- 12, daily driver a hotted up Octavia 1.9tdi (custom injectors, ARB, poly bushes, cupra wheels etc)
I have the E class bible and manual but they have very little info on the auto box. According to the bible the torque converter has a 98% efficiency as full working speed (I guess approx 3k revs) but no mention of a lock up clutch. In the Ford, GM, ZF (BMW/Peugeot/Range Rover) they all have a clutch in the torque converter to lock the flywheel to the gearbox eliminating the torque converter once the car is rolling in 3rd/4th gear. This has great advantages in power and economy and lowers the revs of the engine. I can't believe with the price of the car that MB didn't have a similar system, do you all notice if your cars on the open road are 'locked' to the rear wheels ie take your foot off the throttle and the revs don't alter? Anyone know the tech specs of these boxes and if they have a converter clutch or similar system? Also any differences between the 300/24v box and the later 320 engine's box - I hear it starts in first, maybe it also has a converter lock up?
