Hi I'm wondering how I can lock an automatic transmission in my late father in laws 2004 pontiac sunfire as one would do with a manual transmission. We know that locking a manual is just welding a couple of the spider gears but on an auto, we aren't sure on how this could be done, the engine is a 2.2 eco if that helps any. But any ideas or anything would be appreciated as this was something he wanted done before he passed thank you in advance
