6.6 Diesel service

[cam02ss]

I have an '06 3500 Duramax with the Allison transmission that just turned over 90k miles. Bought the truck a couple years back with 59k, been changing the oil ever 10k, etc. Does anyone know the proper maintenance "schedules" for these trucks? I called one of the local dealerships and to me surprise they weren't very helpful. You know..100k mile service, fluids flush,etc. crap like that.

Transmission should be every 5 years or 60k miles
Coolant 5 years or 100k miles
Power steering as needed.. I'd say 100k us a good time to do it
Brake fluid I recommend every other year because of the hydraulic fluid absorbing so much moisture.

I do the spin on tranny filter every other fuel filter which is changed ever other oil change but I do my oil changes every 3k give or take some. I'm at 90k now so I'm due up to flush the allison and change the filter in the pan.

Good to know, I'll get on that

Get a service manual on Ebay or online. There has never been a case of too much maintence.

Since you probably dont know if they've been done, also change the fluid in your differentials and the transfer case. In addition to everything mentioned above.

speaking of the transfer case....there's something I've been putting off for a long ass time that I need to get on at some point. I need to do the pump rub fix before I have an issue with it. Just not on the top of my "to do" list but it's something I gotta get too soon.

Forgot about those.... Thank you!

Transfer cases need love too !!

Right, I'm almost at 91k now...I'm going to have all the above mentioned service done when it rolls over 100k. Any if you guys have your trucks lifted? Mine is leveled with H2 rims and 35s...thought about doing a 4" lift but dunno what brands are good. I'm new to this diesel stuff...

[0rion]

I just cranked the bars on mine enough to clear 285 tires. I have a 5th wheel camper so lifting is not a good option for me. Lift kits are like a lot of things.....you'll hear 10 different opions from 10 different people as to which one they like. The to of my list would be BDS, fabtech, and cognito. I like the BDS because it keeps the factory track width on the fronts instead of having the front tires track wider than the rears.

What do you recommend as far as a tuner? Here are a couple pics of the truck

Do what everyone else does, send it to Steve @ Frost.

unless it's something new for him I don't think Steve does diesel tuning. Diesels are a completely different animal. A lot of gm guys use edge for a handheld and IMO they're a pretty neat little tool. Much different than handhelds for gas cars. The juice with attitude has a ton of features but is pretty pricey. EFIlive is the other popular option and there are several guys that either mail order tune or will sell you tunes. You can also learn it yourself but there's not as much info out there for diesel tuning as there is for gas. Check out alligatorperformance......they have several tuning options there.

By tuning I meant programmers- sorry. Anyone familiar with these?

dont wast your cash on a hand programere the only up side to one is you can read codes look at duramaxtuners.com for a efilive tune like the stuff frost is doing for are ls cars. and 0rion that pump rub fix take about 4 hours and if you dont fix it befor it is to late you are looking at lest an extra $450 trust me it happend to me.
also op the filter you need to replace the most will end up being the fuel and its always a good idea to keep a spare when it gets cold out. im changing my oil 1 time a year or 10 to 15k
