... if your car is a base or an S.
The transmissions are different.
Sometimes you may have a failing shift cable or bad linkage which doesn't allow the gear to be fully engaged and it tends to pop out.
If it's determined that the tranny's gears, synchros, selectors, etc. are worn and/or damaged, many times it's more economical to just replace the complete transmission assembly rather than trying to open it and fix it.
A used transmission with s warranty can be easily found at a decent price. All you'd need to do is flush it and service it when installing.
Once you pull the transmission, clutch and flywheel, most of the work to install the DOF has been done.
I would put it in.
Good luck.
Happy Boxstering
