Attention: TDR Forum Junkies 
going thru the torque converter locking and unlocking problem. have done the following: 1- tsb done by dealer 2- dtt filter installed 3- grounds cleaned 4- extra grounds added between ecm, pcm and neg. battery terminal 5- new apps installed and re-set , this was installed after 122 &121 codes. its been good for several days. however this am on way to work go several lock ,unlocks. this only seems to occur now while trans fluid is cold, once warmed after 5 or 6 miles doesnt occur again all day. been thinking about the thermistor locater in the governor pressure sensor. this is not suppose to allow 4th. gear when temps. are under 50 f. mine has never seemed to work since new, it has always gone into 4th. in colder weather. wondering if this could be my problem. anyone had simmilar problem ? thanks for any help.
