Does a transmission have a breather hose?

Does a transmission have a breather hose?

Does automatic transmission have a breather? In conventional automatic transmissions, air flows into and out of the transmission housing through a vent or a breather tube during transmission operation. This requires the transmission operating fluid be changed periodically.

Why is my transmission fluid coming out my vent tube?

Overheated, aerated, or overfilled fluid levels result in fluid leaking from the dipstick tube and transmission vent. Low fluid levels result in air being drawn into the oil pump passages, contaminating the fluid with tiny air bubbles. This condition is referred to as aeration and results from low or high fluid levels.

Which is the return line on a TH350 transmission?

bottom line
On a GM Turbo 350 transmission the bottom line is the return line and the one to install a transmission cooler on. The top one is the send line.

Do all transmissions have a vent?

All transmissions have a vent to maintain equal barometric pressure inside of the transmission. If the vehicle is driven through water (as in a flood) and the water level is at or above the vent, the water will cool the unit lowering the internal temperature and water is drawn inside of the transmission.

Do transmissions have an overflow?

The other way to solve excess transmission fluid is to drain your transmission. Depending on your vehicle, you may have an overflow valve under your car that allows you to remove any excess fluid easily. Most automatic transmission vehicles do not have this, but it is available in some manual transmission vehicles.

Where does transmission fluid leak from?

The most common source of a transmission leak due to faulty installation is from the transmission pan. The pan is not mounted correctly or incorrect bolts are used to secure it. Something as simple as these bolts will make transmission fluid leak from the pan. Hopefully, the bolts just need to be tightened.

Does it matter which transmission cooler line goes where?

The top hose from the transmission cooler goes to the top pass through nipple to the transmission and the bottom hose from the transmission cooler goes to the bottom pass through nipple into the bottom of the radiator.
