Where are automatic transmission cooling lines located?
There are two types of transmission coolers, the type found inside the radiator or the kind that is external to the radiator that usually sits in front of the AC condenser. The oil cooler hoses are made of both rubber and metal.
Are transmission cooler lines under pressure?
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.
What happens if you put transmission lines on backwards?
You may want to flush the lines and or cooler- if the lines are backward you could have dislodged some debris and it is working like a check valve.
What causes low line pressure in a transmission?
Line pressure is normally effected by throttle position and the gear range. Pressure that are lower than specifications are usually caused by leaking seals or a worn oil pump. Higher than normal pressures are usually caused by a faulty pressure regulator.
What’s the best way to install a transmission cooler?
A can of cooler flush, which most shops have, followed by being blown out with air is the correct way to do it. When installing rubber cooler lines to metal lines always put a small flair at the end of the metal line Not too big because you will tear the line on the inside during install. Then place a clamp just ahead of the flair.
What are the lines on a transmission cooler?
Barb to Barb – Used to connect two rubber lines together. These fittings are common for when you install a transmission cooler and keep the existing rubber lines on the vehicle. This type of fitting is found on both the transmission and radiator where there is a pre bent transmission line.
How are cooler lines run in a hot rod?
A stopped up or severely restricted cooler or cooler lines can do the same. When installing more than one cooler, its advised to put them in parallel with each other, This means one line from the transmission is split with a Y and one line run to each cooler then out of each and into a Y back to a single line running to the transmission.
Can a transmission cooler be in contact with the exhaust?
If the cooler lines were in contact with the headers, it would super heat the fluid when the headers get hot. Make sure there is no contact so you won’t have a problem. Always keep transmission cooler lines factory or otherwise as far away from the exhaust as possible.
