No but you have to do that to change the ATF at what 30K.It did have a good whiff of gasoline to it. No oil level drop at all nor a increase.
The belly pan is easy. Two push pins and two bolts for the access panel. I spray a bit of lithium grease onto a paper towel and clean the bolt threads while the oil is draining. Hit the hood latch as well.
Don’t tell me you took the whole belly pan off?
