Hey everyone, noob here..im not an expert on cars(obviously) but ive always done the oil change on all of the cars i had, today while doing an oil change,i accidentally drained about 2.5 quarts of transmission fluid off my is250 thinking it was the engine oil pan(i know, im an idiot), put the plug back in, changed the oil filter, then poured the oil in the engine then drove about 4-6 miles, at stop i pressed the gas and the car revved from 0 to 3000rpm then would drop down to 2000rpm in a beat, did that about 4 times thinking it was normal, then boom check vsc, engine light, and the traction light came on. so basically i had 13 quartz combination of the new and the old engine oil and 2.5 less transmission fluid when i drove it..My question is, do you think i did any damage to my car(engine, transmission)?

Im gonna have the car towed to the dealership by monday so they can flush the transmission and put some fluid in it, but i just wanna know, if there's anyone out there that did the same mistake i did, or know about this stuff..thanks, id appreciate anyone that could help

 

It is entirely possible that you fried the transmission. You basically starved the trans of oil. If you tried to accelerate and the engine revved and the car didnt move, thats definitely not a good sign. Overfilling oil by that much can do damage as well. You wont know til you take it to the dealer... possible that it didnt do any damage, and possible that it did a lot of damage.

 

damn sorry to hear that, hope you didnt blow up the engine gasket for have too much oil, plus the crankshaft have to work harder to get through all that extra oil thats probably why the engine reacted that way.. Drain some oout and see what happen. I could be wrong..

 

This has got to be a troll. Are you saying you didn't even drain the oil and just added more? And you're saying you always do oil changes on your cars?

 

WTF..............mess up on a honda or toyota not a LEXUS

 

I think he is already pretty mad and frustrated from what happened,(I would) give him some tips/advices if we can.

 

When i was doing the change oil i thought the transmission fluid pan was the oil pan, it looks similar to the is350 oil pan thats why i thought i was the right one..i wasnt try to mess woth it, i just made a mistake..thanks tho

 

I'm not one to judge, and especially being relatively new here as well, but he stated he performs oil changes himself on all his cars, yet later he says when he drove it around it had 13 "quartz" of oil. Not to mention it's his first and only post as someone who has freshly registered. Perhaps other forums have jaded me, but it's hard to take the thread starter seriously or even consider this is a serious thread.

 

Simple question: did you or did you not drain any oil from the car before attempting to fill it up with new oil?

 

ok the situation already sucks as it is no need to make fun of the guy anymore. moving on.... at this point you should probably just have it towed to a mechanic or the stealership to have it checked. I wouldnt even drive it before you do anymore damage. good luck

 

I drained the transmission fluid pan thinking it was the oil pan..i thought i was draining the motor oil but instead i drained the transmissionfluid, now thnking all of the old motor oil was out, i poured about 6.7 quartz of new oil, so if i didnt drain the old motor oil which i estimated is 6.7 quartz i so thats around 13 quartz, aint it?..i apologize im a newbie here..i just need a little help

 

Thanks appreciate it

 

I think he drained the transmission oil a little, then without draining the engine oil he added another 6/7quarts. but ur right about the statement that he made " but ive always done the oil change on all of the cars i had..."

 

Not sure how much damage you did to the transmission considering you wont get much out opening up the drain bolt but the overfill of oil would worry me. I would expect the gaskets and seals to burst quickly with all that extra pressure from the excess oil.

I didn't even know it was possibly to overfill by that much without it being very apparent!

 

You didn't check the dipstick?
