Femtopford: It's absolute to determine defective components in the transmission without opening it, but not a rewire. A competent automobile technologist should be able to say positively area to work in the transmission. (1) FLUID PRESSURE/TORQUE(pump, converter and solenoids assy) . (2)TAKE OFF AND SPEED/TORQUE SECTION(solenoids assy and valves body). (3)THE DRIVERS/INPUT SPEEED(pressure pots/plates and turbine sensor ). (4)THE DRIVEN/OUTPUT SPEED(driven pots, plates, fibre and output sensor). All these on basic technological procedures bellow. Condition and performance surrounding the transmission along with comprehensive diagnosis How would you know a clutch/brake/band is to be replaced without seeing it? If a holding member is slipping, do you think replacing it would solve the problem? No! You need to address the root cause. From diagnosis, you can determine slippage, but you cannot call for a clutch replacement without seeing it. Have you not seen where ECU reflash cured slips and shift feel? Yes, you can say a VB is bad, TC is bad, pump, etc, without dropping gear, but not clutches. I am telling you from training and experience. |

Femtopford: Am not referring to wear and tear but unnecessary anomalies caused by external influence. There's not a single physical nature that doesn't wear out with time.
Human being wear out, even houses and buildings that are classified to be greatly appreciated still wear and depreciate, you get to repair one or two things on the building as time passes by (renovation).
Needs not a long dispute, to really comprehend my analysis, get one of your Ford vehicles from 2008 upward and services with either seahorse or Holt transmission fluid irrespective of their dextron level. the transmission won't perform up 30 minutes before it breaks down compare to 5-10years excellent performance with loyal service specifications.
Why so. Different fluids are produced with different organic compounds. When temperature increases as engine works, increase in temperature breaks down the fluid's organic chain faster than necessary there by loses it's viscosity power and the specified viscosity index meant for the transmission is disobeyed.
So when the solenoids in the Transmission activate by the command of the TCM(brain box), to allow flow of fluid, there will be stuck or late opening of valves due to unspecified viscosity leading to ache engagement or late speed selection.
More over, continuation of using the transmission in such condition will cause the fluid to fry up the the solenoids and burn the electromagnetic inductors of the solenoids, so there won't be selection anymore and slippery of frictional clutches, the transmission will finally condemn. Oxidised oil as you put it will not affect solenoids. Only dirts and contamination do. Yes, PWM solenoids are more susceptible than on/off ones. Oxidation will affect holding members and maybe, seals. Oxidised oil will not cause overheating - it is the other way round. If you take away the cause of overheating, oxidation stops. I agree with you that regular service will prolong the life of a transmission, but will not give it eternal life. Some transmissions are known to fail under 50,000 miles from factory. In modifying those, oil paths/pressures are increased, decreased or rerouted as the case may be. I made my input because you said auto transmissions will not give any problems if serviced regularly. Shalom. |

Not sure how this works in Nigeria. I went to Spar on Friday, not knowing what was happening. I sensed something was abnormal when I couldnt find a parking space before 11am. Eventually got into the compound and on asking questions, realised it was black friday. Needed a small Jbl bt speaker that I had bought before for 14,150. On black friday, it was listed at 15,050! I asked the sales rep why it should be higher since commodities prices are coming down (I never considered the BF). He then told me there was a 10% discount on the speaker.  At the end, I paid 13,545! Why did they have to increase the price before the discount? You judge! Was not tempted by whatever it was they were painting black! |

olaremint: Dear Fem I just bought a tokunbo Ford Focus 2004 model. It has transmission issues. When accelerating the car jerks while trying to select from gear 2 and burst to gear 4. The gear indicator shows on the dashboard and and then it starts to work fine. A mechanic took it for scan and said the readings came out with gear selector switch. A rewire there also checked it and sais the fibre in the gear has to be replaced. This is a pix of the car. How can a 'rewire' determine that a transmission's 'fibre' needs to be replaced without opening the transmission? |

canagbado: Please, Kashif & co, I am in Lekki Lagos and drive a 2008 Camry with 13-pin gear box. The story is long but the car is parked in my house & I need candid advice from Kashif as to what next. I am planning on spending some cash to fix it month end. Briefly, mine got burnt due to leaking oil from the shaft. Their was an attempted repair but to no avail. Was moving for a while without the socket being plugged but was as good as the car had no gear. Now, I want to remedy it and I need assistance at this moment.
I will need to see Kashif life and we can discuss. Do you know details of repairs carried out? How does it drive currently with the wires hooked up? What does the atf look like now? With the wires unhooked, do you loose mobility or just the normal powerless 3rd gear drive? |

nurey: Apart from ground clearance, I think they are both capable of achieving same feat.
The fortuner and previa are due to stringent rules in Asian countries concerning car size and engine. The sienna and 4runner have more tax associated, so to counter the effect it would have on sales, they decide to down scale them to something different Interesting! |

tadtoad: What do you recommend for my situation below?
Car: 2007 Camry, Gearbox type: Automatic "13 pin"
I recently had the valve body and "fiber" (do they mean solenoid?) replaced since my gearbox was shifting hard and not going passed 1st gear. After fixing, the gearbox guy adviced that when I drive I need to take it slow while the brain box can get used to the changed valve body and "fiber". It all seemed fine for 2 weeks then...
Yesterday, after driving above my usual 60km/hr on the express, my check engine light comes in and after using my scanner, the error code P0741 shows up. I've Googled the error code and it's "P0741 TOYOTA - Torque Converter Clutch Solenoid Performance".
From forums and YouTube videos they say the torque converter should be changed. Is this correct in your opinion? What do you recommend?
Thanks Wonder what could have just killed your TC. Look for a tech with capable scanner and test the TCC solenoid (SLU) with ignition on, and engine off. If the solenoid is good, you will hear it click on and off. You must put your ear close to the box to hear the clicks. If it clicks, the solenoid is good. If it doesn't, solenoid is bad or computer instruction not reaching it. If it clicks, start engine and while in drive and foot firmly on brake, activate SLU and see if the engine dies. If it doesn't, you have a stuck TCC relay valve in your VB. If engine dies, you have a slipping TCC or wrong internal part. When lockup is commanded, the computer is looking for zero difference between the engine RPM and the transmission input speed. Once it sees any drop, TCC code is set. However, if a wrong drum or differential is installed, it will distort the computer's input signal, which it would see as a slip. Hope this helps. |

nurey: I know the fortuner is just an hilux in suv form, but the car isn't really bad
Quick on the line even with the 2.7L engine, the TRD sportivo is well padded, has third row seat though a bit cramped up with leather and reverse camera, the 2008 face-lift isn't bad at all.
If you are a fan of the Toyota 4runner/hilux surf, you did like the fortuner as it looks like and outdated vehicle but performs brilliantly well. Also has a tremendous ground clearance other vehicles would wish for in Nigeria With tremendous ground clearance comes tremendous rollover tendency. Wonder why Toyota makes Fortuner and Previa. I don't think Fortuner is more off road capable than 4runner. |

A healthy vehicle at idle could roll backwards in drive on a slope, depending on these factors:
Size of engine
Gradient of slope
In-gear ratio - the steeper, the lower the possibility
Weight of vehicle
Torque converter stall speed - there are three speeds. |

What a thread!
This is Cartalk, known for maturity and mutual respect. It's is supposed for knwledgeable minds and learners alike. We don't need to hurl disparaging remarks at each other. Somebody does not know what you know simply because he has not been exposed to it. A perfect mind is all of us put together. I love civility but know I have been found wanting too! Too much space and time have been taken here on personal attacks, instead of education.
Peace everyone!
On to the matter.....
Even if the air filter hose in a MAP system is burst completely open, and funnel attached, the MAP reading will not change, and the engine should not run lean. However, if there is a post MAP leak, there will be engine performance issues.
Even in MAF design, a post MAF leak will have little effect on the MAF reading (depending on the size of the leakage) but will cause performance issues due to the unmeasured air.
The difference in STFT and LTFT is in their names. Short term tells you what is happening now while long term tells you what has been happening. Assuming the open hose has an effect on the FT in Gazzuzz experiment, it would show in STFT, not LTFT. If a lean or performance code is not set in 100km, I don't see it setting. To eliminate all doubt, run the car in check mode.
On the flip, for that engine to have a LTFT of 16% means there is an underlying problem. There is too much air going in, or there is fuel supply problem. I personally will be concerned if my LTFT is more than 3%.
Shalom. |

Emmanhack: Update : knock sensor fixed still wont shift to 3rd gear, i checked the gear oil (just poured 5 days ago Honda DW1) its has turned black and smelly Are you sure its the 3rd gear that is inhibited or the second? You are most likely having a command issue, which shouldn't fry your transmission. What is the computer commanding? What I know is very delayed 1-2 shift which would usually hit the rev limiter, and then goes in harshly. A major cause is worn or tight valves in the engine bank(1) close to the firewall. It causes the MAF to read wrongly, which would confuse the ECU. It is common with V6 Honda/Acuras. I think these valves should be adjusted at 100k. Other causes I have seen are low engine oil and disconnected/malfunctioning engine coolant temp sensor. Check all these. At this point, PIDs are more desirable than codes. MODIFIED: It will be nice to know what your long term fuel trim is saying. A negative value points more to the valve problem. |

obekediamondfuto: go for comprehensive scan. how do u know it jumps from 2-4, is there any jerk or slip in change? at what rpm will it likely make the change from 2-4?
doesn't seem like an extremely big deal. probably some solenoids needs servicing. bad pcm can also cause this but I highly doubt.
