Can I run braided hose instead of hard lines from my radiator to my trans as long as I route them away from any major heat like the headers and exhaust?

You can do that, but make 100% sure the braided lines are rated for ATF. I'm not a big fan of anything other than hard lines for any pressure application. granted, there are places you need flex, but I like to keep them as short as possible.

I use steel brake tubing just about everywhere I need to replace a line. It's seamless, and can be polished up a bit and clear coated to keep it looking nice. And it's way cheaper than braided line is.

After checking braided TEF line, which is ATF approved, I found that it isnt cheap so Summit says I can use their TEF unbraided blue hose, which is about 1/3 the cost of braided. The solid line I took off the car had short pieces of hose on each end so running hose all the way will reduce the number of clamps that were on it, which all leaked anyways.


Quick question, while the trans is out of the car can I roll it on its back to change out the pan and gasket without causing any problems or damage? It would probably sit on its back for about a day or so. By the way, the fluid was drained..


Thanks again!!

You can roll it over without a problem but you may lose some fluid from the vent tube on its top. You will also lose fluid when you pull the pan around the lowest point on pan rail. The fluid is trapped in many spaces and will find its way onto your garage floor when flipped over. Try and find a quality kit, cork gasket and a new o-ring for pickup tube if you have a T400, filter is semi floating on a 5/16" retaining bolt . Don't over-tighten pan bolts, use no sealer, flatten pan rails before re-assembly, keep all grit from blowing into trans while pan is off. I'd change the front seal and pump o-ring/gasket but that may be more than you care to jump into. The seal should be replaced as a minimum while it's out though....that's easy. Use some weatherstrip adhesive on the seal after cleaning pump body well.

Unbraided lines can be 'risky'. If a soft line takes a hit from a sharp rock, then you have high pressure oil spraying up on your hot exhaust manifolds...NOT a good combination. Hard lines are cheaper--but they are also much safer.

I'd use hardlines, they aren't that expensive either, about $80.
