I drove my explorer last night and thought of something. I have been driving with overdrive on. I turned overdrive off and there wasn't any slipping or clunking, but the shifts seemed a little rough. Another thing I noticed was, is that when I "gun" it and at around the 2nd gear or so I feel a little resistance or scratchy noise for about 3 seconds and then it goes away once it reaches the next gear. I don't know if this has to do with the transmission or engine. Also, everytime I punch the gas I hear a little scratchy noise in the front end that sounds similar to a diesel accelerating. Does this sound like an issue?
All the help is appreciated.
