trans upgrade e maxx

Hi, Im new here found this site threw traxxas I have a t and a e maxx we just converted the e maxx to the HV MAXX brushless system. we upgraded all the drive axles and put the huge swamp kong tires on it, well needless to say my son got to play with it for about 2 min. when it ripped the diffs apart. the truck had so much tourghe when he floored the throttle the truck did a complete flip and landed back on its wheels lol. anayway I orderd the maximizer diff kits with robbinson gears to take the tourghe Ive been told the trans will hold the tourghe. can someone tell me if it will for sure if not what do i need? :D ( I know that the tires have alot to do with my problem but my son loves the tires. I have to make this work for him lol!!!!)
