Fairly easy with an impact gun, theres three nuts underneath, two accessed through holes in the subframe. Top 19mm nut i used a wrench spanner as could not get a socket on it. Just gave it the ol "thats not going anywhere" torque 🙂
Took me multiple tiny turns with an offset ring spanner to get that bolt out once the trans was jacked up, fortunately theres not much torque on those bolts so breaking them loose isn't a problem. Happy anyway to have killed two birds with one stone.... The shift quality has improved markedly, next time I do an oil change I'll drop the fluid again and do another refill.
