I am at 95K miles on the 07 Classic Silverado and starting to do things I think need completed.  Here is a list of what I think needs done.  Let me know if I am missing anything or really don't need to do at this mileage.

 

Completing draining the diffs and t-case this weekend. Where can i find the correct torque for the plugs and cover bolts?  15 Ft Lbs for T case plugs?  Diff plugs 24 Ft Lbs. Rear diff cover 30 Foot LBS and plug 24 Lbs?  This sound correct.

 

Tranny Service-  dealer told me today they only flush and don’t change the filter as their machine cleans the filter during the flush.  Told them I have heard horror stories after flush and was told that was years ago.  Now new machine no issues and it cleans the filter as well without removing pan.  Also, they told me dropping pan and change filter costs more than the 250.00 flush.  So, looked at tranny but don't know if I can do it or not.  Just got truck in my garage and will need to put on jack stands.  What is the process or troubles dropping the pan and getting it back on?  I see the exhaust may need to be disconnected from manifolds.

 

P/S flush – How difficult?  Will I get air in system after?

 

Brake Flush and coolant flush are things I am looking to have done as well.  Any suggestions on these?

 

Only thing else I can think of is spark plugs and wires even though truck is running fine.

 

Any input to help out so I don’t pay an arm and leg for these services?

 

Thanks.

Transmission,

Drop the pan, new filter and refill. NO flush IMO.

The exhaust maybe a problem.

My 2012 I had to undo the transmission cross member support, hold the trans up with a floor jack and pry the exhaust out of the way to get the pan off.

Mine has the flexible exhaust connector by the exhaust manifold so I could pry just enough to get the pan off.

If you don't want to do it yourself check out a local shop, Grease Monkey, Aamco.

 

Plugs and wires, yes IMO.

Coolant.

P/S Steering , look on YouTube for a video on it.

Brake flush is easy with two people.

 

If your capable  do it all and save some money.

flushing a transmission at 95K ? Do you pull a heavy trailer? or drive it like a car ? Are you planning on keeping the truck forever ? I would never flush a transmission unless its been in flood waters I've had many Chevy trucks go 250k to 300k just dropping the pan and changing the tranny oil in the pan with filter Flushing is a waste of time on a tranny that's not giving trouble Also I've never had problems getting the pan off on several model yrs as for service intervals I go  50k to 60 k seems to be about right for me

PS fluid, can do it a little at a time using the "turkey baster" method...no need to get fancy.

Agree with pan drop and filter only...

Brake fluid may be an issue if bleeders haven't been out in a while.

The flushing the trans thing started when they quit putting drain plugs in the torque converters. It's usually not necessary unless the trans has failed in some way, burned the fluid or clutches. Pan drop and filter change should be fine.

      6.2L L87 Powertrain Engine Noise (Lifter Failure) Question

      By clowe1243 · Posted

      Got the truck back today.  Called them yesterday to get an update, and miraculously my truck is finished?!?! The $13k out the door was complete bullshit!  Ended up being over $14k.  They added some bullshit service bulletin that I cant even find, where they replaced my radiator without telling me or asking me, and charging me for it.  Need to do more research into it, cause they leaked the first delivered radiator was ran over by FedEX.  Sounds like bullshit to me. 2.5 Months for an engine swap, which ended up being remanufactured, not new; ****ing ridiculous.  Brakes are squishy as hell, not sure if its from sitting.  Will give a couple days to see it that figures it self out.  GAVE IT BACK TO ME WITH 1 GALLON OF GAS!  Just filled the tank the day before drop off, more bullshit.  My dash cam SD card was formatted, not really much I can do about that. 3 year, 100k GM warranty at least.  Time to sell it and say **** off to GM.  Bad experience.  Cant wait for the survey email to come through.  Overpriced Raptor R, here I come!

      Radio Update

      If I forget the phone in the truck, and forget the truck in the phone, and reconnect.  It works great for the day.  Truck sits overnight, and the next day is a no go.  It will connect Android Auto via usb cable, but not bluetooth.   Ive tried Everything in this thread so far, and nothing works for more than a day.   I think I might have to go to the dealer and have them flash the pcm.   thanks for all the suggestions guys. 👍

      primary drive belt tensioner

      By Bill Lemmond · Posted

      2022 2500HD Crew Z71 Duramax single alternator.  Recently had the primary (water pump / fan) belt tensioner pulley bearing to fail while hundreds of miles from home of course the plastic pulley melted and belt shredded which took out some wiring. Found a replacement tensioner assembly and belt to continue now would like to find a replacement for just the pulley and bearing to have a spare assembly in case of a repeat, the rest of the tensioner is fine. Has anybody here found a correct replacement part for just the pulley and bearing? Any help is appreciated.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Atlas · Posted

      +1 for the 3.0   Perfect for 1500 pickup towing duties.   Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town.   It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether.   Drive one, I think you'll like it, though...

      Metal shavings on dipstick and filter

      I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.
