Why we don't use hose clamps for transmission lines.

Cruising back from tristate Saturday night with one of the lousiville guy. He starts flagging me down to pull over. I get out. He says the trans is slipping, and something isn't right. On a fresh 4L80E install we're highly doubtfull that it's slipping, but know that it now goes nowhere in drive :(......upon further inspection we found that one of the lines going to the tranny cooler mounted under the bed has come loose, and blown ~7qrts of trans fluid all over the bottom of the truck.

Here's what it looked like after we got back with a case of trans fluid, some tools, and some parts to repair it on the side of the road.



And of course the owners response to me taking pictures of the misfortune with my phone :D




The moral of the story?....Don't use hose clamps on your transmission lines kids. Way to valuable of fluid to chance it with some clamps. Spend the extra cash on the AN lines. I know one owner thats switching already!!

Re: Why we don't use hose clamps for transmission lines.

This is exactly why I made hydraulic hoses for my tranny. -6 (3/8" ID) feed and return lines to the rear mounted cooler. Considering the hose is rated for 13,000 continuous psi, they should outlast the truck. Added 2 qts to the total system as well (from 13 to 15).

Only difference on mine was the line blew off, landed on the DP, and a 4' flame shot out the p-side wheel well. Looked like Gwen Stefani concert there was so much pyro action.

Fixed the link issue.....sorry about that, I was being copy/paste lazy this morning.

Yea it was a "fun" time. I'll let nesbeth tell about the two drunk guys in the GTP that showed up and tried to "help". One was telling us it should only take a quart or two of fluid. The other was argueing if it was AWD or not. Kinda humorous actually, even moreso considering they did a "flyby" a few minutes before with their middle finger hanging out the window....I tell you, these Ohio folks are screwed up :D

I used all compression fittings and aluminum hardline on mine... first time we started it I'd forgotten to tighten the return line on my B&M cooler behind the grill ... Pretty good volume coming out of those trannys :lol:

Owwwwww! Your beating on my baby! As soon as it's practical, go somewhere and have all the old fluid flushed out of it and replaced with new DexronIII. That way you get all the stuff out of the converter and the drums as well. You should be fine if you get all the burnt stuff out. What will happen is it will cook the fluid in the pump and the converter when you run it till you just coast off to the side of the road. You gotta get all of that crap out of there.

I did the same on my cooler. Aeroquip makes some ends that have the factory inverted flare, that crimped on to 1/4 hydraulic hose. Could probably get them crimped onto braided, too, haven't tried.

Re: Why we don't use hose clamps for transmission lines.

You can run type F or Dexron III, preferably a name brand. No gas station or chain store brands. This is so you get more consistency from quart to quart. Best type F is Ford, Penzoil, or Valvoline.

Dexron III is GM, Penzoil or Valvoline.
What is the difference?
Type F has a lower viscosity index rating.
Basically it's thinner. It even flashes at a lower temp. There are time when a quart of type F has been installed in a DexIII trans to eliminate shudder.
Now, because type F is thinner, it also means it doesn't hold up to higher temps as well as DexIII. The idea is it should not be hotter because it is made for very little slip. Whereas DexIII is made to actually allow a little slip. Watch your temps and type F is fine. In a 4L80e it less of an issue because your just not taxing that trans like you are a 700. For example, a 700 is constantly applying a 2-4 band. This really heats up the reverse input drum.
The is NO band apply on a 4L80e unless you manually pull it into 2nd gear. So that heat generator isn't present.
Hope that helps you decide which to run. Basically F is fine, use a name brand, and do not under and circumstances put any synthetic in it.

COOL, I have run Ford Type F from day 1. Thats what I put back in it the other day. I will get it flushed like you said and fill it back up with the same.

Thanks again
