I have a 2006 chevy impala it has the 3500 v6 in it. I had the transmission rebuilt about 3 years ago. Of course warranty is out, but it is starting to slip. It was very bad. Wouldnt take off in drive. But you could shift from 1st, and then 2nd, and so on and it was drivable. I dropped the pan and changed the filter, and put some lucas oil stop slip in it, and it immediately helped. Just the first drive it was able to go in drive. It warmed up and started to slip a bit, but was still better. Im hoping it works better and better the longer the stop slip is in there.....but my question is. I have a 2005 Pontiac g6. It has the same 3500 engine as the impala. Will the transmission from the g6 work in the impala?
