I own the slowest h/c/i mustang in the world

I have a 3200 rpm stall. I got it dynotuned today and a chip burned.... 185hp and 230tq.(mustang dyno) LOL. It just keeps getting worse. There is a really bad vibration in 3rd and overdrive and the guy who did my chip thinks the tranny is going. I thought maybe itwas just the driveshaft but only does it when your on the gas so he said it has to be the tranny.. How much power could a bad aod tranny suck up? The car ran fine besides that and we got the a/f ratio set great and he got it to idle, it feels a lot smoother and more power now but that still seems way 2 low for my mods.
 
5hp 22ftlb, the main thing for me is it wouldn't idle it would surge everywhere, it idles beautifully now and even though it only makes 5 more hp i swear it feels quite a bit faster and comes on a lot smoother. Anyone know if a bad aod would suck up power and an estimate of how much?
