Finally replaced the gear lube in Blue Beauty this weekend. GM synthetic out and Red Line in. Took for a short drive to top off the tank and sling the lube around for monday morning. Better Half came home tonight and almost gave a wow - she said the 3 felt effortless. Didn't do the tcase with Redline D4. While reviewing the shop manual noticed the pipe thread comment (bought some today almost $30 full retail for a little tube, but who pays retail these days).
Another gotcha on the tcase, the vin reflects the possible newer case, there is no blue dot, but there is a sticker saying to add the 8 ounces through the speed sensor. Pulled out copies of posts from fstop on the other forum about this issue. Based on the wow comment the D4 is going in the fill hole or 1.5L of D4 or whatever I feel like.
Keep reading jeeper comments on the jk and looking at another h. Dang if only could get the best of both worlds. The general engine, tran, computers, the jeep history, support, sfa - dang dang dang

Was it months ago on the other forum where the topic was transfer case. A tcase failed around 90K miles? and another about 38k miles? Just changed blue beauty's tcase fluid to D4 redline. Have the sticker but the vin above the change so took off the fill plug first and sure enough out came about eight ounces. Always take the fill plug off first. Saw the plastic sending unit, disconnected it but didn't attempt to take it out. Easy for everything, no jacks needed and plenty of room just doing too much lately and you know that last little thing when your tired really sends the day downhill fast.
The fluid was dirty. I don't remember the tcase (nv241 or nv242?) in the crd being dirty. Advice on the other forum was to change it out. I wish I had made time to do it earlier. Aluminum drain and fill plugs with that expensive teflon sealant really dried on - used an old brass brush to try and clean some of it off - just added a little more and installed them - probably too tight - too lazy to get the three eights torque wrench out.

Came back from doing our part to keep the economy going and decided to take better half to gas up the 3 tonight instead of the solo sunday routine. Went wow. Pulled over let her drive her dd and she went wow. Wish I could let you drive and feel the floating drivetrain and listen to the running gear that is now quiet. Sold on redline. Maybe amsoil has the same effect. Can't wait to do the tranny. Glad the dif's were done first so I could see the effect of each change. Unbelieveably finer than new. mpg's slightly better and expect even more now that the tcase isn't sucking energy.
#52 of 80 2007 H2 has no electrical power
Feb 01, 2009 (8:40 am)
I just purchased a new 2007 H2 about 10 days ago. Today I went to start it and nothing happens. I cannot move the shifter out of park, the vehicle will not release the key from the ignition. There are NO lights or horn, the only thing that lights up is the engine light. I am thinking its the battery, but on cars of the past you can at least hear the starter clicking, but I get nothing. Obviously a call to the dealer is in order, other than that any ideas from anyone?

depends on how much juice is left in the battery. If this is a brand new H2 than I'm guessing the sitting for 2 years on the lot in all weather has done the job to it.
#54 of 80 Instrument Panel
Mar 30, 2009 (3:25 pm)
I have an 03 H2, and the instrument panel has been going completely blank. Mostly, when I start, none of the gauges work. Sometimes if I hits the right pothole, everything comes on. But usually stays blank for several trips.
I had a fender bender a few months ago, and it has acted this way since.
I suspect a broken electrical connection or loose plug.

I had the same problem. There is a fuse panel under the hood on the left side. There is a fuse for each pin on the multi-plug for the trailer connection.
It is a common problem if any stray wire shorts against the frame of the trailer.

I purchased a 2003 H2, right around when the H2 was just released. The car about a year, year and a half ago has been rusting on the entire under carriage of the car. The dealership never wanted to do anything reasonable towards a trade in (for a new one without rust), and the car was out of warranty. Anyone else have this similar problem?
I'm thinking about trading it into Toyota for a Sequoia and letting it be there problem. Too bad the Hummer is fun to drive.
#57 of 80 Oil Change Message
Aug 31, 2009 (6:12 pm)
I have 38,000 miles on my 2006 H3. I regulary chage oil every 3-4 thousand miles. Few days ago I got the message on the display saying "OIL CHANGE". What does this means.

Sounds like whoever changes your oil didn't reset the oil change message.
