Spent an hour or so today trying to work a transmission line back onto the cooler. No luck... So much for "quick" connect.

Anyway after staring at the line for awhile, I noticed the flexible portion is pretty well cracked and worn. OCD kicks in, so I look for a replacement line. Turns out they aren't manufactured anymore, and its a bear of a job to disconnect the end at the transmission anyway.

So I see an opportunity to put in something better than OEM

Two ideas
1. Cut out the rubber hose, put a new one in with stainless steel high pressure hose clamps. Easy. Would it hold?

2. Replace the rubber hose with a braided SS line, threaded at each end. Use compression fittings for each end to fix to the cooler and hard line.

Has anyone done a DIY on these flexible lines and can share some tips?

 

I think robert booth was having some issues like this and actually took the lines to a local hydraulic shop and had them make some

 

I've done aftermarket coolers in Mustangs and T-birds, never did I use SS braided lines. Just high pressure rubber hose, never failed either. Transmission lines shouldn't have much pressure in them. Make sure the cooler has flares and don't over-tighten the clamps, get a decent cooler as well.
