2003 Chevrolet Impala transmission non-smooth shift

I have a 2003 Chevrolet Impala with 96,000 miles. About 6 months ago towards the end of a 250 mile drive I noticed the transmission not shifting smoothly. Recently the problem is intermittent (never when the engine is cold). My mechanic drove the car with me in the passenger seat and said that this was normal. I have had the transmission fluid flushed at 30,000 mile intervals. The problem persists even after recently having the transmission fluid flushed. Is this normal? Would the "check engine" light come on if there was a problem?

    I am having the same problem. I had it diagnosed as code P1811, Pressure control solenoid. Said it was about and $800 job plus $180 to flush out the transmission fluid. It appears they have to take the transmission 1/2 way out and drop the pan. Not sure if it works as I haven't had it done yet. If anyone has any solution as to a cheaper way, do tell.....

I have a 2003 Chevrolet suburban when I start it up the transmission shifts smoothly but once I drive about 50 miles or more the tranny starts to slip please help


If the vehicle has more than 90,000 miles on it the transmission should be rebuilt. Chevy used the 4l60E transmission in Suburbans and it is not quite strong enough.A good rebuild will change all clutchs and plates along with the sun gear and cage.Also all electronic modules.I had mine rebuilt at 125,000 and afterwards pu an additional 200,000 on it without any slippage.

Could i be getting the 2-3 shift solenoid code if i havent changed the fluid in it or filter i got it at 96,000 miles and now it has 146,000 miles.1996 cavalier 2.4


It's very possible. Crud builds up over time due to the heat in the transmission. A fluid flush and filter change is a good idea. You may end up doing it twice - automatic transmission fluid is a great detergent and new fluid may dislodge crud inside the transmission, which will fill the new filter and clog it. Swap it out a second time and you're golden.

Did you have it serviced or rebuilt, If you had it rebuilt I would take it back to the trans shop for warranty repairs.
If they just changed the trans filter I don't think it would cause your problem.You just have bad luck with the slipping trans
