Transmission line is leaking

Anyone replace their own transmissions lines on a 2006 TRD4x4? What does it cost and how hard is it ? Thanks

 

Check the fittings first. More than likely you just have one that needs tightened.

Fittings are always the weakest link.

 

The fitting looks very rusty and it looks like it could break. The lines are original with 140k with Pa road salt winters.

 

Had this happen on my Corolla. I replaced them with some of that 'bend your own' brake line from Autozone.

 

Are these the fittings on the passenger side of transmission. Any pics

 

No pictures, its on my Preacher's truck, he was going to attempt to fix himself. Last night he called to tell me he was having it towed to dealer this morning. Thanks for your input.
