Overfilled transmission

[ZedsGT]

So thought I was having some tranny slip. Long story. So I got under the car and pulled the check plug, about 2 quarts came out. Not sure if kia did this on purpose or what. Kinda curious if anyone else has pulled the level plug and had the same thing

Never heard of a "check plug" (not a car guy); are you saying that nothing is supposed to come out when you literally pull the plug, if the trans has the correct amount of fluid?

This is the check plug since there's no dip stick. The center with the green is the drain plug

So, nothing is supposed to come out of there if you have the right amount of trans fluid?

It should flow out in a very tiny stream, less any .9 qts over a minute or 2.

Well, I'll be swizzled, no dipstick. I guess that tells everything about how I don't go over my engine (I've checked the oil level maybe half a dozen times in nearly three years; and never even thought, "where is that dipstick"?).

So, if you get a "very tiny stream", is that equivalent to a dipstick well into the hashmarks (full)? How would you know if your trans fluid is too low??

If its too low nothing will flow out, the fill plug is on the driver side above the oil pan.

trans fluid temperature also plays a role on expansion of the liquid, recommended check temp was btw 50-60 degrees celcius per service manual (122 - 140 F) if it was too hot while checking, then you might be draining unnecessarily. tranny issues might also be from software, there is a software reset issue in the blog I recently stumbled upon.

I wish manufacturers would start installing sight glasses on these ‘sealed’ transmissions.

If anything the temp was too cool, cool enough when it drained out it was all over my hands.

Was the engine running? The engine must be running to have the fluid distributed in the trans while checking.
Fluid settles in the pan when the engine is off, so quite a bit would come out the check plug if it was removed when the engine wasn't running.

Ah, that's pretty tricky; "raise" the vehicle but keep in on "a level ground"?? That means no half-assed garage ramps. Being "raised" and unlevel would mess with the way the ATF comes out the "inspection" hole.

ATF expands significantly when hot, which is why the level should be checked when hot. Wear gloves. I keep a pair of hot-oil-gloves in my stack of messy-oil-catch-containers.

Likely, your trans had the correct amount of oil. If you just pulled the plug and did not do the fill and check procedure, your trans fluid is likely low now.

As shown above, the trans needs to be at temp, engine running, and moved the shifter through the gears. Only then (with the engine running but in park, raised up on level ground), do you remove the fluid level plug.

Oil will drain from other areas of the trans, mainly the torque converter, when the car is off. When you turn the car on, the trans fluid pump pulls from the pan and fills the torque converter, lines, pistons, etc.

Time to go to the dealer and get this corrected. If your trans was slipping, you need to tell them this. DO NOT tell them you drained fluid out (they could use that as an excuse to void your warranty).

Likely, they will blame the slipping on the low fluid (even if this is not the cause).

Cars are not like they used to be. Read up and inform yourself.

Lol thanks dude. I have the stinger manual and the procedure.

Okay. It’s wasn’t specified in your original post so if you did it correctly, then it was overfilled.

No offense meant. It’s just a lot of people don’t now the correct procedures.

I would assume its slightly overfilled from the factory for a longer service life. Either way ill be doing 2 or 3 drain and fills with amsoil ss atf and leave it for life

Dude, people on here think buying an L bracket from Home Depot is "custom fabrication". The bar is low.
