Over-full is over-full. Just make darn sure the vehicle is parked on a level surface and you are checking it according to the instructions in the owner's manual. Otherwise you will get a false reading. IMO, if it is over-full drain some until it is at the full mark. Now, it might be fine if it is just slightly over-full but why take a chance? Replacing transmission seals is very expensive.
Yes.
yes and it may cause damage to the transmission if filled too much.
A vehicle stalling can be just one problem associated with having too much transmission fluid in the vehicle. Excessive transmission fluid can cause the gears in the transmission to heat up and experience damage as well.
If too much transmission fluid is added, or there is something wrong with the pump
Your tranny will start to slip and damage trans. Too much fluid can cause the transmission to blow seals. Drain out the excess, immediately.
No, but too much pressure can cause gasket issues which are even worse.
Having too much fluid will cause your transmission fluid to look foamy
too much trans fluid can burn up the trans. just drain some out till it is at the correct level
Too much transmission fluid in the transmission can cause the transmission seals to leak. The transmission builds up pressure when going down the road. The added pressure can blow up they seals.
Yep. Too much fluid will cause foaming and will cause lack of lubrication. At what point this starts is anybody's guess.
Changing the transmission fluid in your LS should be performed by a qualified service technician. There is a fairly comprehensive procedure for servicing the transmission and it requires that the fluid be checked hot and cold. Too much fluid in your transmission will cause it to jerk when putting in and out of gear, the shifts will be choppy and it may even feel like its slipping, and finally there is an overflow valve that will cause the excess transmission fluid to leak out and onto the floor beneath the transmission. A qualified service technician will know how much fluid is enough and how to get it out.
It is important to keep fluids from leaking from a car. Excessive transmission fluid would be coming out of the overflow because there is too much fluid in the transmission, or because the seal has become worn.
