The Mercedes-Benz 5G-Tronic (also called 722.6) is an electronically shifted 5-speed overdrive automatic transmission with torque converter lockup that replaced the older 722.5 5-speed hydraulic transmission and most of the 4-speed 4G-Tronic transmissions. It is in the process of being replaced by the Mercedes Benz 7G-Tronic 722.9 transmission which was introduced in 2003.
However, all V12-powered cars such as the S600 and S65 AMG still retain the 5G-Tronic, which has a torque capacity of 796 lb-ft, as the newer 7G-Tronic is limited to 542 lb-ft. Also, while rear-wheel drive W211 E-Class cars have adapted the 7G-Tronic, those with 4Matic retain the five-speed automatic, although the current generation W212 E-Class released for the 2010 model year has dropped the 5G-Tronic entirely, except for four-cylinder models. In Chrysler applications this transmission is also called New Automatic Gearbox Generation One, or NAG1.
Common Problems with the 722.6
Slipping, Erratic Shifting, Harsh Forward or Reverse Gear Engagement: Some of the most common 722.6 transmission problems are slipping between gears, erratic up or down shifts, or a hard slam when the 722.6 transmission engages Drive or Reverse. There are a number of design flaws in this transmission, and any one of them could be causing these symptoms.
Another common problem is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot.
Updates to Remanufactured 722.6 Transmissions
- Remanufactured pump, with new line bore bushings to eliminate leaks and provide superior flow and durability.
- Remanufactured valve body, with complete system correction and recalibration kit, improves pressure control and shift quality.
- Remanufactured and improved torque converter tested for leaks, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
- All new, bushings installed in key locations to improve internal fluid flow control and fluid pressures.
- Complete system correction and recalibration kit installed to address several OE flaws. Modifications include updates to servos, the PR system, and valve body accumulators.
- Heavy-duty recalibration kit installed to reduce slippage and increase durability.
- Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.
How to Buy a Remanufactured 722.6 Transmission
1) Buying Locally
When you go to your local repair shop, they’ll order a remanufactured 722.6 transmission, then mark up the price. So at the end of the day, you’ll be paying 15% to 30% more than the actual cost of the unit.
2) Buying Online
Buying a reman transmission through a company like Street Smart Transmission will save you a considerable amount of money because you pay the wholesale price (avoiding a repair shop’s 15% to 30% markup), they’ll ship the unit to the shop of your choice free of charge, and returning your old transmission is free as well. Then all you have to pay for is the labor to install the unit (usually $400 to $800), and you’re on your way.
How Does it Work?
To order a remanufactured 722.6 transmission from a company like Street Smart Transmission, all you need to do is provide your vehicle’s VIN number, the mileage, and the address of the repair shop that you want it shipped to.
Replacing a transmission can be expensive, so Street Smart Transmission offers financing through PayPal Credit. Depending on your credit, you’ll be able to order a new transmission, get back on the road, then pay for it over time. You may have to pay labor charges for the installation up front, but you won’t have to shell out for the transmission all at once.
When it comes to shipping, a transmission is quite heavy. So you’re going to pay quite a bit of money, unless the reman transmission company offers free shipping. Street Smart offers free shipping to a business address, which is usually the repair shop that you’ve chosen to install the unit.
What is a Core Charge (Core Deposit)?
Every remanufactured transmission originally came from somebody else’s car. Therefore, they need your broken transmission in order to refurbish it for another customer.
Your old/damaged transmission is called a “core”, and many companies will collect a core charge (usually $500 to $1500), which will be refunded once they receive your old transmission. (Street Smart does not charge an up-front core charge.) Make sure to ask any company for their core return policy, so you’ll know what to expect.
We recommend Street Smart Transmission. We have found Street Smart to be of the highest quality. Their transmissions carry a 3 year / unlimited miles warranty that covers both parts and labor. Their warranty is nationwide and attached to the VIN so it is transferable with ownership if you decide to sell the vehicle. It also covers both parts and labor for the installation of the replacement transmission.
