I saw this at another LR forum:

Extended Drain hoses for A/C - Australian Land Rover Owners

I'd like to reroute my drain line but my transmission is still in. Wondering the best course of action, through the inside of the car or up on that narrow side of the body next to the tranny.

Thoughts?

 

You have to wonder why Land Rover didn't do that in the first place...

 

Unbolting the bottom 2 engine mount bolts and tranny mount bolts will allow you to lower the engine down by the amount of space cuttently between the bottom of the tranny and crossmember (several inches). That should give you the space you need.
