What would happen if I put transmission oil in the motor oil?

And vice versa...


Damn, I'm screwed...I was trying to save some money up but the did that...What I do now? I ran the car to test it out and drove it for an hour and now it sounds really bad.What would happen if I put transmission oil in the motor oil?
I'm a mechanic, and own my own shop, so I don't think you have killed your car just yet anyway. Transmission fluid is very high detergent, and will clean the engine so much that it will make all kinds of noise due to the fluid not being thick enough to lubricate the engine properly. Drain it all out, and put in some 10w 40w Casterol, and it should save the engine. Change to a new filter also.


As for the transmission; You have got to get all of that out of there that you can, and I mean all that you can. Drain it by removing the pan. With the front end as high as you can get it, and the pan off, let it sit and drain for about 8-10 hours, and most of it will come out. Don't replace the filter in the transmission just yet. Put the pan back on, and fill with 5-6 quarts of transmission fluid, run the engine for about 3-5 minutes, and repeat the procedure. After doing this twice, replace the filter in the transmissison, install a new pan gasket along with a new filter, and fill the transmission back to normal. Add 4 -5 quarts of fluid with the rear wheels off the ground so you can run it. Bring the engine up to normal operating temperature, run it through the gears, put it in park and check the fluid level several times with the car on a lever surface. Make sure the wheels have stopped turning befoe you put it in park, or it will break the park right out of the transmission. Get a bottle of stuff called Lube-Gard from Advance Auto Parts, and make sure its the stuff in the white bottle. Add one bottle to the transmission, and top off the transmission with fluid. Don't over fill the transmission. Check it hot, on level ground, and check it many times. When you remove the dipstick it will drag fluid up the tube, and it will be hard to see, but it will have two different readings on the stick if you look at both sides of the stick. Go by the lowest reading on the stick. Let it run for a good 30 minutes, and check it again. If you over fill it, you can always get a hand pump and pull some back out the fill tube. It's important that its not over filled. If you will do this, it should fix your car. You haven't damaged it as some people want you to believe, but you really didn't do it any favors either. I've seen engines that had a fuel pump go bad, and fill the engine with gasoline, and it sounded like everything in it was going to come out, but once the gas was removed and the oil %26amp; filter were changed, the engine was fine. I have been there and done that. The transmission is probably not hurt either, it just might not shift gears until you get it out, and will have a smell about it because the transmission will get real hot with that thick of oil in it. It will be alright....! I own a transmission shop, and I don't think you have done much damage to it. Good Luck!!!What would happen if I put transmission oil in the motor oil?
Oops....You wanted to buy a new car anyway, huh?
Do not drive it!!! Damage probably already done, Motor oil is designed to reduce friction and heat to very high heat levels. Transmission oil is designed for similiar activity, just not on the same scale. Take it to a reputable mechanic and have him check to see if you have scored the pistons or created any internal damge. I would have it towed, do not drive. Must drain out of both engine and transmission, Then need to have both flushed to remove any residue. Could be a costly mistake....
Pretty much what everybody said. Although your engine may not be as bad as the tranny





Engine: The engine needs lubrication. Transmission oil will provide lubrication but at a very low viscosity. There are also additives in Transmission fluid that are not necessarily good for your engine. Depending upon how hot it got you may be ok. You will need to drain out the Transmission oil (and replace the filter) then run the engine (do NOT engage the transmission) for a while. If it is making that bad noise then don't bother.. shut it down and call a mechanic. If it sounds ok.. take a deep breath you are halfway home (but the ride is not going to be pleasant). Shut the car down and change the oil and filter again to get the last bit of trans. oil out.





ok.. so much for the GOOD part that noise had to come from somewhere.





Transmissions need a thin oil.. (the red stuff). But engine oil has additives in it too.. They make the oil get thicker as it heats up (viscosity is usually shown as 10-30w which means it starts out thin (10 weight) and gets thick (30 or 3 TIMES THICKER) when it warms up.





Guess what.... thick oil will not circulate in the transmission so it is likely toast.





With your engine now running (I hope) call up a transmission place and get the car towed. They will need to drop the inspection pan, drain the oil out and tell you what the damage is.





not a very nice christmas present was it.





sorry





Remeber the red oil goes into the transmission hole (you must have had to WORK to get oil into that little thing).
You blew the engine up. Plain and simple. You're going to have to replace the whole engine. That usually runs anywhere from 2000.00 to 5000.00
Not good, I think the damage to the engine could be greater, the transmission may have gotten a little hot but it was still lubricated.
I would guess calling a transmission repair place would be a good idea. Tell them what happened and ask what can be done to correct it.
The bigger problem in motor oil in transmission. Take it to a full service garage where they can drain both. If you don't drive more than a few dozen miles you shoiuld be OK.
first off, dont drive the vehicle is the first correct step.what your going to want to do is to drain all the fluids out of the tranny,and the engine,leave the drain plugs off over night to allow as much as possible to drain from them. next what youll have to do is replace the filters.the run the correct fluid thruogh the engine and transmission to flush out the contaminents.then drain again,and refill with the correct fluids.
