Transmission lines leaking

[ascamaro]

On my 2003 Montana with 92,000 miles, the top transmission line that goes into the radiator has recently started leaking. What is the best way to fix it?

Thanks

Older lines use a flared fitting held into the radiator with a line nut. Sometimes, tightening up the fitting will fix the leak.
Other fittings use an O-ring. These fittings can be disassembled ad the O-ring replaced.

I have the o-ring style. I took the plastic sleeve off and popped the clip out. Then pulled the trans line out and there was no o-ring on the line or in the fitting to the radiator. So i cleaned the fitting out checked and rechecked for any sign of old o-ring and nothing. So i put a new o-ring on the line and it still leaks. Is there special kind of o-ring that goes on the line?

Thanks

You can get just the fitting at the dealer and there is a special release tool to remove the lines which is much easier

Are you saying i need a new fitting? The line was easy to get out and didnt require a tool.

There is a special realese tool and I have the complete set,with the 3/8",1/2" and two 5/8" release tools which I bought from the Cornwell dealer that used come around in my area.Most parts stores will sell this special release tool for these Jiffy tite fittings as a set including any Mac,Matco,Cornwell and Snap On tool dealer.All you do is slide the plastic cap back and install this the special release tool (3/8 release tool) making sure it is seated in all the way and give the tool a twist (60 degrees) removing the line.This is the better and faster way than picking the clip out.The other option is to buy a new fitting from the dealer
