after starting blazer(automatic) in morning and putting it in reverse, it feels like it sort of does small jerky lunges a few times and seems like it might quit. problem goes away when I put it into drive and does not happen again during the day. Not happening everyday - just some mornings. Transmission is just a few years old. Could it be a transmission problem or possibly fuel system? sorry if vague - hard to describe
have you had the transmission serviced lately. I usually recommend a service every 15k miles or once a year if the fluid is getting dark or smells burnt.
I’ll give it a shot and get back to you - thanks
