Hmm.
Billy . . . your descriptions make it sometimes sound like multiple causes transmission issues; then sometimes like an antilock brake or anti-skid control issue locking up the brakes.

You defiantly need to use a mid-level scanner for codes and live data.
I now use a once was top level $300. scanner. INNOVA 5160
Past the codes, live data while someone else is driving tells stories too.
$300+ level scanners buys you into the scanner brand manufacture help support.

Once you can get codes search up Internet owners support groups. Look for topic with the number codes and symptoms. You are looking for pattern failures. With proven fixes.
How I found out about GM front wheel drive’s with lock up torque converters NOT unlocking killing the engine at stops. Then restart up and drive fine. Ha! I kept looking for ignition problems! Wrong. (That would be GM FWD hot soak engine mounted ignition failures. Open hood testing, letting out heat, and you never find these.)

Billy, you haven’t written anything about the vehicle, otherwise it’s hard to give any clever advice. Maybe if you look at the scheme of the automatic transmission, maybe you could measure some voltage on the solenoid valve, …, maybe the pressure of the control oil fluctuates - clogged filter, … maybe the pressure regulator, … loading and guessing, … what about Jakob thoughts ,…

Sorry to not get back sooner. I went out to try bobs idea. Started the car, it tried to move but not really. This time heard some obvious mechanical problem noise. So we pulled the pan and found the teeth from one of the converter splines…I think… So we pulled the at and are waiting for a converter.
I still have a fear that it was the teeth of one of the planetary gears… But since we didn’t find any evidence at all of any metal fragments anywhere else in the system that we can see without pulling the front pump, were going to take a chance on the$90 converter and see what happens

Hey Billy with an auto transmission taken out, now’s the time to flush the cooler and lines.
Use a siphon air gun. Clean, new, Stoddard solvent. Or clean new lamp oil.
Then flush that out with a quart of siphoned up heated ATF.
S.U.

Opps. I should have added trying to flush both ways. Most, with rare exceptions, once clean should flow equal both ways. S.U.

[BillyAlabama (Billy North)]

Yes sir. definately. on the flush

Finally tore it down and found gear tetth everywhere. I think it is the reverse planetary set that came apart.

WARNING!

I have another mechanic question.
This one is for those of you who like puzzles.

EDIT: I think I figured this out, but I’ll leave this up for those who might be interested. the answer is at the vvery bottom.

Does anyone out there have some good general knowledge about 2013 era chevy (malibu) 4- cylengines …

GM can’t seem to help me. I got myself into one of those “help-a-friend-of-a-friend” deals…AARRRGGG!

The short of it is this:
Exhaust camshaft-driven Vacuum pump came apart and broke the position sensor counter off the camshaft. caused an oil leak and a CPS code. I intended to replace a seal and sensor as a favor kind of thing.
Bu, Since no good deed goes unpunished, when I pulled the pump to fix the seal…

I ordered a camshaft by the VIN. It was not slotted, but I used the orientation of the counter to weld my counter on and it did not work.

I then used a picture of a 2.5l cam to orient it and tried again, it is obviously not firing at the right time. Like in the old days when you would install a distributor 90 out or something.

Now the real problem.
GM will not even touch the engine…replacement only. so guess who gets to tear it apart…Yay!

Now for the really real problem.

VIN and hood sticker call for a 2.0l engine.
But the GM diagrams, online diagrams, and actual parts bought for 2.0l do not fit. Camshaft for 2.0l is not slotted for the vacuum pump.

According to GM there were 4 engines available (4cyls):

1. 2.0l which has turbo and seems to have no vacuum pump (but not sure)
2. 2.4l with direct injection, non-turbo, totally different vac pump and head and valve cover, etc…= very different in appearance
3. 2.4l non-direct injection, similar in appearance but not turbo and not slotted camshaft
4. 2.5l slotted camshaft like I have, vacuum pump like I have, but pics of application in used cars differ with air ducting, hoses, etc… And the orientation of the counter does not seem to work correct.

One other piece of info. The car drove to the shop. It died a few times as it set cam position codes, but it was running, so it is unlikely that there is other significant mechanical failure, i.e. broken cam shaft, jumped time, etc.

also, Coils and plugs are firing, and noid pulse is injecting fuel…so I didn’t fry anything when welding the counter on. It just seems to be doing those functions at the wrong time.

So, does anyone out there have any experience here. My thought is that someone pulled a 2.0l out and slid a 2.5l in its place, leaving the turbo…but It seems like it would be a lot of work to do so.

At this point I am open to most anything. The customer would like to put a used engine in it and move on, but I can’t really identify the engine well enough at this point to replace it. I suppose that is the real question I am asking; what engine am I dealing with here. ANy ideas on how to figure it out. ?

Edit: I just received a diagram from GM that pretty clearly eliminates the 2.4l, as the head and VC is totally different, no vac pump, etc…

EDIT: ANswer…2 parts
Two different GM parts departments sent me the wrong diagram for the 2.0l head assy. Turns out their computer system is wrong. They have the pictures for the 2.5l in the directory for the 2.0l so that when you look at the diagram for the 2.0l you are actually seeing what looks like a 2.5l. It is also the same diagram system that all the online parts aftermarket companies are using for identification.
This is apparently a system flaw globally for GM. At least that’s what one of the parts managers told me.

2nd part of the answer. The camshaft I ordered for a 2.0l from an aftermarket dealer because GM has discontinued it,…was actually the wrong part. They sent me a cam for a 2.4l direct injection engine.

SO, both of my “believed-to-be” acurrate measuring sticks were wrong. I think we figured it out. It is simply a 2.0l engine as the VIN and hood sticker call for.

It is funny too, yesterday my son said, “Dad, are you sure it’s a zebra and not a hidden horse”. I was sure it was a zebra…LOL. But, no, it’s just a horse and a couple folks who are a certain part of a horse.

Replace it with an Iron Duke and get rid of all the sensors and other annoying crap.

I haven’t posted much recently but i have been busy. We have finally gotten a dozer over here to do a few big projects. this one is the pond/ dam /road. Our property is split into two halves by a valley with a small creek in it. We are putting a road in to the back side of the property. the first few are in the valley and the rest Are from out back coming in from the other direction. i will try to get more pics tomorrow. we finished the road today.

[Norman89 (Marcus Norman)]

Looks like a d4 cat?

[JocundJake (Jakob North)]

Some sort of Komatsu, some reason d51 comes to mind.

[Norman89 (Marcus Norman)]

Ah ya I ran one of those looks very similar to the cats, one I ran had a enclosed cab an ac, was sweet building road with it

[JocundJake (Jakob North)]

this one is an old machine it was built bare bones no extras but it runs very well and works well. It is a little small for some of out big hard woods and bedrock but im not complaining it better than trying to do it all with mu skid steer. We tried clearing out the creek bottom today got stuck twice decided to call it. we will have to figure out another way to get that done.

[Bobmac (Robert Mackey)]

You have been very busy indeed. What are the trees that you are removing. Look like gasifer wood to me. Chunka chunka chunk. DOW

[don_mannes (Don Mannes (West Michigan))]

Can you hire Wayne’s beavers to build your dam?

[JocundJake (Jakob North)]

the saw logs we are stacking up, the fire wood worth poles we are hauling to the firewood processing area, or we are hauling them to grandparents or neighbors. that is what that one dump truck load was and there has been many more. the small limbs and the stumps are just getting shoved off in the woods. we had to haul a few loads of them at first to the edge of another field before we had a place to put them close by.

[JocundJake (Jakob North)]

probably could if we could catch them. it might be hard to drive over one they built . we used to have beaver in this creek when i was very young but they moved out. We actually used to have a bunch of them, there is an old beaver dam about 500 yards from where we are putting it the dam. it will probably get flooded when we finish ours.

[tcholton717 (Tom Holton)]

I know you guys stay very busy, but you should consider making Hugelkultur beds out of some of that stuff you are just shoving into the woods. Worth the effort or at least worth studying.

How to Make Hugelkultur Beds for Growing Vegetables

[JocundJake (Jakob North)]

We also use the poplar that is two small for saw logs to grow mushrooms. we stack it out in the woods and it will eventually start growing oyster mushrooms.

[Norman89 (Marcus Norman)]

Get rid of poplar+ grow oysters= a big fat win in my book!

[JocundJake (Jakob North)]

Another update.

We finished with the dozer work. the pond is not built but we can’t get in with the dozer to do it. We sunk it twice trying about 10 min apart and decided to stop. We will have to get a trackhoe in to do the rest of it.
I did some forging and Jesse smelted some aluminum.

A little out dated event but i realized i never posted it. we butchered and roasted a hog for a community event. we finished the smoker. Luke and I and the young boys roasted it overnight.

We keep building wood crates as we can.

I got an old disk out of a scrap pile and we got it put back together.
