My shift pad is a single window. The problem has been going on for years and no one can fix it. The closest hill that will cause the problem is over 1 hour away so it is not easy to get a tech to spend about 3 hours or more to hook up a computer and take a ride with me.
To clarify what is happening: Traveling at 65mph with cruise control on, rpm about 1750. Start up the very step, long grade, about 7%min. Speed will drop quickly while rpm will drop but no shifting occurs until speed goes below 40mph. If I arrow down while speed is dropping the TX will not down shift until around speed gets to under 40 mph and 2nd kicks in. I then start to arrow up but I can't build up any speed until the grade starts to level out towards the top of the hill.
I've lived with this since most of the time the hills are no problem EXCEPT for the 7% or better grades. But, it annoys me to no end knowing that something is not right and no one can find it.
Thanks for your input
