2006-2009 5/8" allison transmission cooler hose set #50300

  • By:
    After tiring of the continual leaking of the factory transmission cooler lines on my 07 2500HD GMC Duramax, I spotted these 1/2" hoses online and decided to give them a shot. This has turned out to be an outstanding decision. They perform exceptional in both extreme heat & cold; 6 months and 20,000 kilometres later and the hoses and all fittings are dry as a bone. About 6.000 of those kilometres were heavy towing, to Arizona and back, and no problems. My mechanic who performed the install was so impressed he asked me for the info where I got these high quality hoses from. Well done Red's, these are a top quality solution at an excellent price!

    This is the best solution to a problem that GM has failed to resolve. After seeing both the 1/2", and 5/8" hose sets, I would definitely go with the 5/8" set. The 5/8" sets use quality Gates hoses and fittings, where the 1/2" set uses a generic hose.

    I had bought a 2006 duramax in june of 2009 the short hose from the radiator to the cooler was leaking had the dealership replace them before I took possession of the truck. 3 months later the same line was leaking again (thanks GM). After alot of searching and talking with the best GM diesel mechanic in the area I decided to go with the 5/8s Reds Auto Rehab set. I ordered them on a Wednesday afternoon had them sent USPS and still received them by the following Monday. When they got here and I had inspected them im sure I will have no leaking lines. Heavy, solid, good quality hoses and fittings. After you get the bumper, grill, air box brackets, intercooler down pipe and the rest of the plastic out of the way the install of the lines were very easy. The directions Reds supply with their line sets are very good and very detailed. One thing I can tell you is when you route these lines where the olds ones were its a tight area. When you get them in place make sure they aren't drooping down to where the bolt on the steering stabalizer can cut into them when you turn ur wheels. With 2 people this was about a 2 hour install. For the same price as merchant preformance or all season diesel filler pieces, why not go w new lines all together with heavier lines? Thanks for the great quality product Reds.

    After years and years of dealing with leaky factory tranny lines, and wasted expensive amsoil in my driveway, I finally found a cure! These lines are top quality, and the instructions are very well done. No more red fluid in my driveway! 2 hours to install and about 2 qts of fluid lost. Thanks again for a great product, at a great price! Highly recommended!

    I bought these hoses after reading on many forums that the GM factory hoses were just as bad as the originals.

    These are a much better replacement, and the craft work is excellent.

    Took a few hours to install, and work great.

    I went with the larger size due to the pulling I do.

    Shipping was fast too.

    Thanks, I will be sure to reccommend!
