Transmission
I had question I have a 03 Silverado 5.3l and I'm having
transmission problem it won't shift to 3rd and high rpms
that was today, yesterday it was changing to all shifts only
problem was it was with high rpm and it said transmission
hot then I stop let it cool down then I took off again and it
was running good for about 15 min and then it started to
go slow I was going 70mph and I could only go around 50
and I stop and checked trans fluid and there was a little of
fluid in it I put two bottles of trans fluid and took off and I
could only go 50mph or less today I went to a guy that fixes
trans and told me it doesn't go to over drive and he has to
rebuild the whole transmission is it true ?
