64 barracuda torqueFlite 904 issues

Hi. Im trying to help out my cousin with his 64 barracuda 273 push-button 904 auto . This car is a dog as it starts out in 3rd gear and won't kickdown. If I try to start out in manual low, it won't move- it acts like it's stuck in 2gears at the same time. Kickdown linkage looks fine. I'm not familiar with the push-button linkage, but I don't think that is the problem.
Any ideas ?
