Try coating your dishes with poly-D-lysine (100ug/ml reusable solution in sterile water).  
Just add the solution, swish on the dish, and aspirate and let air dry briefly.
You can get the stuff gamma-irradiated from Sigma.

I don't think your problem is your transfection technique, rather the cells are very
difficult to keep on a dish, particularly at temperatures < 37C.
