I have an 03 impala 3.8 with 160k on it. shortly after i bought it at around 140k the trans started acting up. i drive 92 miles round trip a day and here is what it is doing
1. if i pull away from a light at a very slow speed it shifts to 2nd fine, if i pull away from a light and accelerate harder than normal it will shift into 2nd around 33mph, but if i pull away from a light at a normal pace it wont shift to 2nd and in fact it gets in between gears and goes into a neutral state. I rev the engine a little and it will shift to second. I dont get any slippage even if i floor it. when its cold it shifts fine until it warms up then it does what i just explained. I did change the fluid and filter around the 140k mark and just did a flush with 2 gallons of fresh fluid while i had the lower line off and plumbed into a bucket. Yes the fluid looked pretty dirty. any ideas i should try. thanks.
