Pension plan payment deductions if I earn too much income.

Next year i am transitioning into retirement. I have two pension plans and Soc Sec, and I expect to still earn income over the next few years. I understand that if I start taking SS the amount can be significantly reduced by my regular earnings, Is that also true with the Pension plans? If I hold off taking SS for a few years, but take the Pension benefits, will I still be penalized if I make regular income above some threshold?
