@BAAK;
Gear locks restrict the movement of the gear lever. They are not attached to the gear box. Therefore they will not have any effect on the gear box,whether manual or auto transmission.
Nonetheless,I find all these anti-theft devices a complete waste of money!!!
My car has an alarm/immobiliser. After several years of use,the remote control broke off from the key so I keep it [the remote] in my pocket while driving.
Then One day thugs attacked me on the road; threw me out and drove off with the car. I was left on the road-side [thank God] but I never remembered to use the immobiliser as the thugs drove away!!!!
If you ask me,all these gadgets do not make you car any safer and they cost more than you will save in insurance costs [premiums and / or theft excesses].
And the gear lock is an ugly thing in the driver's cabin!!!!
