TCU question
I just had my tranny fluid changed today(at the delayership). about a mile down the road, I am stopped at a light, when accelerating 1st to 2nd BIG JOLT going into 2nd. felt it again later in the day 2nd to 3rd under average accel. Point Being, is there a re-training period of the TCU?
I have put about 90 miles on it since without a slip or wander.
or
should I be going back to the dealer with a big old, WTFDYD?

(Shaking finger like Babu from Sienfeld)
Low fluid level is very,very bad, man.
Find out how much fluid they put back in.
Did they list how many liters they used on your invoice?
A big ol' WTFDYD would be very appropriate here!

ATF level check
The ATF level is correct if, at an ATF temperature of 30-45C (86-113F) 1), there is still a slight escape of fluid through the filler plug hole,(the oil rises when it is heated).
1) For hot regions: 50C (122F)
Test requirements
Transmission not in "mechanical backup" mode
ATF temperature no higher than 40C (104F) at start of testing
Selector lever in "P" position
Engine running at idle (closed throttle position)
A/C and heat off
Vehicle standing on level ground
The ATF level is OK if:
There is a slight escape of fluid through the filler plug hole at an ATF temperature of 30-45C. 1)
1) For hot regions: 50C
- Install ATF filler plug.
Tightening torque: 80 Nm (59 ft lb)
ATF must be added if:
ATF does not escape through the hole for the ATF filler plug, even though the correct ATF temperature (approx. 40C) has been reached.
- Add ATF until excess ATF escapes through hole for ATF filler plug.

The info is from the Bentley CD.
