I am looking to remove/replace my transmission and need a DIY video or at least guide on what the process. I find similar processes, but I don't know if the process is universal or applies to the specific car you're doing. I just want to be sure I am removing the right things to only take out and replace transmission.

Hi,

The replacement of this transmission is a little difficult. It will require the engine to be supported and the subframe will need to be removed. Additionally, once the new transmission is installed, the transmission control module (TCM) will need programmed.

I attached the directions below specific to this vehicle. Take a look through them and let me know if you have questions or if I can help in any way.

Take care,

Joe
