The gears are slipping in my transmission when I am sitting in drive and what to throught a red light the car sits for a few seconds then goes. can it be my tramsmission flilter?

Have the trans service at a shop you can trust, it should be serviced every 50,000 mi. or so. also you better chk. it before you take it there, sounds like its low on fluid might acount for it slipping. just have fluid and filter chg. if it slips after that than a rebuild or replacement is in order no ajustments will fix that.

You should be changing your transmission filter once a year no matter what. Now that I'm off my soap box. You need to ajust the bands. When you pull the filter to your transmission there are going to be some bolts. You need to find the specs to your car and transmission and ajust them. If your transmission is not toast, this could fix it very cheap and easily. Also, have you checked the transmission fluid making sure you have the correct fluid?
