722 Automatic transmission information
722 Automatic transmission information
(09-09-2010, 03:38 AM)majesty78 I´ve talked to an MB Transmission technican today, and must say, that the information posted here is unfortunately false.Hi,sorry for my english,I'm automatic transmission rebuilder and mercedes fanatic.Alex,sorry but your technician is no very good.722.5 never was coupled with V12 only 722.3 and 722.6 .722.5 is no 722.4 with OD,but 722.3 with electronicaly aktivated OD,like chrysler transmissions.Most problems in 722.5 is OD,it is cause why rated torque for 722.5 is smaller when for 722.3. The 722.3 is very best transmission in mercedes,if this transmission was with 6.0 v12 and 7.2 v12 it can handle much power.this year in my shop was an W140 7.2 Koenig all internals frictions,steel,bands,planetary was standart,not tuning ,but this engine is
The torque which those trannys can handle is NOT validated through the last 2 numbers of the W5A/B... numbers.
There are so many different variances of all aof those transmissions, like 722.1/2/3/4/5/6xx which all have different torque ratings.
So there are per example 722.5 transmissions which are rated up to 1080Nm coming in the 12Cylinder AMG engines, and 722.9 transmissions rated up to 735Nm.
The 722.4 per example is an fully hydraulic actuated transmission (besides 2 soleniods), with brake bands, 722.5 is actually an 722.4 but extended with an 5th gear which is electronically controlled. 722.6 is fully electronic controlled without brake bands but friction discs.
722.623 has per example the above stated 580Nm torque handling capacity, but there are also 722.6xx transmissions rated to only 330Nm...
