The manual transmission oil, or gear box oil can't last forever. It is a good idea to replace every 60K miles with a new one. Just as
with motor oil, and oil change is cheap insurance. Buy synthetic oil if you can.
The manual transmission oil change is a simple procedure, but can complicated and creates costly problems.
First remove the filling bolt. In some cases this is siezed, If the heating doesn't help, you don't want a stripped filler bolt, with an empty transmission. Use WD-40 and do not use extensive force.
If the bolt still won't budge. Stop. Lower the car and visit a shop
for service.
After removing the filler bolt (upper), then remove the drain bolt at the bottom.
Replace the drain bolt, with a new one, normally has a magnet, and thread it by hand after with a wrench.
Fill the gearbox with oil using a gear oil / lube pump. Replace the filling bolt and process same as with draining bolt.
If you will change the gear box oil every 60K miles this is the best insurance for your manual transmission. DO NOT FORGET TO REPLACE FILLING AND DRAINING BOLTS WITH NEW ONE.
In rare cases a rusty bolt is siezed, almost rust welded in the transmission housing, so the transmission must be removed and taken to
a machine shop.
