I took my Grenadier to fishing camp 2 weeks ago, The camp is on a dirt road and you have to drive through a creek (shin deep ) a couple times, In the process of driving on dirt road, a stick (as thick as your pointer finger) managed to poke a hole a the transmission dish (according to the service manager) Does this sound correct? I'm kinda at a loss of words. Has anyone had any issues with the transmission dish?
