Hello I'm new to the site and I have a 2007 Chevy Impala 3.5l with about 220,000 miles. the transmission is slipping in drive. I have been able to drive it around if I manually shift it but it is it is slipping also. I've been trying to find the easiest way to remove and replace the transmission. I'll be doing this in the parking lot of an apartment complex so I need the simplest way to remove and replace by removing the bare minimum. if anybody has experience in this I sure could use your advice thank you in advance for your help. I've seen videos of a guy pulling the engine and motor together from the top or also removing the subframe and lowering from the bottom. I don't have a lift but I have jackstands.
