2015 silverado

[Colby Roberts]

I have a 2015 Silverado 5.3 I have reverse gear but no forward. Pulled apart TCM found no issues. Was finally dumbfounded and took truck to the shop. They said they replaced torque converter, transmission pump, and TCM. Said reverse still works strong, they said they put it in drive and it engaged but as soon as they hit the gas it fell out of gear. What could this be so I can make a suggestion to these guys

Suggestion. 

Go to school to be a mechanic. Frfr. Did they charge you? They should be able to connect it to a computer and diagnose.

Snowcamo they said they found the problem which they didnt think it would be because of the symptoms but they mentioned something about the drums and clutches and stuff and they said they wont charge me any extra because they didnt think it would be that issue. I'm going pick her up tomorrow

Well, they sold you a bunch of pretty expensive parts when they fired their parts cannon at your truck, which didn't actually fix things.

 

Replacing the TC doesn't make a lot of sense if truck has reverse but not forward (as it works the same regardless of which direction the truck is moving).  Same with the pump.  And the TCM failing is way down the list of things that go wrong...

 

Those are just expensive, relatively easy to change parts, that were unlikely to be the problem.

 

I would suggest never using that shop again, as they either don't know how to diagnose problems, or just don't want to (they'd rather fire the parts cannon at it).  And ask for your old parts back.  Unless you got rebuilt parts, which the invoice should say that, they HAVE to give you the old parts.

I know there's a vid on YouTube about this issue. Give me a bit to find it. It'll be simple enough to understand.

Yea thats cool man. It's free tho right? The vid still applies to your situation as you can see how the fluid pressure applies to the clutches in the drums.

Glad your back on the road.
