I have a 1999 4x4, V6, that shifts hard between 1st and 2nd gear. All other shifts, and downshifts, are smooth and fluid is red with no burnt smell. 113000 miles. Anyone ever have similar issue or have any input, to correct? You know how transmission shops can be so I don't want them telling me I need a rebuild, just because they don't really know what the source of the problem is. Thanks to all.
