairs. I believe the trans I have is a 4L60 but I am not sure. Let me know if the shop said was OK, and if possible for me to do it myself, to save the extra bucks in these hard times. Thanks Much!! | |

I've got a '96 Blazer 4x4, 4.3L, V-6, LS. Bought it used in '98, had 35K miles on it, and it's been pretty good to me, but it's now got a little over 100K on it, and the problems have started. Here's my problem: Every time I start the engine, the #4 fuse (gauges) blows out, the daytime running lights go out, the dash lights go out, and it drains the battery right down in no time. Put a new alternator in today, new spark plugs, plug wires, distributor cap and rotor, oil filter and oil changed. Apparently, none of those things helped at all, and it looks like it's an electrical problem, but I have absolutely NO idea of where to look for a short or wire damage first. Electrical is not our strong suit, but pretty handy with most other things and a quick learner. Has anyone else had a similar problem or heard of anything like this? I would appreciate any help, because we're both stumped here and are running low on spare fuses. Please, please help!

Thanks for all the help, guys, but we managed to find the problem on our own. Oddly enough (or maybe not), it was the ignition switch. I didn't think of that before because I didn't have any problems with the Blazer's starting, and it wasn't stalling, either. Nonetheless, all the weird and funky electrical/fuse-blowing problems were coming from a bad ignition switch. Just thought I'd post the solution in case anyone has/or will have a similar problem.

Hi, I have a 98 Blazer 4.3 LT. The problem with it, is that the 4WD not working. I've checked, and found out that the switch on the dash work, the box under the RH kick panel work, the transfer case work, the vacuum actuator work (pulls the wire real strong).... So I've figured out that the problem should be in the front axle? What is the wire from the vacuum actuator connected to in the front axle? Is there something in the front axle that use to break down? Something easy fixed? Someone had that problem before? I´m quite handy, so fixing it might be simple, just want to know how it works in the axle. Someone that has had this problem before? Or know how it works in the front axle, please help... Any explode wiews of the front axle to wiew somewhere on the internet? Thanks, Magnus
