What trans. lines are people using. Going to the stock radiator.
Aftermarket or modiflied stock lines.

I used rubber line that had to be heated up and pushed into Barbed AN fittings. Next Time I'm out in the garage I'll see if there is a name on them. They were recommended to me over the steel braided lines. Been on there for 2yrs not and not even a drop of fluid from the connectors


Edit....just noticed you were going to the stock radiator, why not an aftermarket cooler?

I have a cooler, but that's on the low pressure return line, which I can fit it to the trans with a rubber hose. I'm more concern about the high pressure line going to the radiator.
I didn't want to really use a rubber hose on that line.
Did you just cut the stock lines at the trans and adapt to the rubber hose or just ran rubber hose all the way.
I was also wondering if the stock lines were big enought for cooling the TH-400.
I don't know if the 4L60E lines are the same diamater as the TH-400.

I went from a m6, so mine are all aftermarket. I didn't use regular lines, they are some high pressure hydraulic lines I believe. I can't check till I get home though.

I used the basic -6 steel braid since the 80's.
Never an issue, easy on & off.
Not sure what fitting is on a stock radiator, but I'm sure they make one or you can piece 2 together to fit a -6??

Yeah, I like the bigger size -6an.

Did you get a chance to look at your old 8" converters?

Thank you Sir.
I'll do some research.

Guys there's some advice here I feel that I must disagree with. And that is the use of push lock style transmission hoses. It's a safety thing. Period.

The transmission lines really do need to be securely fastened to the fittings with a clamp or a/n type fitting. I have personally witnessed 3 cars lose their lines. One was a turbo car at a high dollar out of state street race, the other two were at the track. Do yourself a favor and do not use push lock style hoses and fittings. It will bite you in the *** when you least expect it. If it hasn't yet, it is only a matter of time. Seriously, not calling anyone out, but it is a risk I would not take.

What are those lines & fittings rated at??
I've seen several guys use them on their dry sump and other systems.
I have never tried them, I'm an old & faithful steelbraid guy!!

+1 This is truth!

I have a more basic question. What type of fittings are required to connect to the stock TH400 Cooler fittings on the tranny? Secondly, how do you route the lines to the cooler that is mounted in front of the A/C Condenser?

Thanks,

Joe

I personally don't like pushlok hoses.... But "line pressure" on a TH 400 is not the pressures in the coolant lines. To get line pressure you have to use the case pressure port not the cooler lines. I've been told the cooler lines are 10-20psi

Gilbert@Ace Racing

Cooler line pressure is dictated by converter charge pressure, which is dictated by the builder. Typically it is in the 40 - 70 psi range, but I have seen it as high as 90 psi over the years in different builds. You really should not put information out there if you do not have first hand knowledge. Seriously, there is too much misinformation about transmissions out there as it is buddy.

What are you talking about regarding line pressure at the diagnostic pressure port?
