Replacing leaking transmission cooler lines under front bumper

Could be the transmission cooler lines. Check for cracked hoses or loose hose clamps.

transmission --lines leaking,damaged cracked===leaking cooler ==pan gasket==seals- look under vehicle as to ares of leak if up front by engine possible lines/cooler by trans lines/gasket/seals/trans case damaged

most likely it is leaking where it connect to the Trans cooler behind the front grill. If the trans lines use clamps you will most likely just need to tighten them up. If it uses quick disconnect fittings you will need to buy a set of quick disconnect tools about 10$ at auto parts store pull the leaking line off and replace the seal inside the line. Good Luck I hope that helps.

This is an interesting one. Where is the transmission fluid leaking from? If it is coming out of the transmission where it meets the engine, then you are looking at replacing the front transmission seal, and to do this you will need to pull the transmission. If it is not leaking at this spot, then you are looking at a line leak, and will need to replace the bad line. There are going to be two lines for the transmission, make sure that yoyu inspect each one of them thoroughly/ They are the usual culprit when a transmission starts to leak.

CHECK UNDER VECHICLE IF TRANSMISSION FLUID UNDER TRANSMISSION MORE LIKELY PAN GASKET LEAKING FLUID.IF FLUID HAS NOT BEEN CHANGED THE PAN GASKET GET HARD LEAKS FLUID.THATS IF YOU HAVE SLOW LEAK.IF YOU LOSING LOTS OF TRANSMISSION FLUID ITS .LEAKING AT TORQUE CONVERTER SHAFT SEAL.LEAKING AT COOLER LINES.CHECK COOLER LINES FROM RADIATOR TO UNDER CAR WHERE COOLER LINES GOES TO TRANSMISSION. AND CHECK LEAKS AT FRONT DRIVE SHAFT AXLES SEALS

Hi!!
First you got to pinpoint where the leak is coming from. Place a couple of sheets of newspaper under vehicle, wait 30 min. to an hour and look under the vehicle at the newspaper sheets, where you see transmission fluid, look up, that's where the leak is.
The most common places where the transmission leaks are:

• Transmission fluid pan,
• transmission cooling lines (there are 2 steel lines that carry fluid to a cooler coil in front of the radiator and back.) due to the location, going over a bump or a rock may kink, bend or puncture one of the lines.
• Transmission front or rear seals.

You are talking about a tube, I assume you are referring to one of the cooling lines. If it is leaking at one of the terminals, usually at the transmission fluid cooler in front of the radiator, some times just tightening a little will take care of the problem. If the line is punctured, remove the line and take it to a hardware store like ACE Hardware or similar to have them install a pressure fitting. If you are to DIY, no need to remove the line. It can be done from under the vehicle. Either way, the cost of the repair will be about $10. If you take it to a Shop, God knows how much it'll be!!

Good Evening. Unfortuantely there is no easy path to a right answer here without removing the skid plate. In front of the engine are transmission cooler lines and other miscellania. The best advice i could give you is take down the skid plate and have a can of brake cleaner handy to clean everything off while you have it turned off then have someone turn it on for you so you can visually see where it is coming from. Hope this helps and if you have any more questions feel free to ask.

TRANSMISSION LEAKS COME FROM TRANSMISSION OIL PAN GASKET LEAKING.OIL COOLERS LINES LEAKING.LEAKING AT TORQUE CONVERTER FRONT SEAL.TRANSMISSION SPEED SENSOR SEAL LEAKING.FRONT AXLE SEALS LEAKING AND LEAKING AT TRANSMISSION COOLING LINES TO RADIATOR.CHECK ALL YOU WILL FIND LEAK.IF YOU HAVE FAST LEAK OR PRESSURE LEAK.WITH CAR RUNNING IN PARK EMERGENCY BRAKE APPLIED LOOK UNDER CAR IF YOU SEE FLUID LEAKING OUT IN LARGE QUANITIES.COOLER LINES LEAKING OR TORQUE CONVERTER FRONT SEAL LEAKING.IF YOU HAVE SLOW LEAK THE LEAKS HAS TO BE AXLES SEALS OR PAN GASKET LEAKING OR VSS SENSOR SEAL LEAKING.

cheapest and easiest is to cut it at the leake and rejoind with a compression union. How is the line damage? bent, kink, chafe hole?

2 fixes here, either replace the lines, or find the one or both that are leaking and cut them and connect them back together with gas line hose the same diameter as line with hose clamps. Cheap fix and it works.
