Symptoms of Too Much Transmission Fluid (How Much Transmission Fluid is Too Much?) 

The shops changing the fluid are often the people overfilling it……

1. Overheat: The more fluid, the less heat. 2. Leaking seals: The oil pump generates pressure that goes to the valve body and returns to the oil pan. There is no pressure inside the oil pan; otherwise, it would leak at the weakest point, which is the oil dipstick. 3. Gear changes: Gear changes depend on various factors, such as correct oil pressure, accurate sensor readings, and functioning solenoids. The valve body is the heart of the transmission, and all the oil that enters it to perform work comes directly from the oil pump, not the oil pan. 4. I have 20+ years of experience in AT, and I have never seen any issue with driving a vehicle overfilled with oil. This applies to both engine oil and transmission oil. when I say overfilled, I mean something about 2 ou 3 extra L

My accord was way overfilled, just siphoned majority of the fluid added a new quart of Valvoline Maxlife plus some lube gard. Works great.

I can't get a clean read on the dipstick of my '06 F-150. It seems like fluid is showing up on the edges of the dipstick for several inches above the hash marks. I siphoned out about a quart, then nothing showed on the dipstick at all. I put back half a quart, and it's back to showing fluid all over the dipstick. There is no clear level line.

If you don't have a syphon, a water bottle spray nozzle can get out the extra fluid and even pull the dirty fluid settled in the bottom

If you don't have a dipstick, checking the fluid will require you to get under the car and remove the drain plug while the car is running and being a certain temperature

Will it cause lack of excelerition

Mine is confusing, the level cold is high,warm it barely registers on my dipstick

its too much ...im having the same issue .... i last remember adding 1qrt and after awhile i had the issue, iwill drain the amount out perhaps do it all over again minus my 1qrt thats my theory i will try this,my fluid isfresh and red too so thats my approach? thoughts ? please and thank you (2006 g35 coupe)

I hava a 4l60E AT and I need to know how much ATF should be in the pan when the trans is COLD. Anyone know? I put the trans back in after an engine swap with whatever fluid was in the converter. That's the reason I am asking, I don't know how much was in the converter because it always stayed in place and I just raised it to the bell housing, put the bolts in and worked backwared to the rear axle. Is there a SAFE amount to put in the pan?

Ive got a c6 that didnt have a dipstick with it. So i used the one that i had on the last one... but the tube was shorter... so im worried. A few weeks ago it was leaking... so i puy in some molly. Well, come to find the leak was in the yoke tha cracked. It stopped shifting automatically down into first... it will manually.. and it sounds like it is trying to. Any tips?

Just bought a car. When I drive it first thing in the morning it shifts perfect, but after driving it for 5 or 10 minutes it likes to ram into 2nd & 3rd gear. What's this about?

Mine vibrates when u give it gas stops when u let off will to much fluid do this??

Our 2009 Nissan Sentra has a manual transmission. It started to give some jerks right at the beginning of driving (when you start to drive in the morning). It happens in the 1st gear when you just release the clutch pedal, jerks somewhere in the area of front passenger wheel, like that wheel can't rotate for a second or smth, then goes normally. If you bring it to stop and then start to drive all that repeats. The problem continues for ~10 min. After that no jerking after stops. Is it smth w/brakes on the FP side or it is smth w/transmission (like low on transmission fluid)? I've recently went over a curb w/that particular side (PS), but I don't remember if the problem started right after that or later. I would appreciate any opinions on this matter. Thank you for a great and informative film.

Mine is too high cold to low or just right on hot but wont shift past 1st gear

My 2015 chevy cruze lt gets stuck in gear when accelerating but only after a few hours of driving. Could this be too much or too little fluid?

How to improve atf gear for D waiting symtom(Atf gear,no gear box ecu)

when I do allot of stop and go on a hot day and my thermostat climbs a little higher then normal I've noticed my vehicle won't accelerate until maybe I hit 10 to 15 mph then it will drive normal. My RPMs don't go up even though the gas petal is floored so it's not slipping. It basically acts like if your in a standard transmission car and u try to take off in 2nd or 3rd no matter how much gas u give it, it won't accelerate until it hits the proper speed. Could this be an issue with transmission fluid being to high or something else wrong with the transmission?

Had a blazer for a few months. Checked the fluid when I got it and the trans fluid was astronomically high, but didn’t have a way to drain it. It’s been fine for about 6 months, and all of a sudden today it just stopped shifting completely. No reverse, nothing. Turned it off for a minute and turned it back on and drove home slow, but now it’s fine again. I’m gravity draining it now through the dipstick, but would this be a sign of a bad trans, or too much fluid? I know I need new fluid as this fluids darker than normal, but I’m worried I’ll need a new trans and I don’t have the money for it rn
