Transmission Lines

[GhettoRacingKid]

I got stainless steel braided AN lines. an no I do not use the factory cooler. its cleaner looking and I feel cools better

one thing with transmission fluid the original cooler was incorporated in the rad to warm up the transmission fluid and to keep it hot enough to stay within the correct operating temperature. It's good to have a secondary cooler so it doesn't run too hot but if it's too cool it can damage the transmission

Pontiacgp is right....your supposed to go from transmission to radiator than to trans cooler than back to trans..the radiator is there to warm the fluid, its important to have fluid at the correct temp...just like you would not hammer on your engine if it wasn't properly warmed up.

I didn't end up going this route, because I couldn't see spending $100 on transmission cooler lines, but you can have NAPA make hydrualic lines for you. These lines have a 4000 psi rating and they withstand heat and friction. The ends are pressed on with a 4000 lbs press

im def going braided because thats what all my lines are going to be, but thats not a bad idea.

I guess im special since mine is a drag car not so much a daily driver.

i like the braided s steel ones but the cost was 10x making my own steel hard lines. so i found the old tube bender & made new lines.cost less than $20.

I waslooking for more volume and better flow and i got it at a swap meet

Mines garage kept and it never sees temperatures under 40°. I don't hammer on the car immediately after start up and I have a digital trans temp gauge plumbed into the trans. Plenty of people do it this way and I can't say I've seen trans failure because of it. If I drove it year round, I could see issues.

If you have a drag car a cooler might not even be needed unless it is rwyb, if you are bracket racing a trans temperature gauge would help inasmuch as you can launch with the trans at a consistent temperature, a hot transmission will shift a little differently to one that is startup cold.
The same applies to engine temp - oil and coolant.
BTW all the trans coolers I have fitted have been recommended to run through the cooler first, then through the radiator.
