Backed it out of the driveway to find a nice pool of fluid on my recently sealed driveway Just my luck.


I tried locating the leak but theres no dripping at this point. It seems like it lost all of the fluid. Any suggestions? Would it be worth even fixing this one?

Was it idling when you checked it? First place I would check is the dipstick tube seal or pan gasket

it was idling when i checked. What do you recommend that i run through it while testing? is there something else i can run through it during problem solving stage or should i continue to waste more ATF? I'm just frustrated as I spent $30 on the jug of fluid and it ended up all on my driveway
