Good-on Rick Hendrick for stepping up for the charity to the tune of 3 million. It's not the first time he has bid (and gotten) significant vehicles with vin number 001; an avid collector and philanthropist.

Have your checked the throttle body for carbon build-up at the butterfly; could it be a physical hang up from an obstruction? And have you checked for vacuum leak?

I would not be adverse to using the transmission to slow and maintain my vehicle speed on an extended downhill section though I would think this would be an exception rather than the rule if braking was adequate and not sustained. (kind of what is stated in most driver's manuals; sustained downhill should downshift accordingly) Excerpt from XT5 manual: • Know how to go down hills. The most important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill.

I've seen that deliveries have finally begun and the "V"s have been getting into owners hands. What I fear though is the they might be discontinued (the CT6) and might leave the Blackwing an orphan; that would be a shame for this awesome engine. It is also my understanding that this is an exclusive engine for Cadillac and will not be shared with other GM brands. I've also heard that the flat plane C8 upcoming ZO6 will have an double overhead cam engine but it is not related to the Blackwing. I hope they find a home for the Blackwing (ultimately with the continuation of the CT6-V or the CT6 Platinum with the detuned Blackwing.

Thanks Bruce. I've seen this one before but watched it again. Some very good information and advice to be heeded. I've always kept my oil changes under what the oil life monitor suggested and have never had this stretching issue. I've had the 3.6 in three flavors; in my '06 STS (LY7), '11 STS (LLT), 17 XT5 (LGX) and currently in my CT6 '19 (LGX). Fingers crossed but don't think I'm going to have the problem.

I went to Amazon, type: NorthStar water pump tool and got this: https://www.amazon.com/ k=northstar+water+pump+tool&crid=2U0J3O5J1Q60O&sprefix=northstar+water%2Caps%2C184&ref=nb_sb_ss_i_1_15 Does this help. Looks to be Lisle 14440

Have you checked for vacuum leaks. I'm just a 'shade-tree' and will yield to our real techs out there.

Well, right off, you're going from a CUV to a sedan. The CT6 is quieter, more sure footed (the XT5 is fine but the CT6 is almost on rails). I'll miss my heated steering wheel but the CT6 still has heated seats. The CT6 has the lane keep, front braking etc. (as an option) that my XT5 didn't have but I don't think I was missing it before. The CT6 has the same six (though longitudinal opposed to transverse), now have a ten speed tranny as opposed the eight of the XT5 and the CT6 has rear biased all wheel drive. I'll probably have more as I get used to the new ride but in a nut-shell; I liked the XT5 a lot but I think I'm going to love the CT6.

Update: I just traded my '17 XT5 Luxury for a '19 CT6 Luxury. I didn't get the Lux/Prem (cost) but I got a good deal on the '19. It is the white/pearl and actually has less equipment than the XT5 but I wanted to get back into a sedan (and the trade-in and price fit the bill) so here I am.

Good point Bruce (about having to telling someone how good you are doing). Communication is 'key', and even if the news isn't always the best, just letting your public know what the heck is going on is key to retaining that connection and sometimes their business. p.s. I'll try to reach that story again; maybe a problem on my end. I appreciate the link (in any event).

Subscription required; no joy (for me). Cadillac, I think, has been pretty poor in its direction and especially in sharing what the heck is going on. I refer to the orphaning of the XTS, don't know what's going on with the future of CT6, CT4 and 5 coming with no details or direction and the announcement of all the electric future with nary a word since. This just my opinion. I certainly don't expect to hear any of its secrets, but I don't appreciate the information void either.

I've seen these self help video for parasitic battery drain; this one is the best one so far.

………...and they haven't shipped any CT6 V's yet (or CT6's with the Blackwing). I think some buyers say by the end of August for the V's release (some have been built but held back from release).

Concur with you Bruce; other than knowing that they are working on them, not much revealed. And you certainly may be right on your engine predictions. Maybe "Blackwings" in the future but I don't think right out of the gate (but that's pure conjecture on my part).

A Google search for: "instrument cluster repair" should give you a great starting point. Some sites even help, per your location.
