car has 245K miles on it and I want to go to RedLine synthetic trans fluid (or something better, any suggestions??). The trans also leaks a bit of fluid. Main reason for change is age of trans and it slips a little, and hesitates sometimes. SO, a couple of questions- who has done this, is it recommended/beneficial? And if so, any tips/tricks to actually changing it myself? Tools? New filter? Any suggestions are welcomed. TIA
