Transmission
I have a 07 Silverado 4.8 nnbs 1500 an today I turned on
the truck an put it in to gear an it shifted really hard. I
drove down the street an the truck felt like shutting off. My
lights on my dash board all went to zero then my service
transmission light came on I parked the truck an turned it
off. Then I turned it on an my trucks Rpms reved high i
checked the fluids on the truck an the transmission oil
was a little low so I topped it off any suggestions???
