One thing I would suggest is instead of going through the filler cavity with atf , go through the sensor hole with 5w30 and use two and a half quarts because atf tends to evaporate with time. I really like your video! Great job
Definitely need to get this done on mine.
Important if you use your transfer case for sure
Great info!!! I’m gonna try a PPE trans filter that has more filtering capacity. I definitely need to do all fluids and filters.
Thank you! Trans and transfer cases are always over looked it seens
I change oil,oil filter,fuel filter,trans spin on filter every 4,000 miles. And every January 1st every single fluid is change! LB7's oil will always be clean unless there is a problem. Fumoto valve for the oil pain. Always remove fill plugs first on front,rear diffs and the tcase. About 200 miles before my oil changes I dump 2 cans of Seafoam in the crankcase and run it. Cleans the inside of the engine good. I sometimes even add a qt of diesel to the crankcase,then start the truck and let it idle for 5 to 10 minutes,then do a oil change.
Hell ya!
I have also used a full can of seafoam into the crankcase 100 miles prior to oil change, then replaced it with T-6 and PPE oil filter.
@@tedkay1048 it’s a great way to clean it!
Great video planning on doing my transmission fluid change soon way over due. Those hand pumps take long when you doing both differentials and transfer case!
Thank you! Deferential is the next one we will be doing it’s crazy how many people don’t ever do them
When changing tranny fluid, measure what you take out and replace with same amount, when you check your fluid level the truck must be running, and you should cycle for 5-10 seconds between reverse, drive and neutral. This evens out the fluid.
u should break loose the fill plug on transfer case first just in case if the plug is messed up if u drain it first then the fill plug is messed up you are screwed
Thank you that’s great advice. I have never thought of it like that 👍
What about differentials
Why didn’t you replace the internal transmission filter? It’s supposed to be replaced every 25k miles
That AC Delco is the new single pleat filter. The old style was double. I wouldn’t trust that filter unless that’s your only filter available. Racor fuel filter is the old style with double pleat.
I agree with this. When we bought this one racor was back order like 2 months and it actually took me 4 months to get mine.
@@DIYDiesel
I was told Champion makes this filter for GM. Racor is the OG filter & when GM switched they claim better water separation this model vs the old design. But we all know it’s cause of GM just being cheap & saving money on part manufacturing.
thank you for the helpful video. What truck are you working on?
This was on a 2007 gmc sierra LBZ Duramax
@@DIYDieselawesome thank you for your quick reply! I thought it looked pretty similar to my 2007 LMM.
I've always filled my allison in neutral as well, mostly because that's what EVERYBODY says to do. But on my dip stick it actually says to check it in park. Mine's an '08 but that shouldn't make a difference. I wonder why the mixed info...
So if it has been running you can check it in park, but if the fluid is cold you should check it in neutral.
Lol doesn't matter park/neutral. The trans pump is moving when the motor is running....this guy is a doink
so if atf is recomended,couldnt you just use the same transynd oil?
Yes you can
That was a lot of fluid to come out of the Transfer case, I thought it took like 3.2 pints... that looked like quarts..
Definitely quarts not pints 👍🏼
@@DIYDiesel AMSOIL has it on there site at 3.2 pints....for all 3 transfer cases... I did find on another site it says 2 quarts.... finding lots of different capacities for the Transfer case.. actually seeing 1.6 quarts for teh 2017-19 and 2 quarts for 2020 up
@@rayray1846 ya don’t do pints that will end badly for you it is definitely quarts all day long. Not sure why they have that like that
You still using shell Rotella? If so where are you buying it?
Currently we are using Farm Rated 15W-40 and it has been working great! We do plan to switch to Chevron Delo I am going to buy a drum. I have a friend that sells oils & lubes.
2.5 gallon jug of delvac 1300 at walmart is $31... this is what comes in them from the factory.
Why is 10w30 better for the transfer case?
It performs better in the cold weather.
Sorry but look at every possible filter breakdown comparison. Delco filters are terrible. Love your vid though, thanks for the Drain plug replacement tip.
So many fluids for transmission ?
Huh?
@@DIYDiesel sorry lol how many fluids for transmission? Thinking about doing it again since jiffylube just use the machine
@@MalikWong 7.4 quarts for a service change, and 12.7 quarts for a total capacity. 🤘
Why would people just motor oil if atf is recommended? Actually its autotrak fluid isnt it?
Atf is recommended by manufacturer, the 1500s use auto trak fluid. I have found the motor oil just shifts smoother especially in the winter months.
@@DIYDiesel ill try it out then, appreciate the guidance
@@DIYDiesel Would the valvoline maxlife auto transmission fluid work fine for the trans?
@@oof578 as long as it’s dexron
You move to fast when stop the additive product.
In regards to the fr3?
Absolutely ZERO reason to use stiction eliminator on a high pressure common rail diesel.. its not a heui..
That’s false it will help with the turbo lubrication. No it won’t help with anything else. TBN is the better oil additive to use for general oil changes.
@@DIYDiesel do you add the 2 oz for each quart with the oil or you take some oil out to add the stiction eliminator ?
Bye. Less hand jive next time.
Wix filter on a duramax = "Normally I act intelligently; yet, due to my complete lack of forward planning, I had to settle for the worst quality filter on earth." (Ref: every comparison video on TH-cam). Dude, you could have got a walmart supertech filter with more pleats than the shitwix. If you can drive local to get a shitwix, you can most certainly drive a slight ways more and get a wallytech. FFS!
You ok after that rant lol
