Hello all I just finished a 2500 mile trip from Seattle to Anchorage and I have noticed that my tranny is slow to downshift out of 4th. I almost have to floor it and then sometimes it goes to second. Also while driving in traffic it does not seem to shift smoothly sometimes. Other times it works like a charm. Is the end of my tranny near? Would it help to change out the fluid and put Redline or Mobil1 in? I've only had this car for 2 weeks but already im glad I bought that extended warrantee.
