My TH400 cooler lines are in rough shape. They have been repaired (brazed or soldered, whatever the term is) and have been sleeved in a few places. They've leaked at different places and it's time I replaced them.
Does anyone have any experience with Classic Tube's products? Found them for sale through Summit.
I'm using my phone to post and unfortunately cannot post a link. Thanks for any suggestions.
No experience with those, but when I did a 401/th400 swap on my 79' CJ7 I just got a pair of four foot long steel lines from the local parts store and used a hand held tubing bender to route them how I wanted. Saved a bunch of money. They had the proper fittings for the transmission. On the other end I just cut, flared and finished off with a short piece of rubber transmission cooler line to the trans cooler fittings.
I think the reason he used rubber hose is he is running an auxilary tranny cooler.
I bend my own for most stuff for a lot of reasons. Try Harbour Freight for the tools.
I haven't used Classic but I have used Fine Lines in fact looking at a complete set for my son's Camaro right now (the wife loves car parts in the living room). Most of those companies are the same and make quality stuff, the fit is usually good but may require minor tweaking. If you buy OE they will oxidize quickly, if you buy stainless they are hard to get to seal at times. This is especially touchy on tranny lines, you have to crank them down hard and if you aren't careful you can over tighten the fitting into the trannny.

I went to Advance this morning and between my daughter being a terror and a useless employee, I made it nowhere.
They sell a flaring kit for $35, looks kind of chincy. They also have a tube bender for $15, looks ok.
I asked if they sell steel brake line and he said "for what vehicle"?. I explained that I need an 8 ft. piece (to cut in half) so I can make my own lines. He looked at me like I had three heads.
I'm gonna run to Harbor Freight this evening and also stop at another parts store where I usually have better luck.
I have no experience with this. How does the flared line seal inside the fitting? Should I be left with one simple fitting on each end that spins around the line to allow it to draw into the tranny or radiator and create the seal? I need a moron diagram. The lines I have now have about three fittings in a row at each end and it just seems more complex than it needs to be.
The lines I used are 3/8 O.D. and the fittings take a 5/8 wrench if that helps when looking for the lines at the store. I have a cheap little hand tubing bender that I used to bend and route them away from the trans, above the exhaust and to the right frame rail. When cutting the line in half make sure you have a fitting on each end and use a tubing cutter. I'm not sure what the fitting on the radiator end looks like because I never had them but the trans end will draw in and seal itself up. On the other end, I just flared it so it wouldn't pull out of the rubber line past the hose clamp. I rented the flare tool for autozone. The fittings on my radiator and trans cooler only take the rubber line so I had to use it. Here's a few pictures. I guess I need to fix my leaking vavle cover now that I looked at them.
Not sure I ever seen an 8 foot hard line? As mentioned make sure you have your fitting on BEFORE you flare the line.
There are usually brass fitting that go into the tranny and the radiator that the lines screw into. It is designed this way so that if you cross thread something you haven't screw up a component just a brass fitting. Typically your put the fitting in first and tighten it and then thread your line in and tighten it hold the fitting with another wrench.
I typically don't like tieing the line to the frame without a rubber hose to absorb the flex and vibration, under certain circumstance it could cause an issue. If you choice to do it use a soft bracket as modiv8ya did to absorb some of it.
I have several style benders and I prefer my spool type when dealing with smaller lines (3/8 and down). It is compact and fits into places that other benders wont.

The 8' ft piece was just a thought. Sorta like buying a 12' 2x for two 6' pieces, Haha. Had no clue what lengths they came in.
I am not going to attach mine to the frame at all. I plan to pull off the original lines and use them as a template for bending the new ones.
My setup now has three fittings going into the trans. The one that came on the line, going into another then another that goes into the transmission. Seems redundant. Can't I just thread the fitting that came on the line right into the transmission? Or should I have atleast one fitting in between in case I over tighten and damage the threads in the transmission housing.
Thanks for all the input guys. Just don't want to "rig" it and do as solid a job as possible.
