I’ve got a 2016 lml, and when I bought it GM said to change it around 45,000 miles. Do you think me letting it go that long has hurt it? Im about to start doing it as you suggested. Thanks!
I’m definitely going to start doing it with my fuel filters, which is every 10,000 like you said. Hopefully I haven’t hurt my trans by this point. Thanks!
@@jameswalker4123 oi the 2005 eqanox you have to do it every 30,000 but you cant check it so might as well do it every 15,000 to 20,000 but if youhave a dipstick you can check it and if its brown change it and if its darker brown change it if its getting off red change it if its black change it with added lub for next 5 changes i change my z28 fluid every 10,000 and its about 9 bottles and its 10 bucks a bottle HAHAHA so yeah but i know my gears are running red and what not and you can use dex 6 for me thats what i use i dont know if diesel is different fluid for trans but all other chevys its all dex 6 now unless its other t1 stuff THE END ::))
I just replaced the one the factory put on in my 2005 duramax with 275,000 but I would say it’s the having a tune for 1,000ft lbs an the trans not being built is my main issue.... haha
Thanks for your help on maintenance information. I just bought a 2017 Chevrolet 2500 Duramax truck. It’s a High Country with only 70,000 miles on it. This was a one owner truck. I’m new to the diesel world, I’m big on schedule maintenance on my vehicles. 👍
For whats it's worth, I change my Allison spin on filter every 25k miles and top off with Transynd. Every 100k, I drain the system and refill. Every 200k I double drain and do the internal filter. My Allison made it to 1.2 million miles of towing pretty heavy and often before getting a rebuild. LB7 now has 1.3 million on the odometer.
Good idea! I was doing it every 30,000 miles, but will change it at 10,000 miles on my 2005 GMC 2500. I wish all AUTO XMSN filters were this easy to change. I have over 350K miles on this XMSN, and it is still performing great. I also use synthetic Dexron III fluid in it, not the super expensive Allison TranSynd fluid, and it works just fine. No issues at all. And, I read that GM drains the Transynd fluid at the factory, and replaces it with Dexron III before the new trucks leave to be delivered at a dealership..
Transynd is PAO and is superior to that swarf you’re pouring in your transmission. GM wouldn’t pour our transynd to replace fluids…I heard GM recycles every 2nd truck as it leaves the assembly line too.
GM recommends 22,500 for fuel filter. The dash DIC matches that. Some guys I know do every 15,000. It will be worse the colder climate you live in. As for the spin on, I do every 10-12.5k miles…. It’s really easy…
Good video just curious though if you’re not sure on what fluid was put in the truck originally be it AC Delco or transynd or some other fluid is it OK to mix fluids as long as it’s dexron VI since a little bit of fluid drops out when you change the filter?
Glad I subscribed Outstanding Info Do you recommend a warm up before changing filter and fluid? I am going to drop fluid in pan as well Will 2 gallons do the change? Thanks for all you do.
Great video I have 12,500 miles in my Allison since spin on and fluid changed Will do the spin on Allison Duramax said 30,000 to 40,000 miles to do the Fluid change Thoughts?
Great stuff However I was ready to change fluid and filter But looked at Dip Stick and that fluid looks Brand New Crystal Clean Last year put 700 miles 1 trip Year before that 2000 miles 2008 Truck only had 61K org miles And has been. Well maintained by a Diesel Mechanic So am thinking wait and out a few more miles on before change out. Have all the All Parts Thanks for your great video
I usually don’t change the fluid warm, and I might be wrong on this. However, it doesn’t matter what I do or what precautions I take, I usually wind up WEARING about half of the transmission fluid. It never fails. So for me personally, I don’t change it warm.
Check the diesel supplemental guide for your truck. It will suggest normal and severe duty intervals. I always follow the severe duty schedule for additional peace of mind.
After how many filter changes should you top off or should you top off every filter change and about how much fluid do you believe you loose in the filter when removing it
I believe you lose about 8-10 ounces per swap. So a quart of ATF will do you for up to four filter changes. You can check the stick for level, but it is really difficult to read IMHO.
Hey I have a 2019 Chevy 3500hd dually and only 17k miles on it I am the only one that had the truck only pull a 8.5x24 trailer here and there and the transmission is slipping And changing gears rough just took it to the shop yesterday they asking me if I added some kind of additive Because the fluid seems thick When they rub their fingers together And I ask them why would I add something when it’s a brand new truck so now I got to see what they say today
Have you checked fluid. Nothing in this installation would have affected your shifting unless you have some something to block fluid flow. I suggest taking it back down and checking your work.
@@thoroughbreddiesel If he followed your recommendation to flush it, that is where the transmission got F-ed up. Never "Flush" an automatic transmission!
Are you in a regen? That definitely seems to make the shifting less smooth…. Other than that, make sure you are not low or overfill of level on tranny…
Embarrassed to say I was always advised not to mess with a transmission unless ABSOLUTELY necessary. Hence my LMM has not seen a trans filter change since I've owned it at 100k... and she just rolled 203k last week! I'm guessing my magnet might have a shaving or two on it!!!
@James Motes Well good luck to both of us then. I was gonna see if I could find an upgrade kit for the trans as I hear they help a good bit. I got EFI live right now with a man-back exhaust and Banks Cold air intake with superscoop. About to hook up my Air Dog 2 finally and we'll see if that'll save the ole CP3. Not sure if it helps or hurts. And EFI live also provided a Trans tune which I'd say is a defenite plus but does take some getting used to. Anyway, as I said before, good luck, and with any bit of it we won't be stranded after this!!! P.S. 315K... impressive.
What kinda annoys me is why trucks don't remind you of the 5:58 service intervals for everything including the transmitter filter (my truck is 2022) as it does oil fuel air filters brakes etc. To me that's kind of misleading. . Well know I know
That fluid gets absolutely boiling hot as you drive, (like you could cook fritters in it after getting to your destination). The heat ruins it over time, turning it into varnish.
Great suggestion, I've been doing it for 25+ years, and I'm always amazed how easy it is. Always said I'd just keep a Maintenance Log on my truck, but sadly, I never did. Just relied on my parts receipts. Dang, now I have to change my fuel filter!
Only one I've ever seen is the big Allison. Drain plug and outside filter. I had an outside drain cap and magnet set up in an ancient Chrysler transmission many years ago and never needed it. Honda puts their literally thimble size inline transmission filter buried inside the case. Once it's plugged, the unit fails. Very handy.
Actually the maintenance interval is 30k on the spin on filter and 100k for the internal as per GM maintenance schedule. Don't use aftermarket filters. Either use the Allison filter or the ac delco filter available at GM dealerships. Also drain the dexron fluid and upgrade to Castrol 668 ATF . The difference between original dex 3 or dex 6 ATF and the Castrol Trans Synd 668 is the service mileage. Dex 3 is 30 k miles, dex 6 is 100k miles, Castrol trans synd 668 mileage is 300k miles.
Catapilar technicians claim too never fill your filter with oil and reasoning was contaminated oil gets on the clean side and then is cycled through the motor/transmissions! They claim this was worse then the few seconds the motor would run with out oil too the top end ! I've always filled my filters and still do but hey they are the technicians lol!
Team Deep Tillage The cat guys are right of your not carful or don’t use a filter filler. Dirt is worse for wearing parts then air is. But if you make sure to put the oil into the filter in the proper place or use a filler then you have no dirt and no air.
Good video. Probably should’ve mentioned that you would need to check the transmission fluid level after replacing a filter because of the fluid that drained out.
@@1DirtyMutt Still a good idea to check the fluid level. I just wasted a few minutes watching this because checking the level was my goal. unscrewing a filter shouldn't take any directions. Lefty loosey, righty tighty.
@@thetexorcist2235 I have 3 Duramax trucks. To get the correct reading on the transmission. There is a specific proceedure spelled out in my owners manual.
We usually change the external filter every other oil change. As for fluid and filter, I would suggest changing both at 50K miles. Cheap insurance for a healthy trans.
It becomes plugged eventually. Once 'plugged up' the gunk just recirculating around causing more damage. I would personally think about drainage of the original (probably brown stinky) original fluid and refill with fresh, and maybe even a bottle of Lucas for transmission. I put almost 2 in a small GM 4L60e giving old age problems and it helped. If the fluid in yours is smelling nice but dark that's a good sign. Stinky means it's fried
HANDY TIP Take a plastic bag (Like the ones you get in the produce section of the grocery store and hold the filter with the bag wrapped around the filter as you take the filter off. NO ATF dripping down your arm, only dripping into the bag you wrapped around the filter. :)
Damn I have 410k on my 01. All original motor and trans. I changed mine every 30-40k miles lol. Hell maybe I should do every other oil change so I can get 600k out of it
RU-vid TFLT Alison in everything. The life of the transmission depends mostly on the calibration. The same transmission last over a million miles in a medium duty truck all because of the calibrations.. Sad but TRUE!!!
I am a stickler for oil and filter changes..have an 02 LB7 that just rolled 357,000 miles today..orignal engine..orignal trans...change oil and oil every 3000 miles..Allison spin on every 5000 miles..drop trans pan and install new internal filter and new spin on every 25,000/30,000 miles..front rear,diffs every year..run a Fass Ti150 /Beans Sump 10 micron water Sep and 2 micron fuel filter those get changed every 6000 miles or sooner..sometimes before an oil change I dump a can of seafoam in the crankcase.Installed new injectors June 2018 and took pictures of underneath the valve cover..spotless! Seafoam put my truck in there winter time magazine or Instagram post in December I think.white 02 with 350,000 miles at the time!! Maintenance is cheap insurance. Wix oil,fuel filters Allison brand spin on Mobil 15w40 1300 delvac 2.5 jug
I found that magnet and was surprised. I cleaned it off and put it back on, then decided to research. Looks like i did the right thing. This explains why the drain plug doesn't have a magnetic tip. THANK YOU!
After seeing this video I bought transmission filters for my 2021 GMC Duramax 3500 because I’ve never changed. Bought truck new. Is it possible I don’t have an external transmission filter? I can’t find anywhere.
Thank you for making this video. I am a fairly new Duramax Diesel owner. I also thought all the trans fluid would drain out. That looks easier than an oil change or fuel filter change, I do both of those on my own. I will be doing this right away and often. Thanks again!
You won't drain out more than half, because the torque converter is not being drained. The best you can do is drain it. Drive it for a month, then drain it again, where you are increasing the percentage of older fluid to newer fluid. In most cases, that is enough.
Question i have is that i bought a 2016 lml and it has 120k on it. I contacted the previous owner and the trans has never been serviced at all. Is it a good idea to replace that filter. I really want to do a full service but have always heard if its never been done don't do it
If its never been serviced, it needs to be serviced. That old wives tale will not apply to automatic transmissions. Need to service the external and internal filters as well.
Just a little hint A break the filter loose but not leaking I take a small Phillips bottle of my hand I just bumped the screwdriver up into the bottom of the filter then I loosen the filter oil runs out that holds that all around the top not quite so messy you don’t have to wait for the whole thing to drain just wait for it to leak down below sea level I found it be easier to be neat and clean enjoyed your video
Yes, you can fire up right after the change. The pump will refill the filter, but we suggest you checking the fluid level and refilling to the correct level.
I got over 102,000 miles on my lmm with 0 trans fluid or filter changes and it’s just fine. Gm recommends not replacing the fluid and filter til 150,00 miles and I’m no where near that.
No, You need to make sure that this spin on filter is more than hand tight or it will leak over time. Snug it with a filter wrench. If you don't believe me be my guest and hand tighten only.
You aint loosing that much fluid and honestly, if you're that worried about how much you lost. Well, fill the new filter with transmission fluid and spin it on. That's how much fluid you lost.
GM doesn’t recommend swapping the internal, until you run into a rebuildable situation. That filter is way more coarse, and would only catch some things from a failure. In other words, don’t worry about it IMHO.
Great video buddy.... one question u don’t lose enough trans fluid to worry about adding? Or should I fill the filter up mines a 2020 so I can’t add from top it’s upfill I guess
He's an old school mechanic. Most guys about 40 and older grew up working on vehicles without gloves. I tried using gloves but just can't seem to get used to them. It just doesn't feel right. So, I keep a big container of Gojo handy.
This is all new to me. My ‘20 Duramax is my first diesel since my ‘97 Ford. My truck has reminders for fuel filter, def, oil change, air filter, etc., but nothing on a Trans Filter. Also, my truck has 49k miles on it, and all my service work, from oil changes, to tires is done at my local Chevy dealership. If this is so important, why has no one from the dealership ever mentioned it, and why is there no notification warning as there is for everything else? Is GM deliberately trying to hide this from us, ‘cause it wouldn’t surprise me? I’m not trying to be argumentative, just trying to follow this to its logical conclusion. Thanks!
i guess im asking, for a good guide or routie to get started, fluid change ... flush? the truck used to be a lease truck, and plenty of dealership matiance but dont see anythign about tranny service. 150k miles what to service?
If you are changing this filter every 10,000 miles, at 100K you would have swapped almost 3 quarts of fluid, which is just under 1/2 capacity. Another reason to change the filter regularly!!!
For an oil filter that is vertical or on a diagonal, I'll take a large nail & w/ a hammer pierce the center(or lowest point) of the filter housing to let the fluid drain...then remove. If you're in a hurry; let the oil drain from the filter for 15-25 seconds, then plug the hole w/ a wood dowel & remove the filter. The filter in the video is small so it'll only take a minute to flow to a drip. I've been doing this on the huge oil filter on my IH/Ford 7.3 Diesel. Keeps the work area & me much cleaner.
@@carmiethompson2676 this is a horrible idea, the first time the filter is siezed on there and you can’t get it off now you can’t take the truck anywhere to get fixed or go buy a different tool to help get it off yourself or even come back to it . Make sure the filter will come off first .
@@michaelhuss8551 What are you talking about? When does a spin-on oil filter 'seize' on the threads of the filter mount? Don't take your Meds before you post, that's a horrible idea!
Ok so I just bought a 2500 HD I did all the fluid changes . Bought a magnet for. The trans filter. When I did the fuel filter .. I noticed it had no water sensor or separator on it. At this moment I still Have 41% oil life left. Today I got all my oil and filters. I plan on getting aid dog set up. When I do what do I do with factory set up. How do I block it or get rid of it? Ty 2005 Chevy HD
The factory filter should have a water separator built in... big plastic screw with a wire coming out on bottom of filter. Lots of companies make filter delete kits, basically a metel bowl that goes in place of filter
I bought my my Wife's Friends Late Husband's very clean 2011 Silverado HD 6.6L Duramax w/only 98K. I'm fixin to change out the Trans, Fuel, Oil & Filters out at 100K. Oh yea, I'm swapping out the Worst designed GM Trough Oil Pan too. w/ a PPE deep flat bottom Pan. Former Owner kept it in great Service condition, but I still want to know I' m doing my Do Diligence to hopefully get at least 200K + mi. out of it with proper servicing & Maint. Thanks for your Vlogs, I'm really learning a lot here viewing your Videos as this is my first Diesel.
