I need some input here. I have a 2006 Chevy impala 3.8L V6. It has about 140K miles on it. Lately, I have been driving it longer distances than I am used to (60-90 miles one way). The last couple of times I have noticed a couple of things. First, it shifts really hard. I have to manually shift it by lifting my foot off of the gas and putting it back down. The RPMs usually stay around 1800-2000. Sometimes, about 40-50 miles into the trip, the RPMs will jump to around 2500-2800 and the temp starts to creep up slightly, but never into the red. When I come to a red light or a stop sign, the brakes like to have a little more pressure than normal to stop fully. Then, I come to a stop and put the car into park, the RPMs jump to 3000. I generally let it sit for a few hours before I try to crank it, but when I do, I have to pump the gas a few times to get it to start, but it always starts back up. I am going to be making some repairs to the car in a few weeks and I was hoping to address these issues as well. Thanks. ---

Is the check engine light on? Has the trans fluid ever been changed? How does the fluid look if you wipe the trans fluid on a white paper towel? Does it smell burnt? Is is bright red or dark? ---

Curious , what repairs are you going to make ? Are you doing this yourself ? If not then having a shop look this thing over for about 100.00 to 150.00 might help you decide to have everything fixed or just bail and replace the vehicle. It sounds like a transmission is needed at the very least. ---

I’m afraid you might have an expensive transmission repair coming up here. I suggest not making any other repairs until everything is fully diagnosed and you have an estimate, as it might not be worth fixing this car. ---

I am replacing the valve cover gasket and all of the tie rods. ---

The check engine light is not on. I have had the car for 3 years (it was given to me) and I have never changed the fluids, other than the oil of course. I know that the person who had it before me cared for this car with kit gloves. I will go out and look at the transmission fluid when it stops raining and report back here. ---

Wow… I hope you are wrong. That would not be preferable. I have done some reading and some sites suggest that there might be a vacuum leak. That is the circumstance that I am hoping for. ---

Sounds more like rearranging the deck chairs on the Titanic. As @VOLVO_V70 suggests,get you transmission looked at first. ---

Have someone try cleaning the electronic throttle body to see if that helps. Tester ---

I checked the transmission fluid and it is a dark red, almost burgundy color. While I had the hood up, I noticed that the upper radiator hose was collapsed. This may explain a lot of what is happening. ---

You might make it better with a trans fluid and filter change. At the very least, dropping the pan will show you how much trash has is in the pan. A rebuilt trans may be in order. ---

The cooling system cap is not venting properly and the coolant level may be very low, how is the coolant level? ---

My best guess if the upper radiator hose is collapsing you have restricted flow somewhere after the water pump. ---

My buddy tells me that I should flush the coolant system and the transmission. Would you concur? ---

I would not make a leap to transmission fluid for the cause, but it may be time for service on that also.
