I have an automatic 3 speed transmission in my 2000 jeep wrangler (4.0) . When driving down-hill it seems to speed up even when the grade is not changing. My 99 Mountaineer holds back better in first gear than my jeep. I had it diagnosed, but nothing showed up as being a problem. Has anyone else had this problem, and is there something I can do about it, other than chaning the transmission.
Thank you, Bryan R
