AC Issue / Transmission Jerky

[NetLexus]

2008 Lexus 460L Executive model, stopped blowing cold air suddenly earlier today. For the past week or so, it seemed like the car will get warm when not in motion say at a traffic light even when the AC was set to 65 deg but when in motion the AC would seem okay. Called my routine mechanic he said it may be a leak or an electrical problem. Any insights on this. 

Another thing I noticed for a few minutes just before the AC went out, the transmission seemed a little jerky and lagging, as in I pushed the accelerator but the car wouldn't respond. Not sure if there is a connection, but any insight is appreciated. Thanks!

Could be Air Cond related...as in the compressor being faulty and dragging the engine revs down.

Definitely worth letting your mechanic check it over as soon as possible.
