only starts in neutral.

is it a automatic or a stick? If it is a stick you have to have the clutch pedal pushed all the way down

Automatic.

If it is automatic the safty neutral switch may be bad or out of adjustment

Can it be fixed at a transmission repair shop? Is it expensive?

Thanks.

Test it first...if you've got a multi-meter...or have a reliable friend do the job...it's like two screws....but all kinda scrunched up inside the dash~

Does not have to be a trans shop a local auto repair shop should be able to do it. But like judge_ roy says if it is under the dash it is cramped

Ron....congrats...bud, you're the new expert on the 500~

Thanks roy I am no expert but the older stuff is what I used to work on. When things were alot simpler
