I don't  remember for certain but some time (years) ago there was talk
about NOT  changing the fluid in an auto tranny because it would have a negative
effect.  Can someone  post the latest word on when or if to change the AT
fluid. I  have a auto 85 Westy with 86K and I don't think the trans has ever
been  serviced. Thanks for any  info.
