Hello to all. So ive added a few mods on my Trans Am and lately my car wont shift; will just ovr rev. My power seems gone under hard/firm driving like when my clutch went out on my old Z/28 and i smell burnt ATF fluid when the tranny heats up.

I was thinking, could my added mods have damaged my tranny? Since i have never tuned my car or changed the shift tables. I don't think i changed the setup substantially that it would need a tune but i'am still skeptical. It is a straight shot from the air filter to the intake. Is a tune necessary for what mods i have? Can changing the shift tables help me out hear or dose the burnt smell of tranny fluid mean i need a re-build?

Can anyone point me in the right direction; i would appriciate it greatly, Thank you.

Any SES Lights? Codes Thrown? Have you change tires/wheels size?

I cant see that your new mods could have caused the issue. Probably just a coincidence that the issue started around the time you threw a few mods on. Get it scanned for any stored pcm codes at a local parts store and if there is a code that was thrown post it up here for us.
