Hello.
I have a 91 dodge dynasty which is in a limp mode. I replaced three speed sensors and rebuilt servo pack. I can't find a transmission computer. I read somewhere that it is a long blue connector but for the life of me I can not find it.
Also what scanner tool do I have to use to read the codes off it ?

Will this transmission stay in a limp mode untill codes are erased or taking battery off for a 20 minutes is enough to erase trouble codes?

Check the Electronic Automatic Transmission Controller On right fender panel, in front of strut tower.
