Routine Maintenance and running strong

[Dennis]

My 06 H3 has turned 68,000 m....I just gave it a little TLC to keep it running strong.

I imagine this is boring stuff to some of ya, but this is what I like to do to keep the old girl running strong and problem free...


1. Transmission got a BG Flush, Conditioning and Refill..(done every 30,000 miles)

2. Drained a refilled both Differentials (75w90 Royal Purple)(done every 30,000 miles)

3. Drained and refilled Transfer case ( GM Transmission and Transfer case fluid #88861800)(done every 30,000 miles)

4. Drained and refilled Engine Oil (5w30 Castrol Edge)(done every 6,000 miles)

Nice, to know there's other that take care of their vehicles I did all this right after I bought mine, it was a pre-owned 07 3 with 70 k on the dashboard and I didn't know how much service the prior owner or the dealer have done to it, and so I flushed and top up everything again. So far no prob.

I need to do my transmission... I did my brakes, power steering, transfer case and both diffs. when I got my 06 in the spring. I still gotta do the cooling system and transmission. Can you recommend that bg service? I did a little research and there's a few shops by me that offer that service.... Including a couple dealers. I've heard mixed reviews about "transfusions"...

When you did the t/case refill did you pull out the VSS and add extra fluid, or did you just fill to the fill plug level?

Remove the drain plug and allow the t/case to drain.
After draining fluid, install pipe sealant to the drain plug and torque to 18 lb ft or 25 N.m.
Remove the t/case fill plug, and fill to bottom of fill plug hole:
​for all 2006 Model Year Vehicles and for 2007 model year vehicles if the VIN is 56TDN13E778100102 or prior:
Remove the speed sensor connector (top rear of t/case), then remove the speed sensor.
Add 250 ml (8.45 oz) of manual transmission and transfer case fluid through the speed sensor hole.
Install the speed sensor and tighten to 13 lb ft or 17 N·m. Then install the speed sensor connector to the speed sensor.
This additional fluid is needed.

As for the BG service. Backflush is actually recommended by GM for their transmissions; however, do not use any cleaning solvent, the trans should be flushed with the same fluid you will end up with. That can be Dexron VI or another approved spec fluid.

Yes. I have a tag on the tcase instructing you to add the extra fluid through the speed sensor hole...

I see there's a conditioner added to the transmission with the fluid.. Is that ok? I assume yes since Dennis isn't having issues... Do they typically use a cleaner before pumping in new fluid?

I had this BG service initially done at 38,000 miles and BG warrantied the tranny up to $2000 for 30,000 miles and it came with roadside assistance too...so No problems then..I just did it again at 68,000 miles and the service backs the $2000 warranty again for another 30,000 miles...So it has worked well for me and with absolutely no problems, transmission is solid like a new one....I don't know when the conditioner or flushing is actually done or how it's done..I do know it is all done via the transmission cooler lines though....I was told also that if topping off is required, that Dexron VI is a compatible fluid to mix with the BG stuff....That makes sense now that I think about it..

BTW..This is all done at a GM/Hummer dealer/service.

From an ex-GM service engineer; the answer is no. But, not my trans! If you are running the correct spec trans fluid, as spec'ed out by GM, there is no need for any additives. Whether they will do harm or not, I have no idea, and neither does GM (I'm sure). There are probably a hundred different additives that are recommended by the manufacture of THAT additive or recommended by someone selling the product. Therefore, it would be impossible for GM to test all of these additives. However, their extensive testing pretty much shows a fluid meeting the required spec works pretty damn good. I have often wondered when these companies recommend a fluid, do they do any testing? I question that, but I be the answer is NO.
And since you are out of warranty...it's up to you.

However, I have had my trans flushed twice by the dealer and nothing but Dexron VI was used to flush or fill.

I'll add, that what a dealer recommends is not necessarily a GM approved service procedure. Believe me, GM dealers can come up with more BS in regard to servicing a vehicle than our President can produce. I know prior to having the dealer do my flush, I made sure he had the KM tool we tested at GM. But WTF does a retired GM service engineer know? And, like I said, it's your trans, do to it what you may.

I still believe you Doug.

Well like I said, I got my H3 in the spring so I rely a lot on you guys that have the experience with these things for advice and the safest course of action. I appreciate the feedback and certainly don't want to fork out money on repairs that could've been avoided. Especially in this day and age where there's more than one way to skin a cat... I plan to call the dealer and ask their process and see what they recommend.
So Dennis, did they fill your transmission with dex VI or use something they claim to be equivalent?

They used 16 quarts of GM Dexron VI, #88862155 in the process...

How much was it if you don't mind me asking?
