Your fluid is either old or the wrong kind for your transmission. Changing your manual transmission fluid with a higher quality fluid should definitely reduce the difficulty of cold fluid/cold weather shifting. First go to the parts store and find out exactly what kind of fluid your transmission takes. Most manual transmission use gear oil. I recommend using something like Red Line, AMSOIL, or Royal Purple if available. A synthetic will make it even easier to shift. Always check with the manufacturer if you are unsure. I try to stick with the manufacturers recommendations because typically they know what works best with what they've engineered...but sometimes after market fluids can't be outperformed.

Engine oil for cold climates 5w-30. Warmer climates 10w-30. Any Auto-zone parts store person at the counter would be more than helpful choosing the correct fluids for your vehicle.

On every automatic transmission. you have whats called a tourque converter. If a flush and tranny fluid fill did not work before its not gonna work again. Your tourqe conver has gone bad or for some odd reason become detatched from the transmission housing. One thing that i know with all my experience you should never have your transmission flushed, especially more than once. Replacing your fluid is one thing but a tranny flush is just one thing auto manufactures should have never come up with. Also Check to see where the flush was done at. If it was done at a Jiffy lube, i doubt it was even done. BIG SCAM WITH JIFFY LUBE AND THERE TRANNY FLUSH SERVICE (check youtube for news reports). Now expect to pay a pretty penny for this becuase you have an automatic transmission. Normally on a manual, it would be your throwout bearing, but becuase the impala was never released with a manual tranny at least in that generation, your kinda stuck with taking it to a service shop. GO TO A GM SHOP. and ask them to fill the tranny with a special tranny fluit called DEXRON VI ONLY. Dexron is the only fluids that meets GM's standards.
