Does somebody have a sugestion to this problem:
Engine V8-281Ci/4.6 litre SOHC fuel injected,transmission 4R/70W full electronic automatic with overdrive. At speed of 30 to 45 miles and touching very lightly the throttle, the transmission started to shake (hesitiating) for one or two seconds. Total millage of the 50.000 mile. Overdrive in or out does not make a difference. The car has been inspected by a so called Transmission "specelist" in The Netherlands. Problem still the same.

try changing the trans. fluid, including the torque converter. There is a rubber plug in the bottom of the bell housing. Remove plug and turn over the engine to gain access to the converter drain plug. Have about 14 qts. of fluid on hand. Good luck

Prepare for a trans rebuild.

this is typical of the old mercon dex 3 in the 4r70w , you need to have the trans flushed and refilled with either mercon5 mercon sp or the latest and greatest mercon lv . this was a typical issue , and the flushing with the newer fluid seems to cure most of it . other wise a new torque converter is in order . justin
