Default Transmission runs rough only when I use my A/C or Heat.

Hey guys,

Yes its as simple as that. I have a 2004 Chevy S10 Blazer...when I run the A/C or Heat...it shifts really hard...or sometimes not at all. I have to pull over shut the A/C or heat off and start the engine up again. Other than that it shifts just fine. WTH? I don't know it its related but when It gets hot outside. 85 deg f or above...I have to wait a few minutes before I can turn my key all the way off. I can shut the engine down but the ignition won't turn all the way back. It never happens unless it is hot outside. Thanks
