1998 GS400. Even with the pressure dial all the way up, I can barely feel the gear changes at any level of throttle. I drove two other GS4s which likely didn’t have the pressure dial turned up, and they change gears much more solidly. My fluid is all fresh, but when I first had the car is was further on the brown side than I like. It hasn’t gotten any worse over two years of somewhat aggressive driving. But what are the odds a filter change would fix it? I’m thinking if there’s enough worn crap in the filter to kill it, I may as well just get a junkyard tranny. I’m kind of strapped for cash at the moment so any sage advice as to the most cost-effective fix is greatly needed.
