Where are transmission cooler lines?
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.
What are trans 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 happens if transmission cooler 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.

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.
Can you make your own transmission cooler lines?
You can make your own steel lines from scratch, your local parts stores should have the correct fittings. Bending steel lines is hard to do especially if you want to keep it looking nice.
How much pressure should be on a transmission cooler line?
there is at idle between 20-50 psi but during use pressures in transmission lines can reach 100 psi or more. if you are going to use rubber lines be sure to use barbed fittings so the hose does not blow off. Cooler and lube pressure are about the same at 5-30 psi.
Can you use copper tubing for transmission cooling lines?
A GM service manual I have states “when replacing transmission cooling lines,use only double wrapped steel lines meeteing OEM specs,NEVER use aluminum or copper lines,as these materials lack sufficent strength to handle the vibrations encountered in normal driving conditions and may (MAY!)
Can you use compression fittings for transmission lines?
They can be used for brake lines too…which is high pressure. They can be a pain to do right..but they work. I have used them on transmission lines , gas lines and also brake lines with no problem.
Can I bypass the radiator transmission cooler?
Expert Reply: I verified with my contact at Derale that the Derale Hyper-Cool Transmission Cooler, # D15960, will work to bypass your radiator and cool your transmission fluid. If you choose to mount the cooler further away from the radiator, then you will likely need an additional length of hose.
