Question about 1993 Chevrolet Lumina APV
I have a 1992 chevy lumina apv that is leaking transmission fluid from what appears to be a transmission line but the fluid is so coarse I cannot tell which line its coming from. Its leaking from one of the lines under the radiator. It only leaks when I start the car up and its at idle, when I shut it off it stops, any suggestions?
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.

This is transmission fluid tht is leaking for sure.
You will have to check it out if its the pipe (rubber) tht is fractured or the pipe at the radiator itself where the flexible pipe (metal) fits.
Basically the transmission fluid runs thro the radiator once the engine is running for cooling purpose, one of the pipes is inlet and the other one is the outlet.
A quick cleaning of the lines with degreaser might be of good help to locate the leak.
Hope this helps!
