Lisle Jiffy-Tite 22930.  

Um, I don't think that tool helps at all with the transmission line connectors.  That tool is for fuel lines (if it's the right size) or perhaps A/C lines.

 

The Transmission and oil cooler lines are push in, then there is a separate clip that goes the side of the connector to hold the line in the connector, then a plastic cover goes over the connector that prevents the clip from coming out.

 

Note, this is w.r.t. the 4l80e.  Perhaps the 4l60e uses different connectors...

Buy a few extra of those little clips because sometimes they go flying.

perhaps indicate what specific vehicle you have, including engine, transmission, and if it's 4wd

Must have changed from the GMT800s then.

I used them today on mine, worked perfect!  The 22930 for the transmission lines and the the 22940 for the engine oil cooler lines.  These are for the lines that go into the radiator.  They do indeed make other sizes for the fuel and AC lines, haven't bought them yet.  Oh, and even for the heater core lines too.

Could you post a pick of your fittings?  I just double checked in the full-service manual for '04, and it shows the same fittings for the 4l60e as for the 4l80e, where you should remove and replace the clip that holds the line in, not just spread it with that tool...

You know Dave, I just realized that we're dealing with an 800 and I have a 900.  Are they different?  If so, my apologies!

Maybe, I don't know what kind of connectors GMT900's use.

Well, they look exactly as you describe them.

If it's the same fitting, then I don't see the point of your special tool, as it's easy enough to remove the clip and then the line can just be pulled out.  And the clips supposed to be replaced anyway...

Because they don't fly away when using a pick to remove them.  And it makes sense that they would want them replaced after using that method to remove them.

 

Look, these are similar to GM specific J-tools for removing the lines, not something conjured up in our minds.  Works fast too once one becomes familiar with their operation.

Well, you are free to do whatever you want, but for me, I'd rather follow GM's guidance on replacing the clips vs saving the few bucks and reusing them and taking on the added risk of them failing from being stretched out and the line popping out, at that becomes a much more expensive repair.

Well, that's the thing Dave, I am following the shop manual.  I just reviewed one of my copies (AllDataDIY) and it says nothing about replacing the clips and shows the use of the tools I showed you.  That's why I bought them.  Same procedure for all of the transmissions used on the GMT900s.

I know this thread is a little older but looking at replacing the lines on my 2001 Silverado 1500 Z71 and was looking to purchase the Lisle 22930 tool.  I thought that tool would work on all the connections for the transmission, radiator and cooler.  If this is wrong please let me know so I can purchase the 22940 as well.

If your fitting is the same, you don't need a tool. Just remove the clip, CAREFULLY, the pipe can be removed. Then put everything back together. You can re-install clip and then push the pipe in or install afterwards. The clips can be purchased at parts stores if you lose one

I know the tool is not needed but seems like it would be easier to use the tool in the hard to reach places rather than trying to pick off the clips.

Think the point is it is personal preference.  Can be done either way.  Pick your poison.

      What I think you're saying is there is supply here at home, and in Venezuela, and we could ease pricing if only it were favorable to do so.   Well, yes?   But that's not the current market. Supply isn't what could someday exist, if only, it's what producers are willing to produce and sell at a certain price point.   The national price of single family homes would come way down if we'd just slap together a few million homes this summer.   RAM and GPUs would get a lot cheaper if we just set up some factories to produce a bunch more and stopped using it to build out AI data centers.

      The turn signal/multifunction switch is faulty.  I've seen a few of these go bad at work.

      If we actually used any significant amount of that source in the USA then I'd agree but we don't. We've had that discussion before. We drill and pump more than we use. Thing is, we sell. We export. Gas and Crude. It's more profitable so any shortage here is self inflicted and LEGAL.    I worked a gas plant that has multiple fuel sources available and I worked in the furnace and boiler plant in that facility. I'd had days we swapped fuel types four times in a twelve hour shift which isn't done on supply but on margin. Two of the fuel sources are internally generated. Tail gas and DAK, both of which are sold as well a consumed. We always had more than we needed to run the process but we chose the fuel that produced the best margin not bought at the cheapest price always. A good bit of math to that and back in the time that was done on a slide rule.     I worked the Shale Oil Semiworks of Chevron Research and CONOCO Research in Salt Lake City. That process never went into production although it was very successful. Why? Did we lack oil bearing shale? Nope. Price of crude never made the margins work. That was in the late 70's early 80's. Remember history? What was happening then was a reaction to that situation. It didn't drive it. If so then it's easy. This isn't a supply and demand thing. This is a profit and margin thing and AI rules that now.    In no refining situation that I was ever in would a bomb hitting a well anywhere in the world 'instantly' interrupt or even distress the supply. Most plants have more than a months worth of crude in the tank field and more in pumping stations. That yo-yo could play out over days, weeks and maybe months and have zero impact on plant operations. How many times has this been off and on in the last few months? These people and not stupid. These plants measure down time in hundreds of thousands of dollars per day. They are not sucking fumes or waiting on the next truckload with baited breath. Besides, as I noted, they are for the most part 'vertically integrated'. They own it from the dirt is sits in to the delivery rack and sometimes to the pump. It has a HUGE shock absorber built in. When production suffers, refining wins and when refining is winning exploration is killing. The rest of that crap in the news is a 'news cycle'. Government dipping in to reserves? Oil is stealing their milk money. There's a reason Chevron abandon Venezuela infrastructure and it had nothing to do with security of US citizens. Nationals run those plants. it has to do with MARGINS disappearing to corruption. They are in no hurry to return. Is there supply there? Oh yea. More than enough to offset what is bought in the middle east. Just isn't ???? Profitable.    We have supply. There are places in Illinois you can drive a pipe into the ground and run your homes natural gas furnace on it.    A refinery fire will gum up the supply works but not a localized war where the market is using a limited supply from. Now Europe, that's something other....
