in newer Mercedes when it takes too long to shift it can be reprogrammed by the dealer

I was wondering if the RL has a feature to reprogram the transmission when it takes too long to shift

when I reverse and put it in drive it takes a while to shift and then it jumps if I slightly tap the gas so I don't do that

I have maxidas scanner that worked to recalibrate the traction control but I haven't looked into the transmission programming yet

 

Not sure if this is what you're looking for?

 

ALL modern car ECU's will learn driving habits!!
you can easily reset the ECU by disconnecting the negative battery terminal for a few seconds to a minute

unfortunately, the problem you are describing ISNT a ECU question...it's more of a transmission mechanical problem...
the best you can do is frequently drain and fill your tranny oil.
then you can change out the pressure switches, so that it may re-act quicker.

 

The Honda five-speed is incredibly dull-witted and slow to respond.

Both to RND-DNR shifts and the paddles, ignoring your inputs if it's recently shifted itself.

It's just something one has to live with...
