I came to the decsion that i am going to try to make this 4l80e work. my question is i no 1st and 2nd gear shift off line pressure 3rd and 4th are electronic. I can wire 3rd 4th and the torque converter to 3 differnt tongue switchs. But i was going to see instead of having all kinds of tongue switchs 1 for my train horns 1 for my system then 3 for my tranny can i just buy a dsp5 switch and wire the tranny in to the dsp5 switch. If so the only thing i can see that i will have to wire into a tg switch will be my torque converter
