[W126 Coupe] Transmission Shift Question

[Dick Spellman]

To help me sort out exactly what is going on with the shifting on a 126 
transmission (gas engine) I thought I'd post the symptoms and see what 
any of you in the know think about what I am dealing with.

This car has the Economy and Sport switch on the shift gate and it works 
fine in sport (first gear start) but I routinely run it in Economy 
(second gear start) for fuel savings.

So, when starting out and accelerating I get smooth shifts with a small 
amount of flaring between 2nd and 3rd and a smooth firm shift from 3rd 
to 4th.  So, I'd say this is all within acceptable limits when compared 
to the other 126 chassis MB's I drive.  Here is the problem, when I am 
slowing down to say make a stop at a red light and the car is still 
doing 5-10mph and the light turns green and I go from brakes to gas, 
there is this long flair (pause) and then the car shifts fairly hard 
into 3rd.

Questions does this sound like the modulator or the B2 piston having a 
problem?  Regards,

Dick
