Hummer H3 transmission problems = Solved. So you get a transmission thatРІР‚в„ўs designed to outlast the original, and a warranty that covers you anywhere in the U.S.A.

Unlike most transmission warranties, our Nationwide Warranty will pay for parts and labor at any licensed repair shop in the country. It also allows us to issue a 3-year/Unlimited Mile Warranty (18-months/100,000 miles for commercial and heavy duty applications). That way there wonРІР‚в„ўt be anything out of adjustment once itРІР‚в„ўs installed. This ensures proper functionality, and breaks in all of the new components.

Not only is it upgraded to correct all of the factory design flaws, but it also has to undergo hot & cold dyno testing before it leaves the factory. To find a permanent solution to all your transmission problems, youРІР‚в„ўre going to need a remanufactured Hummer H3 4L60E transmission from Street Smart Transmission. Solution C: Buy a Remanufactured Hummer H3 4L60E Transmission But all of the factory design flaws will still be there, and that 1-2 year warranty might only be honored by a small number of shops. Most of the time, a mechanic or transmission shop will simply remove your existing gearbox, then use an OEM rebuild kit to replace most of the commonly worn parts. If you donРІР‚в„ўt want to risk having more 4L60E transmission problems in the future, then you could opt for a rebuilt Hummer H3 transmission. Solution B: Buy a Rebuilt Hummer H3 4L60E Transmission

And while youРІР‚в„ўll probably get a 30-90 day warranty from the salvage yard, itРІР‚в„ўll only cover a replacement transmission, not the labor cost to install it. Finding a used 4L60E transmission that doesnРІР‚в„ўt have any problems however, could be very difficult indeed. Since itРІР‚в„ўs based on a standard-issue Chevy pickup truck, finding a used Hummer H3 transmission at a junkyard wonРІР‚в„ўt be very difficult. Solution A: Buy a Used Hummer H3 4L60E Transmission

How to Solve Hummer H3 4L60E Transmission Problems To extend the service life of your Hummer H3 4L60E transmission, Street Smart Transmission installs an upgraded High Energy 4L60E 2-4 transmission band, which features a much thicker layer of friction material that adds to the durability and longevity of the transmission band and clutches. Over time, the OEM friction material on the transmission band can wear away, preventing it from engaging the clutch drum and shifting properly. This Hummer H3 transmission problem can be caused by a worn or broken 4L60E 2-4 transmission band. The opposite of the above problem is a long pause between 1st and 2nd gear. In order to keep your H3 4L60E functioning longer, Street Smart Transmission replaces the OE 1-2 accumulator pistons with stronger aluminum pistons, and completely recalibrates the valve body for better fluid pressure control. ItРІР‚в„ўs designed to act like a shock absorber, reducing the effects of the pressure that builds inside the valve body during a gear change. This issue is usually caused by a faulty little plastic piece called a 4L60E 1-2 accumulator. If youРІР‚в„ўre experiencing a harsh 1st-to-2nd shift, delayed 1st gear engagement, or a transmission shake/shudder at low speeds, then you have another one of the common Hummer H3 transmission problems. To correct this design flaw, every remanufactured Hummer H3 transmission from Street Smart Transmission is fitted with a more durable 7 disc High Energy 3-4 clutch pack, which is designed to significantly outlast the OEM 3-4 clutch pack. This happens because one or more of the metal clutch discs inside the 4L60E 3-4 clutch pack can fail prematurely and prevent the transmission from engaging those gears. One of the most common Hummer H3 transmission problems is the complete failure of 3rd and/or 4th gear. But time and mileage can lead to some common Hummer H3 transmission problems, which weРІР‚в„ўre going to look at now.Р”В¬ommon Problems with the Hummer H3 4L60E Transmission All three powerplants (3.5L, 3.7L & 5.3L) were backed by the 4-speed automatic 4L60E transmission, which was perfectly capable in this maxed-out SUV.

Part of this capability was due to the trick suspension/axle setup, and the other part was due to the stout 5-cylinder and V8 engines. Regardless of its underpinnings, the Hummer H3 could still wade through 2ft of water, climb over crazy obstacles, walk up moderately high walls, and park on top of small hatchbacks. So it was produced alongside the pair at GMРІР‚в„ўs truck plants in Louisiana, Canada, and South Africa. The smaller Hummer H3 however, was largely based on the Chevy Colorado/GMC Canyon. The legendary Hummer H1 continued to be built by AM General, as did the new truck-based Hummer H2. In an effort to expand its SUV portfolio, General Motors acquired the Hummer brand from AM General in 1999. Hummer H3 Transmission Problems & Solutions
