    90K miles on original tires. Any one using Michelins Cross Climate2 tires?

    I always rotate front to back & not side to side but I run directional tires normally. Here's a compare of these 2 tires. Big weight difference between the 2 as well...

    There are just some days I wish I didn't turn wrenches

    My son was a tech for 8 years at a Chevy dealership and got all the TSing jobs that others couldn't do. The dealership was always trying to get free labor from the techs and the pay was so low. I got him a job at my work (Semiconductor) and he tripled his pay the 1st year. With the hourly...

    1st time replacing 10 speed fluid & filter

    I did a good snug. Been turning wrenches for 50 years+ so have learned that tighter isn't always better. If using a torque wrench I would go slightly under spec.

    1st time replacing 10 speed fluid & filter

    I reused the trans filter bolts. Before doing my trans fluid & filter I ran a few errands to get that trans temp up. It's nice having the trans temp gauge by selecting tow mode.

    AFM FOR MY 2015 Yukon Denali

    With just AFM turned off with a tune my mpg increased by .2mpg based on 30,000 average for each. With non AFM cam & lifters swap after 2,000 miles my mpg increase by 2+mpg. I have several 100+mph burst with 1 reaching the 140 mph speedometer limit easily with power to spare. The extra power...

    AFM FOR MY 2015 Yukon Denali

    Correct, AFM has been turned off for the last 33,000 miles. My drive to work is about 25 miles each way & 27ish typical if I don't hit many red lights. I've driven 2,000 miles since the AFM cam delete & very impressed with the results. With 2x daily remote starts due to frozen windshield &...

    AFM lifter fail on my 2018 Yukon Denali

    I only bought the cam from them & bought parts separately which ended up being cheaper for me. Make sure to get AC Delco lifter trays as some of those cheaper ones may allow the lifter to rotate & fail. You should replaced GM Genuine Parts 12589016 Camshaft Retainer The seal on mine was pretty...

    AFM lifter fail on my 2018 Yukon Denali

    That 4572 cam was backordered everywhere so I got the cam in link below which is in stock. https://sdparts.com/i-24504579-sdpc-sdr29512-l86-gen-v-dod-afm-delete-camshaft.html?q=Afm+delete I plugged the AFM oil ports then installed the AFM valley cover & everything is connected even though it's...

    Wish these transmissions had a dipstick tube.

    1st time replacing 10 speed fluid & filter

    The only sketchy part is disconnecting then reconnecting the transmission return line. I use a small pick with a curved end to partial remove the "don't lose me" clip then grab it with a needle nose. There may be a tool that slips over the return line that slides in to release the clip...

    My neighbor paid $800 to get his 2018 Silverado transmission fluid & filter replaced.

    1st time replacing 10 speed fluid & filter

    If you have a 10 speed it has 2 magnets in there. Before dropping the 10 speed pan I started the engine & let 3 qts drain, turned off engine then dropped the pan. The pan drops easily once you disconnect (1 bolt) the trans cooling lines from the side of the transmission.

    1st time replacing 10 speed fluid & filter

    I filled directly into the fill port while the engine was running and the trans return line disconnected. Once 10qts were added I turned off the engine, reconnected the trans return line, started up the engine then added the remaining trans fluid.

    2018 Yukon, tune to help trans?

    The reverse flush will help clean your filter if you don't want to drop the pan & replace it. I always do a forward flush after changing the filter by disconnecting the transmission return line from the radiator, stick a 3/8" hose in the radiator fitting, start the engine & let trans fluid...

    2018 Yukon, tune to help trans?

    For $300 are they doing a full 11qt flush or just dropping the pan, replacing the filter then adding 4qts? That's a 10 minute job on the 10 speeds. My neighbor paid $800 for a full trans flush & filter on his 2018 8 speed. I did my 10 speed last week & took 90 minutes & even did a tire...

    AFM lifter fail on my 2018 Yukon Denali

    Doing some 100+ mph pulls on the Yukon I got a couple of cylinder #1 misfires. Found some arc traces on #1 spark plug which was new 1,500 miles ago so I replaced it & all is good again. New parts going bad is so common & frustrating. 2/3 of my drive to work is a curvy hilly hwy that goes thru...

    Got my Tune On!

    I found a 6 lug 14 bolt 4.10 posi at a local junk yard. Removed the drum brakes & grabbed some disc brakes all for $125 then installed in my 1999 Suburban. Also pulled 3.73 gears from a low mileage 10 bolt Escalade for $50 for my 73 Camaro build. For the Suburban the 4.10 gears were better...

    There are just some days I wish I didn't turn wrenches

    I don't normally work on other people's vehicles but the doctor my wife works in the same office with wanted to replace the head gasket on his Land Cruiser and asked if I would supervise. That was an entertaining experience but got it done. Shortly after he drove cross country with it. He...

    1st time replacing 10 speed fluid & filter

    Check your quote, it's likely just drop the pan, replace filter then add 4qts. It takes longer to put the vehicle on 4 jack stands than drop the pan, replace filter then add the 4qts. If it was $255 for full transmission flush & filter I might let them do it. That is still $130 more that what...

    10 speed requires ULV, 8 speed uses Dexron VI
