I have a '65 that was put together by apes (all thread turnbuckle and eye bolt tranny linkage for starters) I bought new pre-bent tranny cooling lines and I cannot figure out how they go. Anyone have a photo or a thousand word description?
Thanks much.

the fittings on the side of the transmission are also NOT regular inverted flair..

they are special C4 only fittings..   you can see the one on the left.. it has a jam nut with a sealing oring to lock the angle..

but inside the inverted flair.. there is usually an Oring seal..

please.. be sure to use a back up wrench when tightening or loosening the tube nuts...

a set of these will make your life easier...  HF 93137   12 bucks.

The pre-bent lines are fairly easy to route. Hopefully they came with the small u-shaped clips to keep them paired together. It cleans up the routing and prevents rubbing/vibration issues.

The lines come off the trans fittings as shown above and then wrap around the starter and tuck up along the right oil pan rail. There should be a j-shaped clip bolted to the side of the engine block to secure the lines. The lines then run under the engine mount and turn in front of the engine under the crank damper and then turn again into the bottom of the radiator.
