    Thoughts on a transmission drop and refill

    Why I am asking is due to hearing and reading various opinions because of the high mileage. Even when I first bought it I was skeptical because you hear mixed opinions on this topic. But I posted on here due to the history of this model transmission.

    Thoughts on a transmission drop and refill

    Hello guys. I know I'm probably going to get possibly mixed responses. But I'm going to ask anyway. My 2008 Denali xl awd has 231k miles, bought at 219k miles. Seems to shift great and no issues. I put roughly 5k and year on it and have owned it 4 years. I have changed all the other driveline...

    AGM battery in 2011 Denali?

    Hello folks. I have a 2011 yukon denali xl. Would it be OK to use the AGM style battery in it? I've read mixed opinions? Don't see what it would hurt. Thanks.

    Hello fellas. Had a quick question. I got 2 ac Delco oil filters through Walmart. Of course they always seem to be out of these filters. Anyway. Did they change the 8 digit part number for retailers? Also did they change the design?

    Towing a trailer

    Hello fellas. Got a question. Got a 2011 yukon denali xl awd. What is the largest camper I could tow with this vehicle. The one I was looking at weighs 7555 pounds. It is the Kodiak Ultimate 3321BHSL. Any experience is welcome. Thanks.

    Oil pump

    No shaking idles like a Swiss watch. I have read about it reading low of course researching. But I guess my next question would that be a bad thing if I did down the road installed the high volume high pressure pump?

    Oil pump

    Yes the needle goes up past the 40 psi. I have read that the pressure is low at idle. But when setting at a light tonight it seemed really low. However it is really hot and muggy and figure that may be why? Again, it did go back up to normal. I'll have to see if my scan tool will show that I...

    Oil pump

    Got a question. My 2008 denali xl 6.2 with 222k oil pressure at idle read half way between zero and 40 at a stop and the goes past that once you start moving. Is that normal, I know it's been really hot and muggy weather also. Should I consider maybe throwing a new one in and also would it hurt...

    Service suspension light still on

    I meant I removed the 4 level sensors with those links not any computer module. Just the compressor, level sensor links and of course the shocks/quickstruts and coil springs. I've tried researching what the resistance would be to see if I could just put a resistor in place of the link level...

    Service suspension light still on

    Where is the suspension module? I removed it because I wanted to have nothing there that wasn't needed. Also I did read the directions and thought the resistors were the only thing needed. The other reason was I also really cleaned under the vehicle to get it nice.

    Service suspension light still on

    As far as codes. It was all 4 corner sensor faults, compressor and one other. Can't remember. I'll just live with it I suppose.

    Service suspension light still on

    Oops. I yanked all 4 off and tossed them out... there probably isn't anything that I can do at this point I suppose. I wondered if that would possibly be of issue.

    Service suspension light still on

    Ok. I got an 08 yukon denali xl. Last year I installed the monroe conversion kit and completely removed the air compressor, the level sensors and pulled the compressor fuse. I did not at the time (last year) install the supplied resistors. I had too many other things going on. Fast forward to...

    GM converter upgrade question

    Hello folks. Have a Hopefully simple question to ask. My 2008 Denali has 220k. Runs smooth no issues shifts fine also. However I'm contemplating if I should upgrade the torque converter with the GM Zl1 style converter. The transmission fluid is dark and I figured maybe this would be cheap...

    220k mile Potential purchase

    That's why I'm just gonna keep looking maybe one with half the mileage and same good condition. Plus at one point when I reversed and stopped the oil pressure gauge went whacky?? This was when I was on a snow filled parking lot checking the 4 wheeldrive stuff. It sis run real good thought and...
