    • Leak
Review Image by jose luis jose luis
they seem of good quality I ordered a set for my 07 gmc allison transmission because my stock ones started to leak, I installed the new ones but a bad factory leak was leaking unfortunately I didn't have much luck getting them to replace just one, I already paid to install them and I did not want to pay back to remove them and return them to amazon, they did not give me very good customer service, I had a bad luck, it had a leak just in the transition from metal to plastic so when ordering them be aware of that ... show more

    • Fittings can take some adjusting to get sealed
Review Image by Chris Chris
09 sierra duramax 6.6. They fit well, plan for a cooler as the factory one crumbles taking the fittings out. Fittings can be frustrating to get sealed but if you spend a little time on them you can get them. Don't fill with coolant till after you are sure the radiator doesn't leak, I did this twice.. tighten and re loosen and tighten the "hose to fitting" connections a few times to get them to seal, basically seats them together. But after all the fighting I did to get 2 connections (lower radiator connection and right side of cooler) to seal this conversion made the job 10x easier as the factory hard lines would have been near impossible to install. For me the savings was worth the extra time adjusting things. Been in 3 days no leaks or problems. Time will tell how they hold up, if one blows ill take it to a local equipment shop and have them re make it ... show more

    • Fit my 2006 duramax with minor modifications
The kit comes with hydraulic style hoses and the proper fittings to connect to you transmission and transmission cooler. However they say to use the 45 degree fitting in the upper transmission port. This is physically impossible because the fitting cannot rotate without hitting the transmission case. I had to buy another kit and swap out for a straight fitting to get the job done. If it came with all the right fittings I would have given them 5 stars. ... show more

    • Good enough
Fit pretty good to replace old trans lines. Remember to do 1 line at a time when doing the radiator part or tank inside of it will fall to bottom

    • ATTN: Does not fit 2008 GMC 2500 Duramax
Do not buy these. The fittings are too small for the transmission and the transmission cooler. These will be going back. I was trying to save a couple of dollars, but you get what you pay for. Live and hopefully learn, lol.
