E230 W210 Trans issue (722.6)
Hi guys,
Minor issue with my 722.6 When starting cold, there is a delay is shifting. Reverse engages straight away. But rather, shifting from reverse to drive results in a 2 - 3 second delay. It can occur when hot, but rarerly. Results in me putting my foot down and not moving anywhere untill it engages. Fluid was changed about 13 000 km ago for the first time at 140 000 km. I planned to do a filter and fluid change but haven't got around to it yet. There is the occasional erratic gear change, but 99.9% of the time it drives great. No limp mode, etc. Any ideeas? |

That was an awfully long time for the first fluid change at 87,000 miles. Even though the 722.6 was ostensibly a lifetime fill, most people did fluid changes at 40,000.
Try another fluid change and check for any debris. |

Other than a slightly low fluid level...

Level
Fluid level is slightly over the maximum mark for 80C - about 5 mm above.
Fluid is clean (other than a very very slight brown tinge). Doesn't smell funny or anything like that. Is it advisable to correct the level with such a minimal overfill ? Could this be my issue ? |

The 722.6xx is VERY sensitive to fluid level. Drain some out until you get to the 80 degree band on the dipstick tool. Each tick mark on the tool is 0.1 liters so you are about 0.5 liters overfilled.
Did you use factory spec ATF? Brown color is normal as the red fades after a few thousand miles.
