A good way to avoid putting stress on the transmission is to select a lower gear and keep it there if the transmission keeps shifting up and down. Not sure which engine/rear axle ratio you have but the engine will probably be comfortable in the 2200 rpm range with the least amount of transmission gear hunting.
On steep hills, shift down and let the engine rev above 3000 rpm to get the torque range you need for climbing, and do the same for descending those hills to get the engine compression braking you will want.
You will learn to use the transmission shifter to get the best performance and least amount of strain.
