Hello guys,
I have a 2012 chevy Silverado. Single cab, 8ft box. It has the 5.3L with manual 4x4 on the floor. I got the transmission serviced at 43,000 miles and the shop said there was a substantial amount of metal that came out. From what I have been reading people are saying that's just because it was the first service, other people are saying that the transmission is eating itself? Opinions? \

Thanks, Ethan

 

ask them to show you the "substantial amount of metal".

 

yep. pics needed.

 

What Tech2 and MMJ said.

Any new transmission, automatic or manual has to "break-in" so the first fluid change will have break-in metal as part of the flush. If its a NV-3500 it should have a magnet on the drain plug, or at least my Chevy 1998 K-1500 pickup does, but cant say about a 2012. I would highly recommend using a fully-synthetic,Syncromesh fluid on refill, not any kind of ATF fluid.I use Royal Purple Synchromesh fluid. Expensive, yes, but she shifts as smooth as silk.

 

Ok I will call them and ask them what they put it. I'm Leaning more towards it just being the break in period. I don't know what they put in but should I add some additive next time or change the fluid again?

 

They didn't take pictures, just wrote it on the receipt

 

He called me and told me that because I told him I was taking it to NC the next day. She made it out and back this fine. 2700 miles. He just wrote it on the sheet. Could it just be break in period?

 

Also need to know if it's steel, or brass, could be sync gear break in.

 

Ok I should call them and ask them what it was then

if you are not having any trans problems and no dtc are settting….drive it. If it is showing problems...it needs a teardown. If it fails...its needs a teardown. Its the same boat regardless.
