I switched back to 87 for a while and couldn't stand it. It felt like I was missing something. I'll have a good trip in a while and see if it'll still break 18 mpg. All the short 10 minute drives get me 14.

That's no good. Sorry to hear that Chris.

 

On another note, I swapped out my tcase for fun today. Thinking that bearing noise was coming from my output shaft bearing I swapped in my old tcase which was fine before I yanked it for no apparent reason. Well, the noise is either coming from the transmission or rear end. Please don't let it be the transmission

 

It is not rpm related but speed related. You can hear it at about 55+ gets real bad around 70-80. Not sure how it can only be speed related cause I held it in second gear at the general rpm and it didn't make the noise. Damn this sucks...

what you're talking about happened to ethan on his yukon and on his way up here memorial his transmission blew it was the output shaft... chunks of metal blew all over the inside of the trans into the pump everything.. even a chunk of the trans shell busted off... get under there and check that trans asap.

Its covered under warranty, I'll let them deal with it if it blows up. Just, it will blow when I need it the most lol. I just had the transfer case off, didn't really think to check the output shaft. I looked at it when I cleaned off the old gasket, but I didn't really inspect it. Really not up for the task of yanking that thing again.

 

Was his truck echoing it through the driveshaft, making it hard to pinpoint the noise? Cause like everyone knows, Ive basically replaced the entire drivetrain in the past 4 months so I didn't even think that it would be something to do with the transmission, ughhh

Yea same type of sound we thought it was the rear end too then he got on the highway doing 65 and boom no gears

You and your auto luck....Stay at least 10 feet from my vehicles at all times.

Another issue? Please just get rid of the truck already! :)

 

Find a clean low mileage example and enjoy it.

I'm looking man! And as long as stuff is covered under warranty I'll do the work. My labor is free and it's only $50 in fluids.

 

They say you can race on this transmission and not void warranty. The thing will chirp 35" tires pulling into second gear. I have a feeling that is part of the problem

Drive it like you stole it so you can get the work done already.

Gotta make it last so I can get another vehicle and then I will. I did the most conservative driving on the way to work this morning haha

Is it bad that I have an extra transmission sitting in my garage that I could put in this weekend? Haha

    • In the 6.6 gas thread, I added information in my fluid change thread about these gauges and temperatures. With very limited data, it so far looks like ~30 degrees difference between front and rear.
    • I know; crap pictures.   Anyway, as a finale of sorts to this thread, I had replaced both differential covers and since they had the capability of adding temperature probes, I did that. These are MaxTow analog/digital gauges with stepper motors. They'll flutter around like crazy for a moment and start at a nominal 100 degrees Fahrenheit.   I drove a 30-mile loop to the grocery store, averaging 70 MPH (as much as 80 to see if there was a quick spike in temperature. The air temperature is 102 (ambient ?). but the first pic is 7 miles into the trip. The second is getting back into the truck after leaving the store; differential temperatures dropped about three to four degrees in 15 minutes. The third pic in on the road to my house, about a mile away.   In that run, I saw a high of 150F on the rear differential, and 121F on the front. I'm sure a longer drive or towing will see higher than that, and when that happens, I can update the observations. 
    • You don't want to become predictable now, do you? 😏
    • Fully warm, coolant temp >194, closed loop.   Run time can be anywhere from just reached operating temperature to having driven 30+ miles.   The O2 chart (which is a feature I just discovered after reading) for the bad idle seems to be "most" of the time. For the little time I've been watching it (scanning and driving! watchout!) I can't seem to isolate any cause or condition yet.   It definitely idles rougher sometimes than others and so far what I've seen is the rougher idles are always rich. But not enough to set a CEL.   In other news I replaced the starter solenoid. Everything on this truck is such a PITA. Starter "snout" is mangled up with the torque converter inspection cover which is tangled up with hard cooling lines and the driveshaft. But I got 'er done without too much swearing...I just go into everything now knowing it's going to be a frustrating mess.   The starter solenoid replacement kicks off the next round of work: AC, injector rebuild, cat, exhaust. I'm just going to do it all. But first:   I don't know what my fuel pressures are. I can't definitively say the issue is the injector without first verifying fuel pressures and any leakdown. I "rented" a test kit ($199.99 at O'Really's ...intentional misspelling). They don't "rent" tools anymore, they charge you for the tool and then you return it when you're done. No joke. It is listed as a rental on the receipt but the guy told me there's no difference between renting and buying  now, you just return it when you're done and they refund the credit card. Mmmkay, whatever.   I will rule out fuel pressure issues (too much), and any leaking (that's how I'll know the problem is inside the intake). I think someone said the return line could be plugged or not flowing and that could cause high fuel pressure (and too much fuel being pushed through injectors). I'll cross that bridge if I get high readings.   As of now I'm ready to tear off the intake cover, extract the injector, and have it sent off to be rebuilt just so I can rule that out.
