trans doesn't want to downshift out of drive?
 

I new here and need a little help. When driving my car(82 berlinetta 305) and I get into drive(its a 200c by the way) and I slow down for a corner it doesn't want to downshift out of drive unless the engine drops down to around 400rpms or about 25-30mph. What could cause this, is it the TV cable or is something else wrong?
</p>

Comeon guys I need help, is this a major problem or what. Also it doesn't do it when on the 2-1 downshift so i'm wondering what the problem is. It also upshifts fine so what could it be. Please help!</p>

Try the cable, not many people here know alot about the th200c. How are the upshifts at WOT?
