When checking transmission fluid with engine cold dip stick shows a level above hot marking when the shown is below this problem?

There are a few possible reasons why the transmission fluid level is above the hot marking on the dipstick when the engine is cold:

* Overfilling: The transmission may have been overfilled with fluid, either by the manufacturer or by a previous owner. This can cause a number of problems, including foaming and aeration of the fluid, which can lead to transmission damage.

* Incorrect dipstick: The dipstick may not be the correct one for the transmission, or it may not be inserted correctly. This can give an inaccurate reading of the fluid level.

* Coolant leak: If the transmission cooler is leaking, coolant can mix with the transmission fluid, which can cause the fluid level to rise. This is a serious problem that can damage the transmission.

* Internal transmission leak: If there is a leak inside the transmission, such as a faulty seal or gasket, fluid can escape from the transmission and mix with the engine oil. This can also cause the fluid level to rise.

If you suspect that the transmission fluid level is above the hot marking on the dipstick, it is important to have the vehicle checked by a qualified mechanic as soon as possible.
