2001 shifting problem

My wife has 2001 , 4 door v6, with 130k, if its cold outside, or truck sits over night the first time she puts in drive Rpms go up but no power gets to wheels , its only in first gear, first shift after that its totally fine. Once it gets to second gear no problems, reverse is fine. If she stops truck goes shopping etc... comes back truck is still fine first gear no issues, its only first cold shift of the day....

We replaced transmission Filter last weekend and put Lucas trans fluid. Still happening. Dealer replaced filter at 60k I did it at 130k no metal shavings and fluid still looked good and clean when I did it. What should I look for now, wife has a feeling transmission is going to die on her I don't think its that bad, then again I don't want her to get stranded and then ill never hear the end of I told you it was going to die., I knew it was messed up.

 

i doubt there's a problem. i think its from being cold(tranny fluid).......mine does it as well.

 

Well I drove truck this morning it rpm @ 3500 before it shifted, I have been going by her word, it took awhile to get into second gear, but once it did it was just fine.. it felt like it bogged down I could have floored it this morning but still crawled up to speed before it shifted.it never did it till about 1 1/2 months ago. If u floor it u expect it to take off but not the 1st time, it shifts. We installed a remote start last year and my wife lets it warm up every day for about 5 minutes weather its hot or cold. So its not like its a jump in and take off like bat out of hell its warmed up.

 

Mine does the same thing. Shifts out of 2nd gear at 2700 in the mornings. I dont think its a huge problem. I dont have the bogging down effect though.

 

Mine does the same thing. I just take it easy for a few minutes until it warms up.
