Subject: Re: 1981 Lock up torque converter by CentralCoaster on 2008/9/20 0:00:09 Why not just use a vacuum switch? It seems like you'd be hitting that switch back and forth all the live long day. With it on, you may find the converter locking up unexpectedly as soon as you hit that speed (depending on your pressure switch), and making the car lug and sputter bigtime. I used p/n GM 14014519 for the vacuum switch, and 12101914 for the connector. If you wire this inline with your brake cancel switch, and run it to a ported vacuum source, it will unlock the converter under heavy throttle, and also during coasting. Otherwise, you pretty much always want the TCC locked up in 4th (or 3rd for a th350). But that part is done within the transmission, and I don't know exactly what pressure switches and wiring setup is needed for that. |
