in this short rendition of a video I intended to post 2 years ago. you will learn the basics of how some transmissions use multiple shift solenoids to control what gear the transmission is in and how you can gain control of those solenoids. I use the 4R70W in a '95 F150, but this is applicable to many transmissions. you will need to look up a rebuild/repair manual for your specific transmission. that will have all the info to know if yours is compatible and how to wire up the shifter for each gear.
