Drove with -1.4 Qts. Tranmission Fluid

Did a drop and filter replacement just recently. Manual I had said add 6 qts., turns out I was supposed to add 7.4.

Just curious what the odds of damage are after driving 100 miles. I added the remaining fluid and now at the proper fill line.


I did check the levels when I initially did it, but since I had to do it on an incline im guessing the results were skewed.

If you did not notice any change in how the transmision shifted or operated than there likely is no damage. Just like you can run an engine a quart or more or heck sometimes I've literally drained a shot glass of oil and they ran fine before and after. The problem is when it gets low enough that the trans can no longer suck any fluid. if theres no fluid theres no pressure and the trans slips. That is when there can be a problem!

Like I always tell the new guys at work, "it takes as much as it needs to read full on the dipstick!"
