Tranny Going bad

I drive a 1988 camaro with a th700 -r4 tranny. Today I was at a red light and started driving off and it shifted from 1st to 2nd fine but did not shift into drive or overdrive. Any suggestions???

3-4 clutch packs might be toast

That or the servo.

However there seems to be a rash of catalytic converter failures lately, any other performance issues?
