Change the combination power steering hose which is leaking


Is it the power steering hose or a transmission line.Honda does not usually attach power steering lines to the radiator, but the transmission cooler lines are attached to the bottom of the radiator. If it is the transmission cooler line leaking, simply replace the line from the radiator to the transmission with 1/2 inch transmission line and some new clamps.May want to do both lines while you are making the repair.

Trans fluid in radiator tray


You are leaking transmission fluid from either the fluid cooling lines that run from transmission to a separate reservoir in the radiator, or leaking from the reservoir itself. Hopefully, it's only the lines and may just need tightening to stop the leak.
There are two lines to the radiator's reservoir. One brings fluid from transmission to the reservoir, and a return line back into the transmission. Probably located on driver's side of the radiator, one will be near top of radiator, and one near the bottom. Small copper or steel lines that may also turn into rubber lines. Clean the area well with rags to locate the leak. Will probably need to have the car running to make it leak, while looking for it. You could also take a wrench and try tightening the fittings at the radiator, and tighten any rubber hose clamps that you see. If it's not the lines or hoses that are leaking, then the radiator may need to be pulled off for repairs or replacement. But 9 times out of ten, it is a leak from one of the lines.
When fixed, don't forget to check your transmission fluid level. Or keep adding till it is fixed.

1991 Chevy Lumina APV. The transmission fluid is leaking. Can this be a gasket or seal problem? Also, can it be I put too much fluid in?


Leaking transmission fluid can usually be traced to 1 or 2 problems:
  1. leaking transmission line - a line could be bent or it could be leaking around a fitting, the most common place for a transmission line to leak
  2. the gasket around the transmission pan is worn - this would cause leaking and having the filter and fluid changed should fix this problem
To answer your other question, YES it is possible to overfill the transmission fluid. Check the dipstick (with the car running) and ensure that the level stays between the recommended marks.

Transmission fluid leaking


I would determine if the leak is from a coolant line or the transmission itself.
If it is a line, replace the line.

If the transmission itself is leaking, determine if it is from the transmission fliud pan bolts area or if it is from the area between the engine and the transmission, which could be a seal at the rear end area.

Maybe, take it to a transmission shop to have it looked at.

Good luck on this repair.

Im leaking transmission fluid from what appears to


Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.

My 2003 chrysler concorde is leaking transmission fluid. what is causing that?


All depends on where it's leaking from. If it's leaking from the transmission pan, then it's going to be a bad transmission pan gasket. If it's leaking from the transmission cooler line or connections from the transmission to the radiator, replace the line or the connections or just the O-rings in the connections. If it's leaking from the transmission housing where the engine and transmission mates, then it may be the from pump or Torque Converter. The leak could be coming from the CV joint inner shaft where it connects to the transmission. Good luck and keep am eye on your transmission oil level, low transmission fluid will cause transmission failure.

Brownish fluid leaking from the small mannifold on the passenger side of the car in front of the radiator...is this transmission fluid?


Good chance it's the transmission fluid. The passenger side of the radiator is the transmission cooler side and the coolant is leaking from the transmission lines. There should be two lines, one on top which is the inlet and the bottom one which is the return line. Check to make sure there is no corrosion along the lines or that the line has not come loose at the radiator. Locate the leak and repair or replace the lines. Good luck and take care not to run low on transmission fluid, low fluid in the system will cause the transmission to burn out.
