Havent posted in quite a while but its good to finally have a question! alright so I just today got a freshly rebuilt 2004r but without the torque converter, TV cable, anything. im definitely going to run the lock-up as im switching from cast iron powerglide to overdrive purely for the lower rpms, especially on the interstate i take every weekend (and the trip to Bowling Green this year!), but reading the forums, i understand that there is some contention as to whether to have an automatic lock-up in 4th gear, or have a manual switch to control it. or to have the breaks disengage the lockup? and a vacuum switch from the carb to disengage it when the engine is at wide open throttle? so im very confused, and would like to know whats the best way to go about this. I have a factory 283 powerpack, factory 3.36 rear end and gears. I dont race but i like a little giddyup every now and then. Id prefer to not have yet another switch cluttering my dash, but ill do what i have to.
