Time for reliabiality upgrade on my 18 5.3, going to delete dod, and replace converter. Whats the easiest way?


Recommended Posts

Posted (edited)

90k miles on my 18 1500 5.3/6 speed.  I know too may people with lifter problems to just keep driving it, and I'm terrified that the converter is going to wipe out the trans, even though I've changed fluid every 30k miles, and changed the thermostat.  I tow heavy a hand full of times a year (boat, skid steer, and mini ex).

 

Planning to do the work myself, and am comfortable doing it in my garage (without a lift).

 

Is there a preferred way to do both at the same time? It seems to me that pulling the engine would make sense.  I can swap the cam and lifters on a stand, and leave the trans/transfercase/driveline in the truck. 

 

Is there something I don't see making this a bad idea?

 

Is there a better way?

 

TIA

I was faced with the same dilemma with a different brand. You probably have passed the defective part test. If it was me. I would keep the oil changed and drive it.

Can't give much information about this, as I've never done either one myself. I wish there was an easy way to replace the TC. You either need to go from the back (pulling transmission & transfer case or from front by pulling the engine). I'm curious, did you ever do the AFM/DOD dis-engagement with an OBD2 device like "Ranger"? If you have, like I did, I agree with KARNUT above, to skip the DOD delete & TC replacement, since you did do the transmission thermostat delete & changed ATF every 30k. It's my belief the TC goes due to the high ATF temperatures. That's just my opinion. There's lots of videos on YouTube on both of these procedures. What new TC would you put in?

The vehicle I was referring to was my Odyssey. My father in law had the exact same model since new. He started burning oil at 100k miles and traded it in. He  followed the oil monitor. I do half or less. At 142k it doesn’t burn a drop. The transmission is fluid sensitive. Its first service is way too long. During slow speed up shift it shuttered. A complete fluid change fixed the problem. I’ll do it again in April one year later. Toyota and Volkswagen have similar maintenance schedules. It would be reasonable to trust their recommendations. Don’t. Always follow the extreme service schedule. I bulked when the Hyundai dealership recommended the extreme schedule with my wife’s Genesis since new. With their warranty I reluctantly did. It’s just under 4K miles for service. Twelve years and 132K miles the oil is never dirty. You have to use a white background to even see it. It’s not an DI engine so that helps.

Any one have a write up on pulling the engine?  surprisingly I haven't found much  on you tube

I have a 18 'Rado WT (Short Bed) L83, I just did the DOD delete, BTR Stage II cam w/lifters (will need new pushrods, will be a different length needed), new valve springs, Long tube headers, port polished heads. Watch Youtube videos for good info to watch out for, like removing oil pump, they make alignment tools to help with that, R+R motor is the best since the oil pan has to come off. If you remove the solenoids for the VLOM you'll need a plug to plug up the oil hole (see Youtube for VLOM oil plug). I also used studs for the heads instead of bolts. there are some fasteners you cannot reuse, be sure to look into that. you will have to install a VVT limiter and hope you have a HPTuner system, you will need it or someone who as one. But it is not that hard if you can wrench! good luck!

I plan on doing the DOD delete in the future with my '15 Silverado 6.2. I just replaced some bad lifters on passenger side. Since you want to do the delete, the easiest would be to remove the heads, ac compressor, vacuum pump while in the truck since they need to come off anyway. Once that is done, removing the engine is a lot easier. All that is left is Starter, cooler lines, bellhousing bolts, motor mount bolts, torque converter bolts, and some wires. Support the tranny and pull it out. With the engine out, you can do the torque converter and remove the engine oil pan to help deal with the oil pump. I may pull my engine if I have issues with the timing chain as shown in DOD videos.

Sounds like what I want/need to do in the near future. What kind of difference di it make? How does it affect daily drivability? MPG change much??

 

Thanks in advance,

    • I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.
    • I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments
    • Looks like the entire state is burning. 😬
    • Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
