Transmission Not Shifting?

Hello,

Did you switch the Transmission Speed Sensor (TSS) when you switched the transmission. The Transmission Control Module (TCM) uses this information the figure out when to shift, without it it sounds to me like it is "limp mode". I have included a link for you to go to down below:

and

I have also included in the diagrams down below a voltage pinout chart for your TCM. It will give you what the expected voltage should be at every pin in the connectors that go to the TCM so you can make sure your new transmission is working as it should. Please get back to us and let us know what you find out.

Thanks,

Hello this is Jack Russell. I wanted to tell you how much I appreciate you sending me those diagrams and testing pinpoints. I was able to trace it down to a multi-plug on the solenoid B valve and without your help I would have never been able to do it. thank you so much you are absolutely the best.

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Transmission problem
2001 Honda Accord 4 cyl Front Wheel Drive Automatic

My car is starting to have problems shifting out of park. It takes several tries on pressing on the bracke before the push button on the shifter allow you to shift ot of park. How do i get this fix and can i do this at home or do i have to bring it into a dealer?

If it doesn't shift out of park, press the brake pedal and check your brake lights. If the brake lights doesn't work when you press the brake pedal it's a faulty brake light switch.

After I start the engine, sometime I cannot press the gear lever to put the car into reverse or drive gear. Sometime I have to apply the brake several time before I can press the gear lever and put my car into reverse or drive gear. Other time, I have to turn off the engine and restart the engine before I can press the gear lever so I can put the lever into reverse or drive gear. It seem like the brake system is not enganging or maybe it is the transmission, who knows.

It could be a faulty brake light switch, try to check the brakes lights when its not shifting out of park when applying the brakes. If the brake lights does not come on when the brake pedal is applied, its the brake light switch.

My car just started not wanting to shift gears correctly and when it finally does shift it's a real hard shift. Checked the fluid it's good. I am a female and I know a little about vehicle mechanics but not a lot. Where do I need to start to figure out what might be causing this? Thank you so very much for your help.

Hello,

This is common when the input shaft speed sensor goes out. To be sure lets run the codes. here is a guide to help you with the repair and a video (similar car) to show you how if the sensor proves to be bad:

I had an accident recently where my car,a honda accord v6 shaft pulled off the gear box.my local then changed the Ball joint and proceeded to return the car to me but on his way, the car stopped moving.we discovered there are no more gear oil, new gear oil was filled but the D4 & D3 gears could no longer select.only gears 1 & 2 could move the car...suggestions locally are that the car gear Sensor should b changed...am confused, pls advise, iv not changed d sensor or will it be that the car gear has packed up?
Again, if changing gear is the solution, can you help me with any online gear selling company i can order a genuine replaceable gear?

Check the transmission fluid, just to be absolutely sure that the fluid level is correct.

Next, you'll have to take the car to a transmission shop to have them check (scan) your computer for codes. These codes (if there are any) will get us started in the proper direction for diagnosing your problem. Post the codes here, but do not purchase any services or parts until we've had time to advise further.

Also, look at the end of the axle where it goes into the transmission/transaxle to see if it fits completey into the transmission.
The mechanic should also change the axle seal on the affected side of the transmission (to prevent fluid from leaking out in the future).

I drive a Honda Accord, model year 2000.

My problem occurs when I go up a hill and accelerate with the gas pedal. The RPM's crank up, but I'm not going any faster. In fact, it feels like I'm in neutral when I'm actually in gear.

I'm not changing gears when I do this either. Is this a clutch problem where the car is slipping out of gear? Could I be low on clutch fluid?

Scott Rubens

It sounds like you clutch is gone. If the clutch fluid of sleeve cylinder was the problem you would have a hard time shifting the gears not slipping out of gear.

I bought the car back in August and it has been doing just fine. I live in south and we just had some temps down in the low 30's. On those mornings the car would not shift through the gears smoothly. The engine would rev. up and down tring to go into gear. It would finally make into 3rd and after the engine came up to temp. it would go into 4th. It will do fine the rest of the day and on the way home when the temp. got into the 60's. Is there anything I can do with out taking it to a repair shop?

try having the transmission flushed and the filter changed. It might have a little sludge.

FYI..... Transmissions had a birth defect from the factory on model years 98-02, warranty is extended to 105K on these model years. I had the same issues you are experiencing, I flushed the fluid it helped for 2 months then the problem got worse. You need to bring it to Honda and inform them of the issue. I brought mine in and they told me to flush the fluid again, I told them no. I let them know I was aware of the transmission problems on these model years and would not settle for anything less than a new transmission. I got a new tranny and its runs fine.

The vehicle only can go reverse and will still go forward only when engine is cold. only when the engine get hot it will not go forward.

Sounds as if the transmission is slipping badly. can you check the transmission oil? f it is burnt and smells this is a sure sine the transmission is slipping. if so it will be a major rebuild or replacement transmission required to fix this problem.

My 2000 Honda Accord will not shift out of park, I don't hear the click when I depress my brakes. I appreciate any help!

Hi Damigotit,

Check if the brake lisght are working when pedal is depressed.

It could be a blown fuse or a faulty brake switch.

Occasionally when I first start my car and I push on the brake to place the car into gear the button doesnt always engage. This is a pretty inconsistant happening but I dont know if I should get it checked out or not

Hi nursegirl,

If the gear shift sticks in park, either the brake switch is not working or the interlock solenoid is not functioning properly.

I wuld suggest checking it out as you might be driving without brake lights if the switch is the cause of the problem.

hi, i recently had my tranny rebuild but instead of using the honda transmission fluid atf-z1, i used a dextron3 transmission fluid because it was readily available. i am now experiencing some extramely harsh shifting from 1st to 2nd gear and also some slight delay in shifting. does this mean i would have 2 get my tranny repaired again? or should i just change my fluid? what shall i do?

On my Honda accord transmission was replaced by Honda there was a recall.

Have it flushed and put the correct fluid in it. Hondas are very tempermental to teh type of fluid used in them

My 2000 Acoord is giving me some sort of tranny (shifting) problems. When the car warms up the tranny starts slipping (rpm's go up but the vehicle hardly moves and then finally the gear kick in). I checked the fluid level and it doesn't show it needs oil nor it smells like burned or no showing of metal shavings. one mechanic told me it seems to be a the tranny solenoind. Is this possible?

Hi moreno928,

Yes, it could be a faulty solenoid of the transmission itself. Get a free scan done at Autozone to check if any trouble codes are stored ini the PCM and let meknow if any found.

I was driving one night my car d4 light started blinking then it would not shift anymore. I need some help. I try draining the ATF and put some Lucas. That did not work. I tried solenoid switch, I test it it is working fine. need some advice.

Get it scanned with a good scan tool. The light will have set codes that can point you toward the problem. Without them you are flying blind.

I just bought a 2001 accord lx v6 from a good friend who was the only owner and took great care of the car. Though buying from a friend, I still took it to a mechanic who said it is in "excellent" condition. He said I should have the transmission fluid changed in the next 5k-8k miles.

Yesterday I noticed a couple of times that as I slowed down you could feel the transmission downshift at about 5-15mph. The RPMs went up very slightly--I believe it went from 2nd to 1st. I've done a lot of research and found that it might be the Grade Logic system. However, this was on a flat surface. It was cool outside though.

Do you think the slight downshift is due to Grade Logic, or is this a sign (early sign) of a malfunctioning transmission? The transmission appears to work fine otherwise (no slipping, no harsh shifting, etc.).

Hi Christopher,

Thank you for the donation.

It is difficult to say if it is grade logic or the trans shifted slightly harsher than normal.

A longer period of monitoring would be required to understand the situation. As you already knows, grade logic works according to the condition and data available to the PCM.

Some transmission don't fail even after a long period of harsh shfting and the only problem you would encounter is the harsh jerks occasionally when throttle pressure is applied to accelerate.

Forget about worrying when the transmission is going to fail. If it is going to fail, there is nothing that you can do to stop it. Whatever maintenance and fluid change should be done accordingly and the rest is beyond our control.
