I am swapping out new used engine for my shot out engine in my 1991 toyota 4Runner. my question is, which is better to take out old engine with transmisssion attached or to leave transmission in vehicle. part of what i am wondering is it easier to reattach and align transmission on engine going in out of the vehicle or is it not too much trouble inside the vehicle?

With economy being good or bad we have to save money where we can, and you can save hundreds and possibly even thousands of dollars by getting used engines or used transmissions to repair your car or truck. Some of the people believe that used engines or transmissions fails to match up with the performance given by new ones. However, its not true few weeks back I have purchased a used car engine Automotix and now my car is running very smoothly without any inconvenience.

Swapping an engine need a lots technical experience in this field, as doing it yourself could be a challenge. I would suggest you hire the services of a certified technician while doing this and have them swap or replace your engine.
