SYNTHETICS , TRANNY & REAREND ??
first off i have searched , could not find what i was looking for . i will be changing tranny oil [ T5 ] and rear end oil soon . has any one changed to synthetic and noticed a difference ? smoother shifting ? smoother , quieter drive train ? is it worth the difference ? [ i am a cruiser not a racer ] just want to baby my baby . thanks to any replys from those that have done this , and what you think .

The combination of the 2 is worth about 1 - 1½ mpg. Doesn't take long for that to pay for itself and start putting money BACK into your pocket. 
And, as an added bonus, an extra handful of HP makes it to the wheels.
Doesn't make a huge noticeable difference to how they operate, though. A little maybe but not drastic.
