Maxxim Posted September 8, 2014 Share Posted September 8, 2014 I have a 72 custom with a 400 sb - turbo 400 tranny that does not drop into passing gear - have not gone under yet to figure out why but noticed today a wire coming out of the firewall down above my gas pedal attached to black plastic piece broken off another piece attatched to top of gas pedal bracket - had to leave for work so did not investigate further yet - but it is on my mind at work so I thought I might ask if this is why my tranny does not down shift into the passing gear??

Sam (Bones) Posted September 8, 2014 Share Posted September 8, 2014 it should be an orange wire and it goes down to the drivers side of the trans, there is a sliding switch on the gas pedal Quote Link to comment Share on other sites More sharing options...
72-CLASSIC_RIDE Posted September 8, 2014 Share Posted September 8, 2014 That kick down switch signals tranny for more power based on how far the gas pedal linkage moves that spring loaded rod. As you accelerate, the gas pedal linkage moves that spring loaded rod, and when it is moved in far enough, it signals tranny for more power. Replace the switch and should be gold. Once installed, simply push spring loaded rod all the way in and let return back all the way. Switch will automatically let tranny know when more power is needed once that rod moves far enough in.
