Thank you Otto and the other gentleman. You were exactly right, I found a white wire completely broken off after hitting the sharp edge on the plastic wire holder mounted to trunk hinge (what was supposed to protect it.) every time the trunk was opened/closed. I stripped back the two ends of white wire and connected together, my car is back to normal now. I wrapped enough tape to make it somewhat solid. I suggest everyone should inspect this area to avoid problem.

Recently this started to happen on my 93 LS400 at about 270k. When driving, if I hit the brake paddle, reverse light comes on and overdrive goes off. Appears to be a wiring short from brake to reverse switch. Reverse indication might be kicking off the over drive which may be a function of the computer. Anyone knows anything about this kind of problem? For now, I am driving with overdrive off in local traffic etc. I am hoping to know better before I go for repairs so as to save some costs. Thanks.
