My question is, are brass pinch fittings on a mild steel line strong enough to finer seal and hold tight plenty for transmission line pressures? I'thou at present using a barbed hose finish attached to a standard compression fitting to better lock the safety hoses on the lines.

The history of the state of affairs. I had just cut the end of my trans libation lines near the radiator to add together a plate cooler. I used a minor line cutter, deburred the lines, flared the end slightly with a tube flaring tool and used the correct manual/power steering hose and two EFI style hose clamps, as they don't tend to cut the rubber hose similar the Hygear clamps practise.

I had issues with seepage and even had i hose come off and pump trans fluid all the way to my favorite taco stand up.

During Normal driving the 200R4 never gets higher up 160. Information technology takes it a while to warm upwardly to that also. It has a deep pan, ane plate cooler and it goes through the radiator libation get-go to help the fluid warm upwards for daily driving; and so through the plate libation and back to the transmission.

When I do repeated drag passes 3 or 4 or more, the fluid temp climbs to 220 and will go higher if I don't let it cool for half an hour. In guild to gainsay this, I am calculation a second plate cooler and am plumbing 2 ball valves just before the radiator cooler.

I open the ball valve and close the bypass valve so the fluid flows through the radiator cooler first to get some heat into the fluid for daily driving days.

I can then close that valve and open the second bypass valve, so the fluid bypasses the radiator and flows only through simply the plate coolers.

I'll follow up later and study on how effective this is on keeping my fluid temps nether command.

My pick-upwardly truck has been like this forever as well. I idea they could fasten momentarily to ninety psi or more shifting into reverse. I was told that was why it was never a good idea to use the rubber hose kits that come with most coolers on a Torqueflite. In whatsoever case a compression fitting is adequate to hold whatever pressure that might turn up in a libation line. Kevin

On the brake ;one, information technology was a quick fix until I replaced the the rusted line. I would say the brake line is probably not a practiced long term fix . information technology's ok to butt heads, just don't practice information technology with a butthead
