You're replacing your automatic transmission with a manual transmission?
If you're wanting to keep your automatic transmission but want to replace its shifter for one that looks like it's for a manual transmission, that won't be as easy as you might hope. The T-handle is there since you need to be able to use its push button to unlock the shifter so you can shift out of Park. That wouldn't be possible with a standard manual transmission shifter, at least it wouldn't be an easy thing to get working. It's likely you can find an aftermarket shift knob that would make it look more like a manual transmission.
