What happens when you put oil where the transmission go

Perhaps this is transmission fluid. If you haven't serviced the transmission recently, the fluid may have lost its typical different color from motor oil and turned black. This might be especially true if the car had been driven hard or was towing something. The transmission has an oil line that connects to a cooler next to the radiator. If it's all dirty and black, it might be hard to tell a difference at first. Check this to see if this is the issue. This happens more often than one might think.

1- Transmission oil level very low (Check Transmission oil level)
2-Shifter cable broken
Look at the transmission cable shifter when you move into gears if it changes position at the transmission (ENGINE OFF).

Hope it helps.

Why would you risk your thousands dollars in repairs. Just use the correct fluids for the correct system. I hope you would need put antifreeze in your engine oil. Why would you put engine oil in the transmissions. They are totally different lubricants and designed in different ways to extend the life of you parts. If you don't know what to use. Call the dealer or look in the owners manual. Sometimes cars need tranyfluid for power steering fluid but again that's what it calls for. Engine oil will destroy a trany might not be today or next week but it will fail and that's bad for the pocket

Not much as long as you didn't drive it very far.
Transmission fluid has lubricating properties like motor oil but it is much thinner.
All you need to do is drain it and change the filter.

How much transmission fluid did you add? In the old days adding a quart of tranny fluid to the engine oil was used to loosen valve springs etc...only running a day or 2 then draining completely..and refilling with quality engine oil...If you only added a quart...you need to drain all the oil as if doing a regular oil change...do change the filter too...you should be just fine...don't put this off.

when you drive a transmission on low oil transmission clutches pay the price have on the other hand when the torke converter fails there is no power try the oil and filter first see what happens or take it to a profesional good luck

Lack of oil from the sound of it ,When checking the auto oil level start engine put handbrake on hard ,couple of bricks behind the drive wheels then drop into reverse ,now check the oil level on the autobox dipstick .If a modern vehicle with no dip stick then dealer only job to check the level

If the transmission is over full this will happen, if the transmission overheats this will happen, check the level carefully by the instructions on the dipstick to ensure that it is filled properly. There is also a vent on the top of the transmission, a favorite home place for dirt wasps, make sure it is clean. If you think this problem is over heating, check the oil cooler for obstructions pinched lines etc., I put an external oil cooler on my transmission to provide more cooling capacity, though it is not truely neccessary. Hope this helps, let me know.

Engine and transmission are completely sealed off from one another. No way changing the engine oil will affect the transmission unless a brain sturgeon put engine oil into the transmission by mistake. If you did the service, you know that didn't happen.

Yes the transmission fluid goes in the location of the dipstick. As for the yellow "oil", if you just recently got the car maybe the previous owner put engine oil in the tranny fluid receptor instead of the engine...it's been known to happen. As far as I know, tranny fluid should be red, even if water gets into it, it's still a pinkish color. Maybe better to drain it and replace it. Good luck.
