Actually ,when the orange "O/D" lite is on,that means the overdrive is locked out so u only have 3 speeds.When the "O/D" lite is not visible, the overdrive is on and u have the 4th speed.On top of the tranny there is a harness with 3 c neutral safety switch connector,the kickdown solenoid connector, and the overdrive cancel connector.Make sure these are clean and free from grease and/or corrosion and are properly connected BEFORE u go to the trouble and expense of replacing the solenoids--they aint cheap.Lol.There is a kickdown switch behind the accelerator linkage. Be sure it is it is properly adjusted--the switch should just touch the stopper on the firewall when the throttle is fully depressed. You can also check that switch with an ommeter to be sure it is good. Hope this helps and Good luck.bj
