#199 of 451 Transmission problem with 2004 Chevy Impala LS
Jul 05, 2010 (11:05 am)
I have a 2004 Chevy Impala LS with 109,800 miles. I bought the car in 2005 with 32000 miles. I have never had any problems with the vehicle until about 6 months ago. I took the vehicle in for an oil change and they suggested I have the automatic transmission flushed with this machine because the fluid was dirty. Ever since the flush the transmission has started slipping. When I first get in the vehicle it runs great for about 15 or 20 minutes. As it gets hotter the the transmission will jump in and out of gear while at high speed. If I come to a stop the transmission seems to clunk as is trys to downshift. The other day I was sitting at a light and the car lurched and died as though I popped the clutch without giving the vehicle any gas. Another thing if I drive the car 10 or 15 minutes, shut it down, and then try and restart it it will jump and die. When I finally get it running the transmission will jump in and out gear as though the computer doesn't know what gear to put it in. Any ideas from anyone would be greatly appreciated

Well your decision to power flush a high mileage transmission was regrettable. This is not a good thing to do in most cases.
You might scan the car's computer for transmission trouble codes and go from there. It's impossible to diagnose a modern electronic transmission from this distance.

One thing I forgot to mention. After driving the impala the last time I could not get the key out. The steering wheel will not lock to allow me to remove the key. I had to disconnect the battery to keep the battery from being drained. Any ideas on how to get the key out. Also I have an appt with a transmission place on Sat to get an idea of what is going on.

That's probably the Shift Interlock Solenoid in the steering column. Maybe it's defective or the fuse blew out. You might check all your fuses.

Yes you are exactly right. It was diagnosed that the catalytic converter was almost completely clogged up...Once it was replaced it drove like a brand new car!!!
#204 of 451 2003 3.8L Transmission Problem
Jul 07, 2010 (5:47 am)
Hello, over the last day or so I have been experiencing what I believe to be a transmission problem. It seems that when the car changes gear from 1 to 2 it would what I would call hard shift....also from 2 to 3 it does the same. It seems that 3 to 4 is OK and no problem while in 1st.
Any ideas what might be causing this problem?
I appreciate any help/suggestions!

#206 of 451 Removing transmission sidecover
Jul 17, 2010 (4:16 am)
I`m replacing two shift solenoids in my transmission. I know where they are located and how to replace them but a couple of things have me confused. Does anyone have step by step directions on how to go about getting the sidecover off completely, I was close but couldn`t get the axle to pry out. I think the previous instructions I had were incorrect on detailed instructions. I have a 2004 Impala with the 3.4L. It`s either this or I pay someone $650 to $2700 to tell me it`s shot and it`s not. Thanks!
#207 of 451 Transmission problem or not???
Jul 17, 2010 (2:19 pm)
I have a 2006 Chevy Impala LS and my car functions properly in drive, park and neutral but not reverse. When I put my vehicle in reverse it feels like I am in park (goes nowhere). I can still put my car in drive and my car is mobile. There is no signs of "slipping" or mysterious gear switching. When I put my car in reverse, I can hear it switch gears but I do not feel the "release". What is wrong with it any suggestions??? I heard it may be some type of contol box or sensor unit that may be out of whack that is not properly sending the signal to my car that my car is now in reverse....Any advice would be appreciated!!!!!!
