1st Gear going bad?

STINSAN3 · July 3, 2014

Okay guys, I think my 1st gear is going out or something. It started last Friday & it's only happened 4 times since then. If I'm at a redlight or in very slow traffic. Once I get hit the gas pedal, my RPMs go up and that's it. I shift it into Park then it back into Drive, everything works as it should.

The last time it happened when I was leaving Advance Auto today, (had to pick up some air fresheners & K&N cleaner for my intake), but anyways started to pull out and boom, nothing happened. I was like you gotta be kidding me. But then once again I shifted into Park and then Drive. Everything seemed to work. Only does it every now and then.

So, what do you guys think it is? I'm just afraid my transmission is going out. But, my truck is an '07 Silverado 5.3 170K with 4.56 gears. Any advice or anyone know what's going on? Thanks.

Checked the fluid level?

170k's is quiet a lot. Maybe it's time.

I spend 3.5 G's on my old '07 with 185k's (km ).

Ok, mine was toast/toast. Including broken bearings etc.

so long

Maybe it can check the linkage adjustment if there is any or are vehicles wire/electronically controlled now days?
Sychronizer?

Sychronizer?

These have been shift by wire for years and controlled by a module , there is a shift cable and a switch on the shifter shaft which tells the gear selected by the driver to the computer ,

You can't do anything , as said , take it in

Just really don't have the money atm. Take it to a Chevy dealer or an actual transmission place?

If a dealer has a dedicated tranny guy then yes

My fluids are good and nothing smells burnt.
Just don't have the money to take it in.
Could be the transfer?

Your wasting your time and money. If you want to make any progress at all take to dealer and scan it. Then determine what you want to do. It wont fix it self

STINSAN3 · July 22, 2014

I'm just saying man, I don't have the money to take it up there & where I don't live with my Dad. I don't have anything to drive in the mean time.

Wish i could be more help but there is nothing more we can do here. You'll have to have the codes pulled at gm 90$. It may be something simple but we do not know. Good luck

STINSAN3 · July 23, 2014

It's not throwing any codes, though.

Who scanned it?

02suburbanZ71 · July 23, 2014

STINSAN3 ,,, this is the best i can do. read all of these PDF's and try to diagnose it yourself. IF you had gm scan the truck with no codes it might be electrical. perhaps a bad computer... be sure to read all of these and report back after you try the steps.
