The transmission is the same
The transmission is the same.
I am not an expert but the engine has absolutely, positively, nothing to do with 4wd. It is the transmission. In fact, it is really a transfer case that controls the 4wd.
it would be much cheaper to buy a 4x4
The center shaft in a 2-wheel drive transmission is shorter then a 4-wheel drive transmission because the 2-wheel drive does not have a transfur case on the back of it. NOW, You can take the center shaft out of the 4-wheel drive trans. and install it in the 2-wheel trans. and it will now work in the 4-wheel drive vehicle. To change the center shaft requires both transmission to be taken all the way apart.
