Slow response on acceleration

Hi,

I haven't heard from you for some time. It looks like you have another tough one. I have a question. How dirty was the transmission fluid that you removed? When the pan was off, was there a lot of debris?

There is a chance you will be replacing the valve body if the fluid was bad enough. However, I attached the diagnostics below for all three codes. Take a look through them and let me know if you have questions.

Also, the P2808 code is last below. I included the description with that one because I personally would start with those tests. I highlighted where the diagnostics start for that code. The two other codes just include the diagnostics.

Take care,

Joe

See pics below.

Good morning, Sir,

How will I know that the fluid is dirty?
I just know if the fluid is overheated or if it contains metal particles. You mentioned replacing the valve body if the fluid is bad enough, can't the valve body be serviced?
The test to be carried out, is it only techstream that can be used or another scanner can be used?

Hi,

I'm not sure what you mean by "how will you know if the fluid is dirty". If it's darker in color, smells burnt, and so on. As far as replacing the valve body, that is a possibility. Chances are you will be able to locate the issue based on the diagnostics above.

And yes, you can use any scan tool that can communicate with the control module and perform the tests.

Let me know.

Joe

Okay sir, thank you very much.
I will get back to you sir.

Hi,

I was wondering if you have made any progress. I haven't heard from you for a few days.

Let me know.

Joe

Thank you very much sir for your concern.
Most times I find it difficult to follow what was written or the procedure listed because I don't have the necessary equipment. Some of them are expensive and some I cannot easily found them in Nigeria which makes diagnostic some difficult. Most times I try to improvise which might not be favorable.
The techstream is it only for Toyota and Lexus?

Hi,

No problem whatsoever. I understand.

As far as the techstream, that is for Toyota/Lexus/Scion vehicles. You must have an active professional level subscription to use Techstream software, so it isn't the most convenient or inexpensive means to work on them.

Let me know if I can help.

Take care,

Joe

Thank you very much sir,
Hmm, for a start which one do you think is better?
I was considering launch CRP 233 but it seems that it doesn't not perform active test and freeze frame data.
I want to get transmission oil gauge.
I am also thinking of focusing on Toyota and Lexus alone basically the electrical systems, but I don't know if it is a good idea.
What do you think sir?
What are the major tools needed for a start sir for proper diagnosis?

Hi,

If you plan to work on them often, I recommend getting one that provides live data (active data). That will help you in many ways. For example, it can provide fuel trims, oxygen sensor info, fuel pressures, and so on. It is really helpful.

As far as the gauges, just get ones that will read 300 PSI +. Pressure can get high.

Let me know what I can do to help.

Take care,

Joe

Thank you, sir,
For the gauge, where to get it is the problem.
Good morning.

I was thinking of using A/C manifold gauge and finding an adapter that can fit into the transmission, but I was told that it won't work because it was designed for air not liquid. I thought the gauges are the same, only the adaptor (the end part) was different.

Hi,

That is correct. The A/C gauges are for a gas and not liquid. I attached a pic below showing what you need. Isn't there anything online you can purchase? I'm sorry, I have no idea what you are able to get there. This is not an uncommon tool here. The pic I attached is from Amazon, but I have no idea if they will ship to you.

Where are you located again? I would be willing to get one and send it to you, but I have no idea what the cost would be to ship.

Let me know.

Joe

Thank you very much for your concern.
I am in Nigeria.

If you want, let me know. I will try to find out what the cost would be for shipping. Interestingly, it sounds like you don't have the common tools for diagnostics. I am very impressed that you are able to come up with alternative ways for diagnostics. But it has to take a lot longer for you.

Let me know what I can do to help. If you have any idea how something would ship there from the United States, let me know.

Joe

Okay sir.

Thank you very much.

Sir, what is the net weight sir?

I want to try this out:: https://new.shopandship.com/

Hi,

That looks interesting. Hopefully, it will work for you. As far as net weight, that is how much a product weighs prior to shipping. (I think that is what you asked).

If that wasn't your question, let me know.

Joe

Good evening, sir,
I asked for the weight because of the shipping.

Hi,

I don't have access to the product's weight. It can't be much. I traditional scan tool usually isn't more than 1 pound. That can be affected by packing.

Joe

Okay, sir.

Good morning, sir,
The weight of the gauge is 3 lb.
For the shipping from United States, it is $5.00/lb.
Shipping to where I can collect it is $10.00.

That is much less than I would have expected. Are you going to order it?

Joe

Good morning, sir,
Since I will spend $25.00 on the shipping and the gauge is $20.00 which makes the total $45.00. I will order it.

Excellent. I'm glad to know you will have it. You need specialized tools, or it makes work nearly impossible.

Let me know if I can help in any way.

Take care,

Joe

Good morning, sir,
Thank you for your support so far.

Good afternoon, sir, l sincerely apologize for posting these here, I am not supposed. I would love to diagnose components or systems the way they are supposed. I was studying a book and saw the question below, I thought about it several times, but I could not figure it out. I don't know if you could be of help.

Hi,

Which question are you referring to?

Joe

Good morning, sir,
It has been a while.
Sir, I want to educate some person on automobile, is it a good idea to speak on immobilizer on public?
I am asking here because 2CarPros has been of good help.

Hi,

Welcome back. If you are concerned that you provide information to make theft possible, I wouldn't suggest it. I always tell people we can't provide that type of information. However, if you are trying to explain why a person is having trouble, within reason, which should be fine.

Great to hear from you. Take care,

Joe

Okay, sir.
Thank you very much.

You are very welcome. It was great to hear from you again.

I hope all is well.

Take care and stay in touch.

Joe

All is well, trying to figure out something.

Good evening, sir,
Hope you are fine sir.
Could there be a way to test vehicle electrical system (module) before replacement?
I am trying to create a platform or garage where electrical components (sensor, module, solenoid) can be tested for functionality before replacement and want is expected signal is expected of them.
What is the basic equipment to use?
Is there any way to test ECU without or within vehicle with basic tools?
How would someone know the exact pins to check for?

Hi,

I hope all is well. I have to ask a favor. I need you to start a new thread with this new question. We try to keep the threads specific to one topic, so it is more helpful to others. I hope you understand.

Here is the link to start a new thread. Simply copy and paste your question into the new post.

Again, I hope you understand.

Take care,

Joe

Good evening,

Thank you very much for your concern.
Sometimes the signals that I do see on some of the diagrams that have been sent can be viewed with an oscilloscope or lab scope. Please there any small one that you can recommend, I am trying if I could get the basic tools to make diagnostic easier or to follow what is on the manual or images been sent.

Hello,

As far as an oscilloscope, they range in price from inexpensive to very expensive. I attached a pic below of one that should do what you need and it isn't too expensive.

Take a look at it and let me know if that would work for you.

Joe

See pic below

Thank you very much,
I will try and get it, it seems that it can make diagnostic easier. It seems that it is from AliExpress, please could I get the link, because I saw some that looks alike but the price are very different.

Hi,

You are correct. It's aliexpress. I attached the link below where I found it. Let me know if this helps.

Take care,

Joe
