Transmission replacement?

Hi val_mar33,

It does sounds like the transmission could need replacement here are the instructions in the diagrams below. Check out the diagrams (Below). Please let us know what happens.

I recently replaced my transmission which is used on my accord 1999 with approx 120,000 km and my 1st and 2nd gear shifts are fine with no trouble but, my 3rd and 4th is delayed where my engine over revs and then shifts after 10 seconds of changing gears. Is it possible that there is an issue with the solenoid and which is it?

Was that the same problem with the old transmission? Also have you checked for trouble codes in the transmission yet? This sounds like a revolution sensor problem

No, when the previous transmission comes to a stop, the transmission jerks very hard and goes to neutral and it had was tripping whan it had enough ATF and this is why I replaced it with another transmission.

Alright have you checked for codes in the computer yet?

I will when I get home, I was reading on other sites the shaft speeds sensor can cause this problem?

These are the same sensor. Here is a video of the job being done.

Yep that did the trick once I replaced the sensor the transmission started shifting again.

Thanks for your help this site rocks!

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

Cheers

I'll try to be brief. In 2008, i put in a low-milage transmission with a 90 day warrenty becasue i could not afford a new one. A few days after i got the car back, the key was stuck in the ignition and there was this pulling or tugging underneath the car everytime i reversed. It also was loud. Change the engines mounts, which were broken, and had the transmission examined for the tugging. Still nothing. It took the mechanic a year to figure out that i need a new wire installed that connects the gear to the ignition. Do you think that installing this wire will allow the key to release easlily and stop the tugging or pulling when i reverse? Is the ignition and gear somehow connected to the transmission? Do you think the wiring is off?

It could be a wiring problem. Today's transmissions have several electrical devices that make them shift, determine speed... And yes, wiring from the ignition sends power to it. However, I can't say for sure it will allow the key to come out easier.

Hi, all

I have a big problem after rebuit trans.

Trans Tech rebuilt my trans one month ago.

They changed trans cluth kit and TC.

good for two weeks (800 miles).

Then D4 light blinking and check engine on.
The car can not shift to 4th gear.
checked trans oil level - good.

Back to shop. after scan.
They changed solenoid B and pick up solenoid.

good for 50 miles. and D4 light blinking again.

I am not sure what happened in my car.

Thanks for your suggestion.

Hi dahua.huang,

When the D4 light starts blinking, an error has occured and been detected by the PCM.

Get the Diagnostic Trouble Code and we will see what can be done.

Hello,

Basically my question is regarding the cost to replace my transmission with a new (rebuilt) transmission from Honda.

I have a hum that I thought was the wheel bearings, so I had them replaced. The hum persists, and I also have transmission fluid leaking out from where the CV axle enters the trans. The leak is progressively getting worse. Also, I checked for play on the axles and they both move quite a bit. My understanding is that the carrier bearing is going causing the axle to shimmy allowing fluid to seep from the seal. The car has a lot of miles but its extremely clean and worth the money. Thanks in advance. Brad

Hi there,

The prices i come up with are Transmission approx $2.800 and around 12 Hrs labour. I would first get a test and report on your transmission first, and it it is deemed to beyond reasonable repair, go get a few quotes on this job as well, my price is from Mitchell 1 data base and this may vary depending on your location.

mark (mhpautos)

the splines of the differential where the axles goes in have a lot of play. is it normal if not what should I replace the transmission its a BOYA . I have a 96 Honda accord 2.2 liters

What's a BOYA? Some play is normal in the inner cv joint. The housing is held in the transmission with an internal spring. If you can slide that joint in and out an inch or two very easily, that's when you have a problem. It should slide in smoothly under hard hand pressure, then spring back out by itself.

I could not understand what did you say .BOYA is what the transmission is called . when I put my finger inside the differential where the axle goes in the splines of the differential moves a lot.

Was the half-shaft causing a problem? Why did you remove it? I suspect you're feeling normal movement in the small gears that are part of the differential. Those are what are splined to engage the half-shaft.

ok
few days ago I saw transmission fluid on the drive way it came from the passenger side drive shaft . I took off the passenger shaft and I saw wear marks on the end of the drive shaft where it goes inside the differential. so somebody told me its the bearing because the spline of the differential has a lot of play

Dandy. Before you waste any money on something that might not be needed, take the shaft to a Honda mechanic and have them inspect it. Out of 100 cars that leak transmission fluid from a half shaft, 99 are going to have nothing more than a worn seal. Those are about five bucks. The metal parts, including everything with splines, are hardened steel. I've never seen those parts fail, and if there was excessive wear, you would have had some noticeable vibration before this. I'm hoping you're finding a problem where there rally isn't one.

but the differential spline are loose I can hear them when I put my finger inside the splines is that normal? and there is friction marks on the end of the drive shaft

I'd feel better if you had a mechanic look at the parts. There very well could be something wrong there, but until I see it myself, I'm betting you just have a bad seal. If you reach inside the differential to that splined gear, that will move around. There's just the teeth of two mating gears holding it in place while the half shaft is out. You'll see two machined and polished surfaces on the inner cv joint next to its splines. The smaller diameter one rides on a bushing and there will still be some play there between the cv joint and that bushing. The larger diameter surface is where the lip seal rides. That seal is flexible enough to move around and follow the cv joint as it wobbles. If there's leakage there, there's one of two causes. The seal has become dry-rotted and / or hardened from age and heat, and it has cracked, or that bushing has been chewed up. I've never actually run into a chewed-up bushing. There would likely be no damage to the cv joint because that surface is hardened, but the bushing is made of very soft metal and you would feel the roughness, and you'd find a pile of gold metal flakes when you wipe your finger inside. Many bushings have oiling grooves in them. Don't let those fool you into thinking that's damage or wear.

With excessive wobble from a worn bushing, the cv joint can move far enough away from the lip seal to allow it to leak, but you would most likely also feel a vibration at certain speeds. Rotating parts that wobble have a "resonant frequency" they like to vibrate at, just like the pendulum on a grandfather's clock. At anything other than that rotational speed the shaft or joint is less likely to vibrate. Hit that magic speed though and you'll feel it. That much wobble would cause quite a bit of fluid leakage while you were driving, and usually less leakage standing still.

If you can see into the center of the seal. try to see if here's any cracks in the rubber. If you see any, the rubber is hardened and brittle. Pop a new one in and the leak should stop..

I will show you pictures of the smaller surface diameter of the inner end of the cv axle how it looks like.
however i took of the transmission from the car and i disassembled it .i could take off one of the baring of the differential by hand and put it back what this tell you please ?

Your pictures didn't load. Other people are having the same problem. I don't know what the answer is, but I think they have to be in .jpeg form. I used to be able to use Microsoft Word to draw pictures, then copy them to Microsoft Paint and save them as a .jpeg file in the drop down menu. Maybe that still will work.

ok i upload one picture of the axle end . the problem was the size of the picture the website does not accept big size pictures so i had to cut it using paint

Wow. You definitely do have an issue there. Look for a bushing outside of that splined gear that's chewed up. The gear can be loose. It meshes with two other similar gears. Along with the one on the other side, they all rotate inside the differential assembly as a unit. They won't cause a vibration, but that bushing will let the inner cv joint move away from the axle seal too much and cause the leak you found. You might be able to replace that bushing by using a special tool to pull it out once the seal is removed. The new bushing is tapped in but be careful to not twist it or push it in crooked. That can deform it and cause it to rub on the cv joint and fail again. Use a new seal too.

i disassembled the transmission i found metal shaving where the outer bearing race lives ( transmission housing) . i could remove one of the two bearing by hand i know these bearing should be pressed in . what is the issue here i could not figure out .

Not sure what issue you're referring to. That bushing is pressed in but to my knowledge, there's no bearing that's pressed in. If you remove the small bolt in the differential that lets the large round pin slide out, that will allow the two axle gears to fall out or be lifted out. That large pin also has two similar gears on it. Those will fall out too. None of those four gears ride on bearings. The outer two do turn with the cv joints, but in relation to the housing they sit in, they only turn a little, and very slowly, when the two front wheels are going at different speeds, (turning a corner).

I think the small bolt that you talking about its a small pin how can I take it out?
and I will try to load another picture for those bearing that I talked about

Not sure what Honda uses in their differentials. U.S. domestic cars have used a 5/16" head bolt since almost forever. The threads are right under the head of the bolt, then the pin extends about another inch. Sometimes when that large center pin gets hammered out, the pin can shear off. You can often get them out by drilling a small hole next to it so you can reach in with a pick to pry it out. That happens most commonly with manual transmissions because you're on and off the power so often when shifting gears.

this is the picture of the bearing that i talked about

I don't see anything obvious there, but it's hard to tell from a picture.

i know they press in those bearing on the differential house, but mine i can put it in and take it off by hand its not tight on the differential anymore . what could causes that?

after putting new transmission in a couple days ago the transmission and motor are shaking when the right axle pulls should i replace the axle? or something else

make sure the motor mounts are good and tight

roy

yeah motor mounts are good and tight but it still seems to overpower that one guy said on another similar problem that wear on the joint housing can be unnoticed untill u take them out and put them in a different car i did a similar thing by changing the transmission when the transmission moves a slight bit couldnt it start changing the ware point and make is shake from the other worn spots?

yes it could. did you use a new or used trans??

roy

used and the transmission works great and as a matter of fact i had problems with the axle staying in the same one that is shaking and i got it in with hammer and block of wood. seems to e staying in now but leaking a little im gonna change the seal when i put a new axle on in a few days do you think that will take care of it?

i would suggest doing that as a start
