How can the transmission fluid be low if there is no leak found?

Asked by Jul 20, 2012 at 02:30 PM about the 2000 Chevrolet Suburban 1500 4WD

Question type: Maintenance & Repair

We were told that we need a rebuilt/used transmission after it started losing power in second/third gear
because the transmission fluid was low. After adding more trans. fluid it still ran the same. We got
another opinion to find out that there were no leaks of trans. fluid. What causes trans. fluid to get low?

A leak, it doesn't just evaporate out of the trans as it's a sealed unit.

A leak from the trans, trans lines, trans cooler. Some have a vacuum modulator that can go bad and suck trans fluid into the motor and burn it off. Get more creative, i have a leak out of the front seal on my truck that drips onto the exhaust and burns off was it drips so i dont see it on the ground.
