Tranny lines - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I need two tranny lines. The ones that run from tranny up to the front. Where can I find these at. Was hoeing to find them already bent, so I dont have to make my own. Who sells them?

Not sure where you would find pre-bent lines, besides the junkyard. With the correct equipment (tubing cutter, bender, and flare) you can easily fab your own. How much $$$ do you have? I’m a huge fan of steal-braided line (and believe it’s worth the money).

sam's 72 · 04-03-2004, 12:11 AM

I thought about braided lines. Might go that direction.

cdowns · 04-03-2004, 12:23 AM

most vendors carry or can set you up with the prebent likes either in regular or stainless
LMC BROTHERS INLINE TUBE ETC

prebent lines are pretty much impossable to install on an assembled truck. It is money waisted IMO onless you have a bare frame to hook them to.
I'm running rubber lines from Parker. Jiffy hose I think they call it. Push on type fittings, holds up to 300 PSI before it pops off the fittings...no clamps required.
Kinda expensive I hear...but mine was free.

bouncytruck · 04-03-2004, 02:16 PM

If you run rubber, make sure they are make for transmission fluid.

Longhorn Man · 04-03-2004, 11:59 PM

I agree, fuel line will get you home, and may last a couple months or longer, but you will end up making a huge mess one day...mine went on the 2nd day at a new job, the boss wasn't too happy when i left a trail going clear across the parking lot, which was just paved months before.
The set up I am using is specificly for trannys and other hyd aplications, often used in comercial aplications for tranny lines.

Stepsides 4Ever · 04-04-2004, 02:45 AM

You didn't say for what tranny...don't overlook the set that Bowtie Overdrives makes for the 700R4...

Longhorn Man · 04-04-2004, 12:09 PM

Trany lines are pretty mucht eh same from one tranny to the next, if bow tie OD charges an arma nd a let for there lines, like they do for almost everything else, then shop elsewhere. (Not implying there stuff isn't worth a lot of cash...)

I got some if you'd like em. I'm in Garland Texas. $20? they're good

Low69CST · 04-04-2004, 07:14 PM

I'm puttin braided lines on my truck. It's expensive as heck. One reason I aint had my truck on the road yet. You can get adapters to take the radiator fitting to AN line. Also, i was told the fittings in the transmission unscrew to a NPT. I haven't tried taking mine out yet. As soon as I get my brakes done, i'm setting in on this.

Jemost 72 · 04-05-2004, 03:02 AM

Chevyguy, put me in line for those lines if Sam passes on 'em....

sam's 72 · 04-05-2004, 06:36 AM

Jemost I sent him a PM. I want the lines

Dean · 04-05-2004, 08:33 AM

I put a transmission cooler on my latest K20 and made hoses from Aeroquip. They were expansive but pretty impressive so far.

**COBALT** · 04-05-2004, 05:01 PM

I'll have to disagree with Longhorn Man on this one. I got my TH400 cooling lines from Inline Tube and they fit just fine - on an assembled truck.

They have a set of lines that run from the transmission case to the stock 4 core radiator. I don't know if they have ones for a transmission cooler. I had mine installed in about an hour after making sure they were running past the engine correctly.

Longhorn Man · 04-05-2004, 05:32 PM

Hmmm, I wonder what the (*&$%^& I'm doing wrong then.

**COBALT** · 04-06-2004, 01:13 PM

You have a set you're trying to fit?

Don't bother hooking them to the hooks on the oil pan if you have those. Run them above the cross member, and connect them to the transmission FIRST. Then run them to the radiator since that end gives you the most flexibility.

Either that or they gave you the wrong ones....

I have a SBC by the way. It probably depends on what engine you have. Are you trying to fit them around that caddie engine? Maybe that's the problem.

Longhorn Man · 04-06-2004, 04:58 PM

No, I don't have any right now, I have tried in the past, and then I have tried at work on the P-30's...never had any luck.
oh well, no big deal, like i said, i don't use hard lines anymore.
