I have a 22 silverado with the 10 speed. While sitting in park or neutral it acts as if it is trying to engage. I can monitor data and number 2 solenoid is energized sometimes for a few seconds up to several minutes. Once it de-energizes it stops trying to engage. I can not find theory of operation as when clutch solenoids energize. I replaced TCM but still does it. I know they have had problems with the valve body but would that cause the shift solenoid to show power?

I am not sure if this problem is related 

 

I had valve body failures 4 times before getting rid of truck. Each time the check engine light would come on. Sometimes staying on, most time going out within 50 miles. Sometimes I would get a loss of power, other times truck would not back up, another time it would not move. 

 

 

GMC is very dealer based and I could not talked to them directly. The 800 number person would say talk to dealer about warranty and suck. Dealer was not very good. In the end I was out 1500 dollars .

I don't think this is a valve body issue. I monitored clutch data and it doesn't show pressure on the clutchs when it acts up. I also don't have check engine light. I think it is something in the clutch drum I had it idling in neutral and it just started going 40 mph like it was in gear.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.

      OCI, not when but why?

      @Grumpy Bear the conclusion from your post about doubling engine life has me curious. Are we literally talking an expected life of 250,000 miles potentially becomes 500,000 miles with a step up in filtration for fresh oil at "the oil factory" when it's bottled? I know you said that's a single variable among many, but, that's significant if the implication extends that far into a real world use case. I would think the oil marketing folks would really eat that up and make it known.   Particles introduced during oil change is a fairly easy one to avoid, but probably not intuitive as one would think. I.e. using a clean funnel. But...what was it wiped with? Paper towel leaves behind little fibers. A solvent if not dried is not something one would want to introduce into their engine with clean oil. And, keeping the oil filler neck clean and free of buildup.. Look at some guys engine bays and they're an absolute mess. Some say that's better than the drawbacks of cleaning it. I'm not a buyer of that idea.   I've also wondered if "flooding" the top end of the engine with oil while filling is a bad idea. During normal lubrication the oil flows in a gutter back into the galleys. But if you flood the area you're potentially washing the top of the rockers, springs, and other areas which may not get much oil wash normally, and you're mixing all that into the new oil. I just don't have the patience to pour slowly. 😆

      DTC P2C48 auxiliary cooling pump

      By Newduramaxh*ar · Posted

      It was a bad pump, i had a dealer next day the pump. Gm part #86591535. Tools needed 10mm socket, pliers for hose clamps, 1/2gal of Dexcool. About 30mins to remove and install, pump located near oil filter on driver's side frame rail. I had a local mobile mechanic delete the code, he had a snap on scan tool. My scanner could not delete the code. I drove back home about 700 miles since then, and no check engine light. Hope this helps someone in the future in the same situation i was in. Thank you to all that helped me.
