The 722.9's are the 7-speed 2006 trannies...

1) benz has gotten rid of the transmission fill tube.

2) although it shifts smooth as hell... ive replaced three valve bodies alone

3) the software has been updated twice

4) ive had two with mechanical issues... and benz wont replace them anymore, they want us to crack them open and replace broken speed rings and missing clips. NOT FUN

5) there CRAP

give them two years, then they'll be worth something... of corse thats right around when benz plans to unleash there camless motors in the W204's
