On my way home last night I noticed my Blazer was not changing gears. When I stopped it was extremely difficult to get moving again, and when I got up to 55 the rpm was 2500. Usually when I get up to 55 the rpms read 1500 or a little lower.
We take really good care of the Blazer, always change oil, check the fluids..ect... and it has about 84,000 miles on it.
I have no idea what is wrong with it, as I am no car expert by far. My father says it has something to do w/ the computer, but he is not sure what. He said if the transmission blew, I could not move. And I defintly can, just always in third gear. When I manually put the Blazer in Gears 1 2 and 3, it works. But not when I have the Blazer in drive.
Does anyone have any possible ideas of what is wrong? Is it the transmission that blew, or is it something with the computer? Plz post!
