Can anyone help me? I have a 2013 mustang gt with the 6r80 auto and I believe it has a very VERY slow transmission pan gasket leak. I had replaced it just 2 days ago with an OEM gasket as part of doing a regular fluid change. Everything was torqued down to spec, 106 inch pounds.
Today I had it on a lift at a shop getting some other work done and we happened to observe what was maybe HALF of an eye dropper sized drop of fluid seeping through just one corner of where the pan meets the gasket. (This was observed while car was running in park on the lift and at operating temp).
Nothing was dripping, and just to give you all an idea of how little fluid actually appeared to be “leaking,” it was about a pencil thin line of fluid about half an inch long on just one corner of the gasket. Literally it was like someone took a regular ballpoint red pen and drew a line half an inch long, that’s how little fluid there actually was. It would probably not be visible if you were looking at it from more than a foot away.
I do know the very small amount of fluid we saw was a leak and not residual from servicing the trans 2 days ago, because when I replaced the gasket and reinstalled the pan and refilled with fluid I wiped everything off very well immediately after finishing the job and saw absolutely no red anywhere on the pan or gasket
Mechanic told me to just leave it alone, and given its current state with the leak being that small I agree it’s probably not worth messing with plus I really don’t want to do this job again or have to pay someone else to do it…
However I’m a little wary of driving it knowing it has any kind of transmission leak even a tiny one since this transmission doesn’t have a under the hood dipstick, so checking and monitoring the level is a pain in the ass!
My question is this: I have an obd scan tool that tells me trans temps, would it be feasible to monitor the level this way? ie if the leak got worse causing the fluid to get too low, would the temps will be noticeably hotter, then I’d know the leak had gotten larger and I’d have it get fixed? The shop i took it to verified the fluid level was correct, I then drove the car for over an hour and the hottest the trans ever got was 188. So in theory if the trans fluid became too low wouldn’t it start reading hotter and I would know I’d have to add fluid and get the transmission re serviced. But like I said earlier I don’t want to unnecessarily redo this job if I can’t help it
And also I just can’t be asked to get out my jack, jackstands, run the car for 30 min to get trans up to temp and then check the level next to the burning hot cat every single time i want to check the level. Using the scanner would definitely save me a lot of headache if this was feasible. Anyone have any input? Should I just not think about it, monitor temps using scanner or just suck it up and re do the entire job?
