The frustrated owner of a 1996 Mercedes S500 called to complain that his vehicle had been acting up for some time and he was at his wits end. Apparently, he and others had taken a swipe at repairing the problem with little success so the vehicle was towed into the shop to get a look with a fresh pair of eyes, so to speak.
A 2006 Chrysler 300 AWD came into our shop with a shudder concern. The vehicle was equipped with a 5.7-liter hemi engine coupled with a Mercedes 722.6 transmission, and it had 84,751 miles on the clock. The customer brought it to us for a second opinion. Prior to the visit to our shop, the customer had taken the vehicle to a Chrysler dealer for evaluation. The dealer had diagnosed the problem and determined that a torque-converter replacement was in order.
If you have had the opportunity to work on a 62TE transmission, you may have noticed nine checkballs in tapered pockets that are held into place with C clips (Figure 1). In our seminars we explained that these balls are used during an assembly-line check with a special tool that pressurizes their respective circuits. Once the tool is removed these balls become plugs. Apparently this procedure was more economical when compared with the cost of providing typical pressure taps. But what this means to you is that these balls must be checked to ensure that they are in their location and that they are sealing. Otherwise you could be fighting a variety of different complaints.
Capillary action is defined as the movement of a liquid within the spaces of a porous material due to the forces of adhesion, cohesion and surface tension. A simple example would be dipping a paper towel into a glass of water and watching it climb up the towel. If the towel is long enough, eventually the force of gravity will be too great for the water to overcome.
Mercedes has used the 722.6 transmission in a number of different vehicles and in combination with different engines. To accommodate these different vehicle and engine combinations, different converters were needed. Many of the converters were similar in appearance and differed only in their bolt circle or diameter.
