My BX1830 goes through spells where it is extremely hard to get out of low range. It goes in and out of high range o.k. and goes into low range easy enough but pulling the lever out of low range is a bear. I'm afraid I'm going to break something. In the summer it began going in and out of low range very easily until I started using high range a lot while doing a project where I had to travel a distance. Hydro fluid is full and everything seems to be right. Thanks for any comments.
