Ok,so i bought a 05 impala with a 3.4 v6 about 3 months ago for $300,it had a blown engine but great interior and exterior.replaced engine with a low milage engine,and when i drove the car for the 1st time,i noticed that the car was stuck in 1st,FML.i let the vehicle idle for 3 min.. so the next day,i started my car let it warm up for 30 min and drove it.the trans took a little longer than your avrage shift time from 1st to 2nd but i got the trans to shift,oh yeah...after that senario,the trans shifted nice and smooth,but what ive started to notice is that the trans wont shift out of 1st gear if the vehicle is cold,it has to be in normal operating temperature or at least an extended idle for like 30 min to get her to shift.its killing me on gas cause ive been doi g my math and this problem with the trans is giving my mpg 11 avarage.
Ive changed the trans fluid and filter.
Theres no external leaks
And i bearly got a code,p1811.
FyI,i own a 04 impala ls and it has the same code but my trans does not act up like this 05 impala i bought.
shot in the dark ....but .... possiblytrans temp sensor....im a tech at a hyundai dealership and we have a trans that wont shift correctly sometimes due to fluid temp sensor. Try to look at a scantool and see if your fluid temp goes up...my $.002

No,it wont shift manually but what ive noticed is that if i dont warm it up like ive been doing,and i take off driving in 2nd gear,it wont shift from 1st to 2nd either but with in 15 seconds,it will eventually shift to nd gear and then ill just manually shift to the D mark in the cluster.that tells me theres something mechanical wrong.
Also i forgot to say that i hear a whine like a powersteering pump noise coming from the trans so im thinking that may be a pump thats about to fail or something.this noise may be tied to my issue.idk.
good point.ill look into it.
on that note,ive own this car for about 3 months and at the time i had a 04 3800 impala but unfortunately it got totalled so now im left with this base 3400 and i dont know if its the trans issue that im having now but man,this car feels slow/sluggish compared to the 3800.
