Tranny my tranny kinda hits hard while going from a stop once in a while it does that help me

sounds like your torque converter going bad. change the tranny fluid, and look for metal shavings (have a pro do this), sometimes you can squeeze enough life out of a bad tranny/torque converter by changing the fluid, or it might just be a clogged tranny filter. change the fluid, and if theres metal shavings in it, sell it while it still runs.

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.

Well no metal shavings should be in the filter if there is there is,something is not right internally in your transmission.When there is larger metal shavings in your tranny filter your tranny is probabley gonna have to be rebuilt or replaced.You can try changing the fluid and filter and see if that helps but nore than likely you will need to change out tranny with a new or rebuilt one.

I HAVE A 1989 F150 4X4 WITH 5.0 LITER AND A 5 SPEED TRANNY AND ALL THE SUDDEN THE SHIFTER STARTS FEELING LIKE ITS NOT WANTING TO GO INTO GEARS PROPERLY AND ITS HITTING THE DASH NOW WHEN I TRY TO PUT IT IN FIRST GEAR AND 5TH GEAR IS KINDA SWIRLY FEELING ALSO WHATS WRONG WITH THIS TRUCK ANYONE KNOW WHERE TO BEGIN WITH THE REPAIR OF THIS TRANNY

Inspect the brakes first, Then If this vehicle has a LOOOOOT of miles change the rear differential fluid, The clutchs in the rear end may be grabbing/slipping
This is actuallly my first suspect.

About 3 months ago, during my 25-mile commute to the ambulance base where I volunteer, my transmission started acting up. After a few minutes of driving normally, it started to upshift very hard. Each upshift was accompanied by a noticeable "Bang!" and it felt like the car was hitting a pot hole.

I immediately stopped and checked the tranny fluid at a service station, but the fluid level was fine and it didn't have any burnt smell. The car has 76K miles on it and the transmission fluid was changed at 50K per the maintenance schedule. I had no choice but to continue on to the base, driving very gently.

I made a stop about 5 minutes before arriving, to pick up dry cleaning. I was in the cleaners for about 8 minutes, and when I came out the hard shifting had completely disappeared. The car drove smoothly for the next 3 months.

Now, this problem seems to recur any time I drive the car even remotely hard. We're not talking about full-throttle accelerations here, since my everyday driving stays below 2500 RPM to save on gas. But if I'm in a hurry and start driving a touch harder - crossing over 3500 RPM - then the tranny will start shifting hard within minutes. Let it sit for 10 minutes with the engine off, and the problem is gone again

Have the diagnosis performed by certified transmission shop. Possibly bad solenoid in transmission.

sounds like your low on fluid or the powersteering pump is going out

It sounds like a tranny problem. Without more info kinda hard to diagnose. The simplist thing to check is tranny fluid. If its low, going up a hill will pull fluid out of the torque converter. It could be the converter itself. It could possibly a fuel problem, but unlikely. Hope this helps. John...

Someone may have put a rebuilt cv joint in and it is not any good
