Only starts in neutral

Your tranny linkage is just a hair out of adjustment.
Get the car up on jack stands and crawl under the driver seat.
Have somebody run the tranny thru the gears and then put it back in park while you watch the linkage move.
The lever and rod attached to the tranny will move to the rear of the car as the tranny goes from drive, thru neutral, reverse and into park.
When it hits park.,loosen the adjuster bolt on the swivel assembly and move it forward (towards the engine) about 1/8th of an inch.
Tighten the bolt and try to start it.



Thx Dave, This worked perfectly!!!
