2003 Chevrolet 2500HD 2WD 6.0L 4L80E
2003 Chevrolet 2500HD 2WD 6.0L 4L80E transmission. These lines were perfect, the kit came with both transmission inserts, the 4 90” bends needed for the lines to come out of the transmission and to attach up to the trans cooler. Used teflon tape around each attachment. So far no leak, lines were perfect length, not hard to install if you have the right wrench sizes. For my 2WD 4L80E transmission, the only products I used in the kit were: 2 70” lines 4 90 Degree bends 2 transmission inserts Had to buy seperate “ EVIL ENERGY 6AN Male to 3/8" Quick-Disconnect Female EFI Fuel Rail Fitting Aluminum 2PCS” to fit the lines to the trans cooler. Worked perfect though! Seam like good durable lines, fittings seem good quality, value for money is great. Update; one of the lines were leaking from the factory connection, sent me new lines and had priority shipping. Because of this, gonna leave at 5 stars!

Holds high pressure no problem
I got in a jam at 1am during a snow storm and blew the line on the lift cylinder on plow. Was able to use this line im a diesel mechanic and had no idea what line is rated for. This held alot of pressure no problem no leaks I believe its still onbthe truck.

Seemed good but didn’t use because of length.
Only 4 stars because the length didn’t work for my car. Other than that the quality seemed to be good and I like that it came with all the necessary connection pieces.

Braided transmission lines
This size fit perfectly well My 2000 mustang GT. You might have to zip tie it to make it to look neater but it fits.

Sent used parts, the wrong size aswell!! dont recommend buying for the following reasons
I ordered a 70 in kit it simply States it's a 70-in kit in the product title or the kit title the kit that showed up was a 76 in kit Which is far too long for the vehicle that I'm installing it on to make it worse it was a customer's car it was a time sensitive job and had to be done at a certain time that's why I went with this kit because I could get it ordered in a timely fashion however it is now cost me more and more time and more money than I care to even discuss however I'm going to as a buyer beware the kit that showed up Not only was it wrong in size however it was not in a state of what I would consider a NEW PART quality it had been prior installed or used prior by somebody and possibly returned it had transmission fluid on it the fittings were dirty as well as they were marred up from people using a wrench that was the wrong size the box that the product came in was such a small package for the amount of items in the package that they had Twisted the braided steel line in such a tight circumference of a circle that it was actually thinking the line in spots causing even further issues with the quality of the product and that being stated the quality of the stainless steel line and interior flexible PEX line is a very low quality the swivel fittings themselves are also low quality and then to continue with the quality issue the fittings that come with the kit to be able to adapt to different radiators and or Cooling cooling style systems and Transmissions were also very low quality with some of the threads needing to be cleaned up before they could actually be installed into the transmission as well as the radiator that we're both in New Quality and new condition however these fittings wouldn't thread in easily and it was due to the poor quality of the fitting manufacturer AND THE THREADS HAD TO BE CHASED TO MAKE THEM USE ABLE. So the customers car wasnt done onetime. I had to get my local fittings and hose building supply house to do an after hours service for me however there hoses were exactly as I asked and exactly what they promised and of far greater quality craftsmanship and attention to detail that even with an after hours fee makes the locally built hose's the way to go. I have really been trying to offer my customers more competitive pricing and been giving Amazon and its sellers a chance to fulfill as many parts and materials as I need aslong as there quality and reliability is of high enough standard to compete with my normal suppliers. But quslity and reliability have and will always be my first priority. These hoses in my experience have been far from eaither of any acceptable level of quality and I cant imagine in such low quality there could possibly be any argument made that there reliable in any way. There are however dozens of other suppliers of these kits from other manufacturers available on Amazon so keep shopping. I WOULDN'T BUY THIS KIT AGAIN!!!
