Kashif get a multimeter, get. Second person, extend the wires of your multimeter till they get to the tcm set to continuity, run thru all the transsmision connectors that go to the tcm. This involves removing the socket from the tcm. Don't forget to dissconnect battery terminals.


If all all the connections checkout then 3 things might be involved

1. Possibly a faulty tcm
2. Possibly a faulty transmission
3. Witchcraft.

Get either Mastech Digital Multimeter, MS8261 Series (good enough/cheap) or Fluke 115 Compact True-RMS Digital Multimeter (professional level/costly)

In one sentence, since I didn't have the above, and I didn't know where to get them original locally, I had to sublet the repair

I have a good multimeter, but it is in the car, and the car is far from me at the moment. Something must happen this weekend anyways!

After all the attempts, the new tech has come up with a verdict: Seller should send another transmission! I really love the sound of this transmission. Still don't know why this should happen.

There is a twist as I have today discovered: Seller sourced from a primary seller, as he did not have it in stock. Primary seller claims his transmission was in good condition. story for the gods!!!

Very funny this seller might even have the transmission, but because it did not come from a Rav4, 'he does not have it'.

Tomorrow would be snake in the monkey shadow reloaded!

You are making progress.

Where is your car located?

Festac Lagos.

Another transmisson is being installed at the moment. With this my experience, I am inclined to train as an auto transmission rebuild expert. Can't understand why there is none in Lagos.

Really?

back to gloat?

Another transmission installed, and problem persists. This has been narrowed down to the TCM.

I really regret the death of the first replacement transmission. A very sweet box

Now, I need to get where this vehicle is!!

Any idea how much this ECU costs?

On now

Hello bro,
Have you performed the ECU swap? and if yes did it solve the problem?

Nope it did not. I asked the tech to stop when it became obvious he was grappling with the issue. My ECU was reprgramed and re-installed. The test drive went well. I need to flog the vehicle on extended highway before establishing my satisfaction.

Worthy of mention is that I noticed one or two functional restorations already.

Guess the ride is better now

or is isnt?

Inception:
Guess the ride is better now
or is isnt?

Its good now.

Kashif:


Its good now.

wow, congrats bro.

then most likely it was the brainbox? or poor electrical connections?

Kashif:


Its good now.

Can you tell us how it was resolved?

It was more of electrical connection. I believe the supposed corrosion at the connector was the culprit. The mechanic mistook the initial learning process for malfunction, and called for ECU replacement. The replacement ECU did not fare any better so mine was reinstalled.

The test drive went well, and that was it. My ECU reprogramming fixed my one touch up window control, and LTPMS malfunction. The vehicle was away for six weeks!

@kashif running a scan on that vehicle would have been the first thing to do this would have given you more insights as to why your transmission fluid got burn because that doesn't just happen.

As for rebuilding your transmission, YES IT CAN WORK. but under one condition. DO YOU HAVE O.E.M REPLACEMENT PARTS AVAILABLE? if you do then carry on.

Firstly, I will say that reading your post here enticed me to join Nairaland.
I was highly touched by the pains you passed through just to put your car in order. While in a different country I experienced gearbox problem in my car, having changed gearbox 2 times in a year I gave up and sold my car in a throw-away price just to save myself from the anger. After that my second, third and forth cars all went fine without any gearbox problem before I sold them.

I just bought 2007 Toyota Rav4 V6 with low mileage and recently I had one problem (Car won't start) so I was searching online and found out that MANY in USA had the same problems (From 2006 to 2010 Rav4 models) which is the fault of Toyota which has to do with the "Neutral Start Switch Assembly" the small trick to temporary solve the problem is "push the gear from neutral to parking then start" but maybe you are lucky your car neutral safety switch was changed in USA before you bought it.......refer to:

Another problem you may experience is the battery, the battery life in Rav4 (2006 to 2010) does not last long because it has many electrical burden on it even the power steering depends on the battery. In most cases it dies within 2 years (Experience from others).

>>>>>>>You are the first person that I am learning this gearbox problem from and it made me worried as I would like to keep this car after using it. From your experience it shows that the gearbox is not really the problem but the electrical. Well if you have more to share from that your experience I will be much glad to learn so If in any case (I don't pray for that) I encounter such a problem in future I will know how to tackle it because many mechanics may not have a clue....As I said you are the first person that I am learning this problem from but doesn't mean that you are the only person who had such problem, just that I never make time to search google about: 2007 Toyota Rav4 Transmission Problems.

MY ADVICE: Whenever you had such kind of problem in your car, Spend your time to search the problem in GOOGLE and you can learn from many who has experienced such a problem because the problem must have been in existence before you.

You should have Car Diagnostic tool to scan your car for error codes, don't always rush to mechanic because most of them in Naija work by guessing "It maybe this, it maybe that, change it" at the end the problem will not be solved and money wasted.

Planning to visit Naija soon, I just need to buy some of those tools (Multimeter, OBD2 scanner & so on) at least I could know the problem of my car before calling a mechanic to fix it. I hate when they work by guessing because the more they guess the problem of your car and tell you to change what is not even the problem causing unnecessary waste of money.

Nice delivery. I am aware of all the electrical load on this vehicle - it varies with the trim. I have recently disabled the DRL; not just because of the load, but because I dont like it. Certainly, somebody else has experienced that problem, and it points to one direction - TCM reset. After digging, I have found that replacement of this transmission, ECU, valve body, and some solenoids require that the TCM be reset! It is annoying if you ask me but, that's the way it is. I also do not like the TCM calibration. I have the tool now, but I do not want to risk reprogramming the ECU (yet).

The no crank issue you experienced is a quick fix, and should not take resources. The car is strong, and reliable. What vehicle did you have to change the transmission twice in a year?

@Kashif.
My brother! sorry for late response. I have not really checked here for long as I was hoping that I will get notification via my email whenever you reply. Ok, Very happy to read your response..........Like I said previously that I am new here so I need to figure out how it works, hope you can see my first post? or maybe I should repost it again (already done that).

You disabled the DRL? Does it make any difference to the battery load? I think it needs more than that. Unlike you, I like DRL but not fog light (Most DRL I have used, will automatically put on when I start the vehicle and will go off when car is off, Fog light I have to switch on/off manually which I do not like because I always forget to put it off). I will also like to install Car Dvr Rearview Mirror; pic attached here (I love it mostly for GPS, rotatable Camera, voice record and packing camera) Do you think this will cause more load to the battery? Is there any high capacity battery that you may suggest that will carry the whole loads comfortably and still last normal?

I guessed you have used your RAV4 for more than a year, have you noticed anything with the tires fading faster than normal? What is your opinion on that?

AS U SAID: The no crank issue you experienced is a quick fix, and should not take resources. HOW

Your question: What vehicle did you have to change the transmission twice in a year? It is "Proton WIRA 1.6 1996" I bought the vehicle in the year 2009 with low mileage, excellent body, clean interior and sound engine but I changed gearbox twice in a year until I gave up. If you search google the problem of its gearbox is general, unfortunately I didn't search internet before I became a victim.

How about that gearbox you were fixing then? I mean the one you bought some kits from US to work it by yourself? Did you finally fix it?

Thanks.
Desmied

I disabled the DRL basically because I don't like it. Second, it will put less load on the battery, and improve lamp longevity. The electronics you plan to install will increase your electrical load by a margins I cannot readily estimate.

I completed the rebuild, but it is untested. At the time of rebuild, I did not air- check the clutches because I did not have the means. Now I do, will have to do it again.
