Hand for Super that gave me bad vibes

[sapster]

Simple situation, I have 1.1k in the bb with ATs. Cutoff who has about 2k limps and sb completes having us both covered at around 3k, no good read on limper. Blinds =25/50

FLOP: T 67d I don't have diamonds. I lead for 150, cutoff calls (uhoh). Turn is a 4h What is my plan for the turn now that there is 450 in the pot and a bet that would protect my hand pretty much commits me.

Blinds and stack sizes please?
