I too am having this problem. At first it was just e beeping and the message, the tranny was going out and I had it re built. Now at the VIC is says "LO" and drives fine but turns like it is in low. is this maybe a switch problem , a vacuum problem or a fluid problem? I love this jeep and would love to get it fixed for peace of mind but also so I do not cause more problems by letting it go.
Mine is a 95 Grand LTD auto tranny
