2003 Chevy Trailblazer 133000 miles.
Car was running fine then I had a misfire on cylinder # 6, we changed the spark plugs and coils and everything and it has never ran the same since. About 4 weeks later now it seems like sometimes when I get over 60 and I am going up a hill the transmission is not wanting to shift. I will have my petal to the floor and it will bearly go, if I let off the gas a second and push it again then it fixes it. The mechanic seems to think we need a transmissin flush but I'm scared that this is just something small and then the flush is going to creat a 2500.00 new transmission problem. I'm scared to keep driving it but it only does it sometimes. And I'm scared to have a transmission flush if it really don't need it. Can you please advise some.
