Thanks for the email. My SL and SE both have the same transmission, I just replaced the fluid and filter in the SE and it now shifts better than the SL (no surprise). That seemed a simple operation, and as I understand that there was an upgraded B2 piston available, I thought I would try it. Maybe not. The SL sees very light summer duty (5000 km/ year), while my SE is a year round car which pulls a light trailer on weekends. Neither have high mileage (135 km on the SL and 154 on the SE). I just prefer maintenance (cheap) over repairs (expensive).
