Hi this isn’t going to be a high tech post like I have seen on here. But I need my car running so here it goes. I bought a Honda Accord V6 with 130 miles in 2012 . It’s perfect, no troubles. Runs great. I keep all maintenance done. Replaced anything new CV axels, brakes, tires, checking fluids.
Min October I went on a rescue mission to get my kids out of Panama City after the hurricane hit. The storm was an electrical storm- high winds but lots of electricity . I started having problem when I drove back. Went to Honda and I need a new transmission. Thus city tried to screw men before on a Toyota transmission and it was literally 3 dimes stuck in the gear shift.
I asked anyone to show me how my transmission went out but I could still drive it 50 miles per hour. It was sluggish in 1st gear.
I ebed up going back to PC got the same transmission in a working car put in my car and had the same problem. I don’t understand all the sensor issues. Have taken it to auto zone and have codes. P1750, Po705 and 34-2, Po700. These were the sane codes I had before I paid 2k to replace the transmission. The person I had relocated out of state who worked on the car so nothing there. 15 people have looked at it. All missed the little piece on the right side of the transmission that has the blue and green wires which were reversed. After I swapped those the car ran like a new car. For about a week. Now those codes are back and the engine light is now on. It went into 1st hard then the check engine light came on. Can anyone assist me. I have spent days watching YouTube videos but I can’t seem to find the parts that they say are the correct name. Yes I am a mess, female . The most I have ever done in my cats are tuneups but I have a CDL A and have drove easy coast for years. Never had a car problem like this and need the car to work... please advise am I wasting my time ??

You probably just need to clean the screens on the shift solenoid sensors. Some of the sensors for those solenoids may need to be replaced as well, there are a few videos on youtube and various forum posts across many of the Honda models in this year range on this very issue.

How often are you changing the transmission fluid? If you are using DW-1 I wouldn't go over 20k between drain/refills. Ideally, and everyone has their own opinion on this, switching to a high quality synthetic fluid for the tranny is a good idea. I'm using Amsoil Signature series in my 02 Accord and 07 Odyssey and shift quality has definitely improved as a result.

shipo

Bad idea to switch to anything other than DW-1. Why? Because while any given ATF may have a superior base oil, it is an odds on bet universal ATFs do NOT have the correct Coefficient of Friction (CoF); the thing is, if the CoF properties cause the ATF to be too slippery, the clutches will slip too long when engaging and cause accelerated wear, the reverse is also true if the ATF isn't slippery enough, the clutches will grab too quickly and subject the transmission and drivetrain to excess shock. On your Accord and Odyssey, you would be best served to get that Amsoil stuff out of the transmissions.

There are two variations of the Amsoil signature series tranny fluid. The one I linked in my reply above is recommended as replacement for Z-1 (what her tranny shipped with) and another that will work in place of DW-1. I'm posting from my phone so I can't find the reference right now but the CoF of of the 1st type of Amsoil is a closer match to Z-1 than DW-1 is. Even more the CoF of DW-1 breaks down and is out of spec within the first 5000 miles of driving. The Amsoil maintains it's CoF up to 25k from the info I found. It was either in the odyclub forums or bob is the oil guy...I'll find it and post when I get home.

Gosh, you guys are sp smart! Thank you so much. Let me back track. Answer to changing oil. The tranny was changed with a working used model 130 miles and put into my 138k mile car. I was told to change the oil about 6 weeks after the install. The oil was bought at autozone, I dont remember the brand. I am hearing dont change the oil and change the oil. Change the filer but hear it doesnt have a filter. So I purchased oil at AZ again and it is a castrol brand transmax multi vehicle import oil. The plan was to change the oil. right yes or no?

As for changing the sensor or cleaning the screens. I just called AZ and got a part number to see what it looks like..haha, going to youtube to find a video. There isnt a way to check there parts to see what works and doesn't? I do not understand why it is so hard, even the names of the parts are different for different years. Very confusing. Any more feedback would be appreciated. At least I hope this puts a smile on your face today. I never understood how much an expensive piece of equipment could go bad "just like that" Thamks again..going to youtube Maybe when I get off my crutches I will go into the car business Xxxx

See here we go, I called Auto zone, asked for the the sensor and was given a part JA4308, that part is the safety neutral switch. Is this the same thing? Because I believe this is the same part that was taken off and cleaned before. The blue and green wire was reversed and spliced together. That was respliced and sealed. the car ran great for about 200 miles.

Me thinks you've been drinking too much Scamzoil Kool-Aid; the fact is, multi-vehicle ATFs almost never have the correct CoF for any of the transmissions they are "recommended" for. Having something "recommended" is not anywhere near the same as "is correct for", yes, it might be close, but you have no way of actually knowing that.

Long story short, the ATF in your vehicles is incorrect; while none of know how "incorrect" it is, sooner or later, your transmissions will fail because of that ATF.

Dkali

Thanks for the reply. Actually I dont drink, maybe I should at this point. All I have done is followed directions or took it to a place that should have known. 2000.00 isnt a small amount of money to fix a car and still have problems. I took it to a transmission shop last week to have the oil changed like I was told and again got you need a new transmission. It takes a lot of skill to be a transmission technician. Do you think it would be worth me taking it back to the shop and asking them to change the oil again?
I am not in a position to get a new car, I really need this fixed. Thanks for the reply.

shipo

The reality is the 4-Speed automatic transmission in your car has never had the reputation of being filled with anything more robust than parts made out of glass; said another way, the transmission is not known for its longevity.

If you plan on keeping the car for a while, I would shop around for someone intimate with these transmissions and is A) aware of the design short comings, and B) uses one of the very high quality aftermarket remanufacture kits; these kits go a long way toward making the 4-Speed unit pretty darned reliable. If you are only going to be keeping the car for a short period, look for a used transmission from a bone yard and throw it in; start here: Car-Part.com--Used Auto Parts Market

I appreciate all your comments, the oil problem can be fixed. I do not understand one thing. The same exact problem I am having with this second transmission is the same I had in the begining with the original transmission. Shifting from 1st to second up and down. Its is an intermitteant problem.

Is there a silinois, sensor, part that is exclusive internal or external to the transmission that would make this happen. I went to the shop and asked this question. If you change out my transmission like I have already done and I have the same problem which I already have what would you do. They said start checking sensors.

Can anyone answer that one question? You guys are smart, please help me.

shipo

Hmmm, my 2001 Accord V6 never had such issues, even when I left the ATF in way too long.

When you changed your transmission on the prior occasion, what did you replace it with?

Dkali

Hey shipo,

I contacted the person who actually changed out the transmission. My son actually purchased the correct oil that went into the transmission, the new transmission. Or the transmission that came out of a working honda that I drove. I was told to change the oil again in 6 weeks..the AZ oil is an error and can be taken back.

Again, the issue is it still has the same problem. I just found a thread that addresses something called a 2nd clutch pressure switch. The issue seems to be between the 1st and second gear. No transmission errors at this time.

shipo

It shouldn't cost you much to swap out the pressure switch; it seems that would be the most prudent first step. If that fails, well...

Keep us posted.

Dkali

Thank you, trying to find the part now. It seems to fit. I appreciate all your help/listening. I hate to loose the car, its a beauty. Hopefully Saturday. I will let you all know.

P1750 - 'Mechanical Problem in Hydraulic system'
P0705 no such code, there is a P1705 'Transmission Range Switch(short to ground)' this is attached to the outside of the transmission
34-2, no idea what this is, sounds more like an ABS code but the '-2' is not used.
P0700 - generic 'trans problem' code set by generic code readers, it adds nothing to diagnostics other than telling you what you already know.

If P1750 code is indicated with other codes, ignore P1750 til the other codes are solved.

If P1705 code is set this can cause erratic or no shifting as the PCM will not know what position the gear selector is in. If the harness is not properly connected, the pins are loose/corroded/damaged, or the switch was installed not properly lined up, this could cause a malfunction.
If the codes have persisted there may be a problem with the wire harness for the gear position switch that is causing it to ground out. The harness does hang under the transmission and can be damaged by debris, or the switch itself can be damaged.
2nd and 3rd gear pressure switches can go bad and cause harsh shifts, usually they leak when they go bad. They also do not set off the CEL or D4 warning lamps. Only way to retrieve the code is through an OBDII scanner.
One other note, engine tune and functionality will greatly affect how the transmission operates. The later 98-02 cars are a bit 'smarter' in self diagnostics, but if there are any engine issues at all fix those problems first before continuing diagnostics on the transmission.

Mike, Thank you for your response. There are no engine errors. I only have the 700. The only dash lights are the TCM and the ABS. There is nothing else at this time. I took the car to a transmission specialist again yesterday. He is the one who said the only thing he sees is going from 1st to second. This was the same problem I have before the transmission was changed., If I baby the car it drives fine and I don't have the hard shift going into second. It doesn't happen all the time. I have heard the term pressure mentioned before combined with 1/2 gear.

I am not at a loss, as I said before. If I put another tranny in and have the same problem I am still back to square one. That is all anyone wants to do. About 7 years ago I had the same problem with a toyota. Was told new transmission. I opened up the gear box and found 2 dimes..yup 2 10 cent pieces lodged in between the gear box. One pair of needle nose pliers fixed it. I cant even find a shop that will offer to do anything besides offer to change the transmission. Obviously I cant fix this car which is a huge hard ship. Thanks for everything...I fold

One last thought, I went threw a storm, tree branches everyplace. I thought I was dragging something under the car. People stopped and helped me look under the car. Honda and my insurance company both said they saw nothing.
