Please have a look at this article. About half way down there is a key to the 10 flashes the "Power" light does when you switch on. This might help with pinpointing an electronic (not mechanical) fault. http://www.btinternet.com/~d.brooks1/boxinfo.htm There is also another diagnostic procedure that I can't find, but Pete (who wrote the article) knows. It's a sort of masonic-handshake-standard-of-complexity sequence of shift stick movements that does something or other. However my memory is hazy, and it may have just been directions for how to weave a fishing net. Finally, is there anything up in the temperature sensor circuit that makes it think it's permanently cold? O/D is disabled for a few minutes after start-up so that it can't be engaged until the ATF is up to operating temperature. : Problem is, overdrive does not work. It goes through the first three gears just fine, but overdrive does not work. The button works on the automatic shifter and the light comes on on the dashboard when overdrive is off. : What is the problem? I am dumbfounded.
Bad luck. You have my respect for doing that job. (And you have probably thought of / know about the following...)
: I just installed an automatic transmission from a 1993 Maxima into my 1990 model which is automatic too, which has a 1994 engine, which I recently installed, too.
