i have a 2001 Mojave that the transmission clicking in first and 2nd gear. It only does it under stress, like mudding or riding in the sand really hard. Checked the sprockets and chain and are all fine. I dont not know what else to check outside the engine or even if it is the transmission. Any help would be greatly appreciated.

 

could it be the cam chain...mine does it too but i am gonna get a manual chain tensioner for it so the automatic one can't break like it did
