how long does the transmission last
That depends on how well you keep it up. If the transmission fluid is changed regularly and you're not doing anything extreme, like pulling an overloaded trailer all the time or racing the thing, it will last longer than the engine. I have 210,000 miles on my transmission and have never had a problem.
Do you have two dip sticks? One for transmission and one for motor oil?
