They fit perfectly. I wish Connecticut didn't use so much salt on the roads.

The fit on these lines wasnt correct. I had to exaggerate some of the bends to make it work. Also, the rubber hose section inst near the quality of oem. I would buy from the dealer if I had to do it again.

Was able to install using floor jack and no lift with a bit of time/diligence. Clips in rusty fittings are as much a challenge as anything else. Can't speak for durability of crimps (at hose/tube transition) that I've read varying reviews on for different brands, but if you're not diesel, this is lower radiator to front trans line. Seems to be most commonly corroded. Fit was fine, slight change in one bend from OEM, but that's likely to accommodate a large range of years. Non issue. Figure 2-3 hrs dedicated time if you DIY. I read reviews about Dorman clips being too stiff, but it's really just putting those or originals back in same direction they came out, or they can snag and fight you. Can't vouch for lifespan, but assuming avg performance, it's a far superior upgrade to corroded lines that can fail and cost u a turbo 350 (4L60E). *Footnote - while replacing these trans lines, I noticed that my mild oil leak appears to be coming from oil cooler lines, also at replacement age. Makes sense as brake lines had failed in past 12 mos... Midwest winters and salt take a toll.

I tried to use this hose to replace a section I cut off of a transmission line, in order to remove my old radiator. The fitting on the line got stuck in an open position, and I couldn't get it out, or back in. I couldn't drive the car because it would leak. After putting the hose on with the new fitting that came in the kit, the fluid still runs from around both ends of the nut on the new fitting. Not sure what I did wrong, but this product didn't solve my problem.

They did not actually ahve teh kit when i got this so the erverice rep just made teh order up from bits off the shelf. The clips and hose was all the right size for my install on my 1995 legacy.
