Ever since I bought my car the OD hasn't worked. The guy before me installed a kickdown lockout out switch for the 700R4 trans. He didn't seem to bright to begin with could this have caused my OD not to work. There were about 3 times where I had started my car up from sitting overnight and just left. I guess while everything was still cold it seemed like my OD kicked in until the car warmed up. Usually going 65 i push 2500rpm well those 3 times my rpm was at 1750. any suggestions.
