Not generally, no. Although it may be possible, in theory at least, for the overheating of the engine due to the head gasket leak, to cause excess heat to be transferred to your automatic transmission via the transmission oil cooler located in the radiator or simply by way of direct conductivity. This is extremely unlikely to cause the transmission any problems or even to overheat. The transmission problem is most likely a separate issue and should be treated as such.
