#3059 of 3449 Heater Core by 00jimmy Nov 05, 2007 (8:11 am)
The heater core went out on my 2000 Jimmy. It is currently disconnected, but I need to fix it soon. I have talked with some folks that suggest replacing the heater core THROUGH the fire wall. Has anyone tried this on a Jimmy?? Thanks in advance. Replies to this message: jmbeaz (Nov 05, 2007 6:37 pm)

#3062 of 3449 Gear ratio by twistkick Nov 08, 2007 (1:43 pm)
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? Replies to this message: jlflemmons (Nov 09, 2007 6:33 am)

Replying to: bigd1948 (Nov 06, 2007 5:28 pm) You mean just "soft but working fine" or "soft and to the floor?"   If you just feel the pedal depress a little when you start up, that's okay, that's just the power brake booster kicking in. If the brakes work fine and feel fine after that, you're okay.

Replying to: twistkick (Nov 08, 2007 1:43 pm) Inside the glove box is a white label listing all the options and configuration of the vehicle when built. Look for an option like "GU6". Here are most that I know of:   GT4 -- AXLE REAR, 3.73 RATIO GT5 -- AXLE REAR, 4.10 RATIO GU4 -- AXLE REAR, 3.08 RATIO GU5 -- AXLE REAR, 3.23 RATIO GU6 -- AXLE REAR, 3.42 RATIO G80 -- AXLE REAR, LIMITED SLIP (POSITRACTION)   Most common in the small Blazer/Jimmy 2wd is the GU6/3.42.
#3065 of 3449 DTC P1886 by johnnycage Nov 14, 2007 (5:49 pm)
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!!
