tranny question

hey guys my 94 atx had the transmission rebuilt about 3 months ago, it shifts well but on the highway the converter seems like it doesnt want to lock and will go to 3K and then back to about 2,500 at about 70, it didnt do it that much but the past few days its been pretty cold at night when i go to work and it seem like when i first start driving it and get onto the highway it take like 2 miles before it locks, then it drives fine, what do you guys think?

typical - the torque converter will not lock until the trans temp sensor reads that the oil temp is at operating temperature.

so do you think everything is fine with it, is it just that its been colder its taking a littler longer for it to lock up, thanks
