Quick Answer: What happens if transmission lines are backwards?

If you had it reversed, the pump would be trying topush fluid through the bottom of the cooler, up through the cooler, out the top into the bottom of the rad, and up through the rad to the top. More weight to push.

Does it matter which transmission line goes where?

Generally the higher line on the radiator has fluid going INTO the transmission and the lower one goes back to the transmission, so the higher line has fluid coming out of it and the lower line sucks it back into the transmission.

Are transmission cooler lines directional?

Can Transmission Fluid Flow Through Either Direction on a Transmission Cooler. Helpful Expert Reply: … The cooler can have fluid flow in either direction through it.

How do you find the return line on a transmission?

The surest way to find the return line in a transmission cooler system is simply to run the cold engine for about 15-seconds while it is in gear. Then immediately feel the two transmission lines.

How do transmission cooler lines connect to radiator?

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.

Can I use rubber hose for transmission cooling lines?

You can use rubber hose, but make sure it’s transmission cooler line rated. The pressure is quite low (12-15 psi). Double clamp it or use FI type clamps instead of the worm-drive style.

Why do transmission lines go to radiator?

Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. … Your car’s transmission lines are essential to preventing the transmission from overheating by carrying hot fluid away from the transmission until it is cooled and subsequently pumped back into the transmission.

Does it matter which way you mount a transmission cooler?

More often than not, transmission cooler orientation does not make much of a difference. While some may argue that you need to install a certain type of cooler inverted to prevent air bubbles, the transmission line pressure it strong enough to push fluid through the entire cooler to prevent this.

Which way does transmission fluid flow radiator?

According to the FSM, the tranny fluid flows out of the front port on the tranny, goes to the passenger side of the cooler in the radiator, exits the driver side of the cooler, and goes to the rear port on the tranny. In mine, something appears to be backwards.

Can you bypass transmission cooler?

When the transmission is cold, the thermal bypass will “bypass” the cooler so it can bring the transmission up to operating temperature more quickly. … The bypass works very well with other coolers, such as the Tru Cool™ 49211 cooler. So if you already have a cooler you like, adding the bypass on is definitely okay.

What runs through transmission cooler lines?

Transmission Cooler Line System

The transmission cooling line system is vital to any automatic transmission. It circulates the hot fluid away to the radiator via cooler lines and returns the cooled fluid back to the transmission.

What causes transmission cooler lines leak?

The most common transmission cooler failures are due to either a leak in the body of the cooler itself, or a clogged line caused by something flowing through the system. This most likely is from the transmission itself.

Does transmission fluid run through the radiator?

All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.
