Close Call!

So I got my gears in and about 500 miles on them. I decided to take it on the freeway yesterday and see what it has off the line now. Everything was going good since I the traction light kept flashing.... I get up to about 80 when I let out of it and start dropping back to cruising speed. I check my mirror and smoke starts pouring out from under truck like there is a leaf fire. I get the brakes hard and pull to the berm and hop out. Trans fluid is pouring out by the bell housing. At this point I am pretty concerned and called AAA to get the truck home. I get under the truck and started to look for a hole in the case even though I didnt hear any sounds when it happened. I found the Pressure line for the cooler came out from the transmission and was the source of the leak. Now I am going to convert everything over to -AN braided line and hoping since I was on decel and stopped within 20 seconds of seeing smoke I didn't wipe out 3-4... Truck has about 30k on it so I will use this time to pull the pan and change the fluid.

Damn. Lucky it didn't burst into flames. Hot tranny fluid is like gas on a fire!

When I had to call my wife and told her I though I just blew the transmission in my truck I was actually hoping it would catch fire. LOL.... I would of started over with a 6.2

believe it or not i know the feeling you went through, it happened to me on the same 4l60e im running today, was on I10 heading home from baytown when the transcooler line blew off when i hit the gas peddle, best damn smoke show i ever been to lmao!!, had a few miles to go before the first store :( made it in and they didnt have enough fluid ( damn ) it was barely showing on the stick, didnt have a choice limped it another mile or so to another store, bought all there fluild ( 14 quarts total ) cheap chit at that, ran it for a month drained it and added some advance special ;) shes still running today behind my 408 :)


best of luck hope nothing inside went wrong !

My truck when up in flames one day when some tranny fluid shot out the dipstick tube and hit the turbo manifold . I got it put out before it done to much damage. Talk about a panic attack!

I got all the lines except one made up since I was short one fitting. I pulled the pan last night and the fluid was just above the top of the filter. It pumped out enough that I didn't get the usual shower. I drained it into new foil roasting pans so I could look for carnage but couldn't feel any grit and the color was still bright red.

I did notice there were a few bolts that hold the valve body in had some very small amounts of metal magnetized to them. Not sure if this was from standard wear or if i should be worried.

Here are a few pics of the of the Braided setup. BTW anyone looking to do this NNBS uses -6 straight cut O ring into the transmission and coolers. Don't convert the radiator cooler fittings since they have a large washer that seals the trans cooler to the radiator end tank and holds in the fluid.... Don't ask how I figured this out..

Bracket and isolator clamps I put in to hold the lines still by the bellhousing

Very nice. I was behind TvsQuez one time in Cali near Bakersfield and his cooler line popped off and did the same thing. I was behind him and got tranny fluid ALL over my truck :rofl:

Love the lines, I have been wanting to do something very similar with mine. Should be alot stronger, IMO.

Looks good, make sure you get that line off that headers though lol

That pic is very deceiving. They are actually closer to the bell housing than factory lines. My head was under frame rail / header when I took that one.
