A perception of a hard shift into to the drive or reverse gears can be due to a problem in the idle speed control system, the engine may not be fully warming up or doing so slowly, also excess play in the drive line can make this feel harsh, examples of the are a worn rear gear or bearings, this allows for excessive backlash in the differential and makes a clunk when shifted to drive or more often reverse being the worse of the two, have this done, have the drive-line checked for excessive play, this includes the transfer case (if 4 wheel drive) the universal joints and the backlash in the rear end gears, also have the transfer Case checked for a loose drive chain inside the case, there is a tool to check the play/slack in the chain, this can cause this harshness as well and is common "clunk" in 4X4's if all this checks ok have the engine idle speed control system tested and the engine cooling system thermostat checked to make sure the engine idle isn't stay a little to high due to a to cool running engine, this is very important, also have the system tested for active running problems, this is called a key on engine running quick test, a Ford/Lincioln dealer will need to do this test in most cases, all this can be very expensive, this slack that causes this noise will not get worse or will it cause a breakdown, left to me I would ignore it unless it is really bad, another thing that you can do is give the engine a few more seconds to slow down before engaging drive or reverse, I suspect reverse is the worst, this is what i have seen at the Ford dealer I have worked at for 25 years..

My car hesitates while shifting sometimes. when I hit the gas, my RPM's will go up, then they will usually drop right back down even if I am accellerating. sometimes, it doesn't even go into the right...

Much of the shifting in today's vehicles is done using various sensors and it seems some of them are off. You may need to take it to a shop for testing.

2004 Lincoln aviator goes into gear but won't move

bad transmission maybe. Try going into a lower gear (2 or 1) and giving it a little gas and holding it there. (about 2500 rpm) Hold it there for about 30 seconds.
If it still doesnt move, look under at the side of the transmission where the shifter cable connects and make sure it is moving.
Make sure the brake is on and the wheels are blocked and have a friend shift it back and forth while you look.
Sometimes, the connection pin comes out and you wont shift. .
If it does move right away, head to the transmission shop.

Hi i have a 2001 honda accord ex v6 coup. it had an automatic transmission when i put it in reverse it jerks really hard an shakes the car sometimes. when i put it in first gear it jerks the car alittle...

I suggest you have a transmission shop take a close look at your vehicle. That year accord with a v6 and automatic transmission had a recall for the transmission and your problem seems to be a slowly dying tranny.

Shifting issues with a 2003 dodge neon sxt

Here's what I found one my old 95' neon. On top of where the shifter linkage attaches to transmission is another half moon shaped (if i remember correctly) linkage that control the throttle valve operation, for kickdown etc for passing. Mine would seize up occasionally from the weather etc & it would hang in lower gear forever before shifting up, then shift down hard when stopping. It even made my gas pedal stiffer to push. It's hard to see it without removing some things out of the way on drivers side. Anyway, that little piece on top of shift linkage has to move very freely. When you get to it, spray it with lots of penetrating lube like WD-40 and shaft it sits on top of & keep working it by hand until you can move it all the way, both ways, easily. Then apply a good coat of white lithium grease or similar to keep it lubed up. I had to do mine about 3 times in 5 years. Give it a try & let me know. I do have a picture somewhere of what /where it is, so if your stuck or not sure, let me know and I'll see if I still have it.

Trans shifts very hard after 5 minutes of stop and go traffic

A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!

The floor shift to put automatic transmission in gear is loose.

you have to remove the console cover to get access to the bolts that hold the shift assembly to the floor. I think there are 4.

You probably have to remove the shift bezel cover (PRNDL), remove the shift knob to get the console off.
