Which way should I run my trans lines??

[onefastjackass]

Ok I have an 87GN with the 2004r and don't ike the way my trans lines are running.It looks like someone put different lines in it and they are touching the exhaust tube were it comes down from the turbo.It is running between the block and that pipe.What is the best way to run the trans lines to keep them away from heat.Also should I worry about how long the trans lines are so that I don't have pressure drop or not??

Thanks Kevin

To the frame or body?

I ran mine off to the side and attached them under the body with insulated clips. Took some time but now when I pull my motor and trannie it makes life much easier, I seem to change motors more often than engine oil. Now I do not have to fool with a set of trannie lines intertwined with the engine and trannie.

You just need a double-flaring tool--$25 on eBay--to make up the ends. Same tool can be used on brake lines, custom fuel lines, etc. and steel lines are safer and cheaper than any "soft" alternative.

Having the lines a little longer is not a problem, just do not kink any bend. Use coat hangers to model bends.

Did you use any flex line between to trans and frame or just use the hard line??

Hard line

But I ran mine so that there was over a foot of line and the first 45 degree bend before the first clamp and the clamps have thick neoprene rubber liners--came from car show vendor. This permits some flex along enough steel pipe to reduce the possiblility of stress breaking the line over time. I also use polyurethane motor mounts which act as engine movement limiting devices. If you run soft line either you have to buy hi-dollar AN fittings/adapters and pipe or use hose SPECIFICALLY (very important) designed for use with transmission connections.

I just prefer hard line--looks cleaner, cheaper and reliable. Mine are one-piece lines from the trannie to the radiator cooler. Take your time with the bends--do it once, do it right. If you've got money to burn use the AN fittings and lines, they are also excellent and many folks like the "look".
