What did you do to your OBS GMT400 Tahoe/Yukon Today?

[Squirrelsmith]

Looks good. In regards to the lengths, it looks to me like the rear two want to trade maybe?

i replaced them one at a time and just chose the new one with the closest length. problem was the last one was way long so that may not have been the best way to do it. but it's reasonable enough i will probably just leave it

Have you noticed any difference in performance with the msd ignition? My stock coil has been annoying the past several years because it's whining in the speakers, especially now that I have a cb radio it's even worse.

i used the same wires with an msd blaster coil and msd streetfire dizzy. i may have noticed a little but definitely a smoother idle. i was really impressed with the dizzy right away. however 9 mons later when the rotor plate started seperating from the shaft and ripped itself apart then i was not.

so here is my what did i do today for my tahoe. i ordered anzo headlight turn signal assemblies and new stock taillights. cover king spicer mesh front seat covers. headlight and rear wiper switches from rock auto. and also some new door striker pins.

Sold it tonight. Goodbye Yukon. You served us well in the 18 months and 18k miles that we had you. Treat your new owners well!

Hey everyone. I took an ownership hiatus from March 2015 until today. I had a ‘99 Yukon that I bought in 2013 and kept until March 2015. I bought it to tow a 24’ travel trailer with. We took it on a 6k trip from Colorado to Maine and back. Then I sold it

I just bought my cousin’s 1997 Tahoe 4 door 4WD with 173k. He bought it in 2000 as a lease turn in. I’ve got some basic stuff to do (steering position sensor, fluid changes, etc.) and then I’ll make it into a mild off-roader. I’m excited to be back

this referring to me? no not at all, i just did it more as a maintenance thing since it was all original stuff. well not the spark plugs but i'm pretty sure the rest was

We replaced the fuel pump/sending unit in my truck this weekend. Now I have to replace the oil pressure switch as the truck won't crank up now. Checked the relay, it was not actually plugged in correctly and it fired up after that. Then this morning nada. Thankfully the OPS isn't difficult to change or get a hold of. Going to try jumping the switch first to make sure that is it. Now if I can find time to install my new headliner, right rear panel, a pillars and c pillars I robbed from a 95 Yukon at LKQ, I'll be most happy.

Replaced Oil pressure sensor, cranks right up. Runs a little smoother and the gas gauge seems pretty accurate. It does dance a little but doesn't make half tank swings anymore. Thinking this weekend is going to be inside work as the hubby is at hunt camp and it's going to be blowing too hard to take the boat out.

Installed corvette servo with 4th gear apply piston.
For those interested in my Tahoe it did not just come right out. Their is a metal shield over part of the floorboard I had to get a big hammer and long punch and pound it out some then bend another thin heat shield and I had just enough room to wiggle it out.
The new blue o-ring is so tight that I needed a crowbar to press the cover back in, good news was it held it there while I installed the snap ring.
I already had the BB tune which sped up the shifts so this wasn't a huge difference but I like it and given that I don't like real hard shifts (old shift kits) this is just perfect.

On a side note I noticed the 4th gear apply piston is made by Superior-Transmissions and they are located here in Tallahassee. I am pretty sure I see a nice older model Chevy pickup on my way home all the time with Superior-Transmissions logo on the back window, lol small world.
When I do the Denali I'll see if I can everything from them instead of ordering from Oregon.

I had the newly installed driving and fog lights aimed, and an alarm/remote start installed.

I was having a lot of trouble with accidently unlocking the tailgate window with the stock fob. Another reason I prefer the barn doors. Oh well.

I talked with my cousin and he hadn’t had any services done on the Tahoe in quite a while. I took it in today for an oil change and fluid changes on the differentials and transfer case. While taking the rear diff cover off, the shop busted the brake line. So, I ended up getting two new rear brake lines free of charge today. I had them flush the front brake lines as well.

 

[dkknaebel]

Replaced the headliner with the great one I found at LKQ. Replaced the a-pillars, the right rear panel, changed out my overhead console and replaced my alternator. I have a friend that pulled his 5.7L Tbi motor out of his 94 1500 and let me pulled all of the goodies off of it I wanted. Got a new alternator, TBI, intake manifold, exhaust manifolds, distributor/cap/rotor and some plug wires. And the whole wiring harness in case any of my plugs go bad. When we swapped out my steering box, the tie rods got out of whack (previous shop screwed that up) so the hubby lined them back up and went and got a new alignment done. Really happy my steering wheel is correct now instead of 90 degrees off. In a couple weeks, we'll swap out my intake manifold and the newer TBI, my truck has this weird flutter at idle at stoplights. Won't do it in the driveway while in park, has to be in drive to get it to do it. My intake had a big gouge on the top, we filled in with JB weld and sanded smooth, it might be the culprit. We'll see in a few.

Where did the gouge come from? If it didn't go through to internal than I don't know how a gouge would actually cause your issues..

It looks like someone took a pry bar to the top and tried to pry off the gasket and TBI.

What year? I vaguely remember something about something in the trans being vacuum actuated when in gear, in park itll run fine but put it in gear and it stutters... its been 20+ years since Ive really ‘worked’ on anything tho and even then it may have been my old dodge pickup.... sucks getting old

It's a 1995, it has the 4l60e and the NP241C t-case, manual shift 4WD and that might be something to look at. When it stutters in drive at a stoplight, sometimes it feels like it pops out of gear or kind of sits down, if that makes sense.

 

[Jon Valera]

So im looking into doing this same mod to my OBS Limited 2000 Tahoe. If i can ask what year avalanche is that console from and what kind of mods did you need to do to it to make it fit to the floor and to flush mount to the dash bottom piece? Great look.

I mistook where your gouge was. That will cause issues.

 

[the 18th letter]

Got the black beauty back on the road. New brake line, fuel pump repair, brakes rotors and calipers. Added some blinker fluid as well since she's been sitting a while

 

[latvius]

In the process of removing the transmission, so far I have the driveshafts, transfer case, exhaust, and starter removed. All I have left is the bell housing bolts and should be ready to pull.
