Is it possible to change Manual Transmission to Automatic?

Sure, it's possible to swap but there is a lot of work involved. On top of changing radiators, tranny mounts, shifters and linkage, getting rid of clutch pedal, findind right driveshaft, tranny lines to radiator
you will have to change the flywheel and torque converter. These are the things I can think of off the top of my head right now while waiting for my morning coffee to kick in but you get the ideaof what you are looking at here, I think. Like I said, a lot of work but wouldn't it be nice to quit shifting so dang much? It can be done if you want to put out that much effort and$$$. :
