If you re-post your question using Make Model Year of the Car I can be more exact
For most Automatic Transmission Lines in a car there are two cooler lines that can leak.
Some have more
Some very rare ones have none.
Transmission fluid can leak from many places. It could leak from the actual transmission itself, or any of the tubing that goes from the transmission to other parts of the car.
Numerous places, If your not counting lines then rear seal, front seal, pan gasket and I can go on...!
AC transmission lines are 3-phase, DC transmission lines don't have phases. It doesn't matter where they are from.
It could be transmission fluid. Many transmissions are cooled by running a line through the radiator. Check for small tubes going into the radiator, if you only have the two large engine coolant lines, you don't have a transmission cooling line in the radiator.
Answer youtubeAnswerThere are two categories of 'power lines': 'transmission lines' and 'distribution lines'. Transmission lines comprise lines supported by transmission towers ('pylons') and distribution lines comprise lines supported by poles. In both cases, their function is to transport electrical energy from the generating stations to the consumer. Transmission lines are normally part of the grid system, a network which links many generating stations and load centres (usually located near large towns, for example); distribution lines link these load centres to consumers -factories, commercial buildings, residences.
It depends on which distributor and transmission you have. The stock distributor has one vacuum line going to it. An autostick transmission has one line. If you have a manual transmission and a Bosch 009 distributor like most people do, you have no vacuum lines.
A 4.0 ford ranger will hold 10 quarts of transmission oil. This is if the if the transmission is totally dry including the lines and the transfer case.
Engine coolant can enter an automatic transmission if your automobile has an integrated radiator and transmission fluid cooler, and a leak occurs in same. Many automobiles have integrated radiators / transmission coolers. Another less likely scenario is that the vehicle was recently flooded or parked in flood waters.
Well there are many possibilities... Perhaps the transmission seals have become worn, and caused fluid to leak out; resulting in transmission failure. There are really so many possibilities, you're best advised to get the assistance of a professional transmission repair expert for an accurate diagnostic evaluation. But be careful...They can be "Shifty!"
Many of them have their own emergency generators, ready to take over if the commercial power fails.
According to the 1997 Mercury Mountaineer owners manual : Your 4R70W automatic transmission capacity is ( 13.9 quarts ) * that of couse would be for the transmission , torque converter , lines , transmission cooler , etcetera *
about 4 in the trans, about 5 in the lines.
