Weird , weird ,weird.

Yesterday morning I start the car (75F temperature outside) and the trany was in a good mood.Shift was easy, rpm ok no more sluggish ups and downs.Drop my wife to work and on the way back home stop for a coffe.Half hour later while driving in slow traffic it started again : at around 15mph , while accelerating, I feel like it wanna change speeds and RPM goes up till 3500 and still nothing, than , i took my foot of the gas and then press again right away and it finally changes speeds.So I started to "help" the tranny from the gas pedal, accelarate , go to 2500 rpm , release the gas pedal and then press again and i could feel the trany changing really smooth. So far so good but its really annoying.I decided before I follow the leads ( Thank you DOC !) I would run it a couples of days more and see what patterns it follows.

Sooo, today ,start the car ,do the usual runnings and ......no more trany problems.Shifts ok, and rolls neat and good at around 1800-2000rpm( 40mph- 45mph) ,of course, under normal traffic conditions. WEIRD.

I will continue to log all behaviors and post back.
