Hello all. I have a 87 rx7 with a lt1 and a 4l60e behind it. Car runs and all. I have park,reverse,1st and 2nd. I know the trans is good. My question for y'all that did this swap is, how do I get this trans to shift to 3rd and 4th? My speedometer is not hooked up on the dash since it's cable and trans is electric, the tach also doesn't work on the dash. Is there something extra that I have to buy for this trans to work? Everything is wired in and the 2 plugs are plugged in on the trans.
thank your!
