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.

      TCM Tuning 6L80E

      By Grumpy Bear · Posted

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
