Testing transmission delay upshift sensors and electronics?

If it is not the tranny itself, which we seem to have ruled out based on the rebuild and the above discussion, how does one test the sensors and the controlling electronics to see if there is a problem with their operation?

I can see the little black delay upshift unit that is attached to the driver's side of the tranny. It has a single cable that comes up to the area under the air filter. (1990 300SL) ... and it is way on down there...I will need thin arms or have to get to it from underneath.

Many thanks...

'90 300SL
'90 190E 2.6
'87 300TE (gone to car heaven)
'84 190D (passed along...still in the family and used on a daily basis)
