Anything is possible, but the cost may be an issue. The idea that you want to change to a manual transmission leaves a lot of questions unanswered. The powertrain control module in your vehicle is designed for an automatic transmission. It's designed to work in conjunction with the transmission control module for shifting, starting, and basically anything the transmission does. If the transmission is replaced with a manual, I feel (not 100% sure) that there will be problems with the PCM running the engine and other controls.
That leads to the next issue, what wiring needs to be replaced or changed, do you need a different PCM, and so on. Also, you need to keep in mind that you will need all the accessories that work with a manual transmission. You will have to install a different mount for a clutch pedal, the firewall will need to be modified and a clutch master cylinder will need to be installed, the piping between the clutch mc and a slave cylinder will need to be installed, and the trans will require different mounts, and so on.
I can nearly guarantee you that I'm missing things, but those are going to be the biggest obstacles. The cost of this is going to be very high. If it was mine, I would likely just purchase one with a manual installed from the factory and sell what you have. But that's your call.
I guess overall, can you do it? The answer is yes. However, the cost and unknowns would likely cause me to come up with a different plan.
I hope this makes sense. I don't want to just tell you one can be installed with no issues. If the vehicle was made in the 1970s, it wouldn't be nearly as difficult. LOL Things have changed over the years.
Let me know if there is anything I can do to help or if you simply have other questions.
