Still messing with the trans. Changed all the solenoids and it has first gear ONLY if I pop off the shift linkage and manually move it in 1st . If I put it in Drive it starts off in 3rd. Move it to D3. same. Move it to D2 and it starts off in 2nd. The fiero shifter won't go to first because the stock trans only is a 3 speed.

Well here's a video if it idling with a janky autozone muffler .
