Hi Car doctor i have a bit of a problem with my toyota highlander 2002 model dont know if you can help or anybody, the thing is that each time i drive the car i notice a jerk from the transmission and the engine sound begins to rise without the car actually moving accordingly and from that point it begins to misbehave that when i come to a stop the transmission doesnt engage to reverse again till probably the engine cools down. this has been giving me series of headaches as am very confused after i had changed the brain box and gear box. pls i seriously need help on this one. |

Re: Automatic Gearbox Problems by Nobody: 8:26am On Jul 24, 2015 |
Kashif:My Honest and sincere opinion based on my personal experience, most of the fairly used cars (especially the Nigerian used ones) advertised on this forum are very neat cars yet offered so cheap, I discovered most of them are automatics and have serious transmission issues that explains why they are offered cheap cos the repair cost apart from being too expensive are not guaranteed to last. I have nothing against autos, but our mechs still havent figured them out yet, all they do is to dismantle the gear box and persuade you to buy another unit with a 50 percent chance of success. 1 Like |

kaeforum: I agree with this completely, but disagree on manual being the best for everyone in Nigeria. I know many people who will pay anything not to drive a manual. For sure, auto transmission repair is a nightmare in Nigeria. I have experienced it but, do I wish to drive a stick in Lagos? No way! I spent all the money to be able to still drive the auto. My terrible experience, and the helplessness we all face have prompted me to start looking for solutions. There is hope in the horizon... 2 Likes |

Sir, I use an Automatic 2000 toyota camry. The transmission oil level is low and I don't know the if the oil in the gearbox is dexron II or III. Due to this, I want to replace my transmission oil. Will it be safe to use Sea Horse dexron IIID atf? Or can I just top it with the oil above. Please, help me ooooo |

Kashif: Hey Kashif, car doctor, usAutobuy et al thanks for all your insight on this thread I hope you advise me on my own issues. I have read all previous conversations but I think my problem is slightly different. My car is a 2005 camry I4, VVTi engine U250 transmission. I recently replaced the shaft due to the unbearable shaking. I drove the car back to my house which is about 34km from the workshop without issues. Then in my neighborhood I stopped to buy some stuff and started my car shifted to drive I noticed it stalled to engage. Then I drove awhile it revved and then engaged gear 2, to engage gear 3 it revved the engine again to engage. I carefully drove it home. The next morning I tried to drive the car it repeated the same issues of the previous day, then I noticed it doesn’t downshift when I slowed down I have to engage park and then come back to drive. I also noticed engaging reverse there is a jerk which wasn’t the case previously. The next point when I engage drive no traction at all. The gear only moves when I engage reverse. I have taken it to a gear specialist who serviced the valve body but the issue is still there. We changed the oil I always use the recommended Toyota T4. The issue is still present. Please can I get advice on the next step to take. I stay in ABUJA. |

Re: Automatic Gearbox Problems by cardoctor(m): 9:32pm On Aug 19, 2015 |
obi2ice: Too bad. It seem that your mechanics were quick to remove the drive shafts without alowing the gearbox to cool down properly. Once the drive shafts are removed, cool air passes through the gearbox when the gearbox is still hot. The valve body and other internal components are supercooled causing the solenoids and valves to constrict in their cylinders which would result in stuck movements or lack of adequate pressure to facilitate smooth gear changes. You may have to replace the valve body. Car doctor. |

billionjoys: 1992 car? 23 years? What do you expect after so much mileage? Gearbox should be due for change if not maintained properly. BTW, what's the mileage? |

Re: Automatic Gearbox Problems by cardoctor(m): 10:31pm On Aug 19, 2015 |
rosco191: The Abro you used may have damaged your gearbox. I think its a bit too late. You may have to consider replacing the gearbox. |
Re: Automatic Gearbox Problems by obi2ice(m): 10:56pm On Aug 19, 2015 |
cardoctor: Thanks for your prompt response. Yes they must have been too quick to remove it. Please do you know any good mechanics in Abuja i can go to, preferably a gear specialist, because they are suggesting i change to the 10pin gear. i do not want to do this i need a more experienced professional. And do you know any reliable auto part dealer in Abuja where i could get this valve body. Thanks in advance |
Re: Automatic Gearbox Problems by TOMTOSHO: 1:56am On Aug 20, 2015 |
Hello car doctor, I live here in Lagos, and I drive an Infiniti fx35 (2005). Sometimes in 2013, precisely around august, I discovered that whenever I switch on my engine and engage d gear, there was this little reluctance for it to move, then the moment it moves, it works perfectly until I switch off the engine. I told my mechanic who suggested I change the fluid. I gave him d money and he fixed it (the genesis of d problem). But to my surprise, it still continued after few days, I told d man and he asked to continue using it saying soon it would correct itself. So I continued until it became worse late last year. I have a friend who when driving my car and we get to a traffic point the moment d traffic clears and he wants to move, he would rather have to switch off d engine and restart for it to move immediately. Then I took the car to automedic early dis year, they scanned it and the result showed that 3 or 4 solenoids were bad. They told me they could service it and replace d fluid as well. It was then I knew that the recommended fluid for my car is Nisaan magic fluid J. Cos they showed me where its written on d car. I paid and everything was done but as I write dis piece, d said car is already on market for sale. Cos I can't stand d wahala anymore as d trouble still persist. But I stumbled on dis forum and I like the way u have bn shedding light on transmission issues then I said lemme tell u my plight. Now the question is......... Can you fix my transmission issue? If yes, then how do I go about it. Thanx. |

Hello car doctor and other specialist in the house, I was recently given an Xle toyota camry 2007 to use for personal use and I noticed the following: 1)The acceleration pedal doesn't really go down to the lowest but it later picks itself. 2)At times, the car just raises itself as if it's put on neutral then adjust itself automatically 3)The car makes some shikky sound when I put on the AC, can that be the fan belt or which belt can it be? 4)I think the person that gave me said something about the steering rack. I didn't understand him though. Please advice will be needed. Thanks and God bless. Keep up the good work all car experts in the house. |

Re: Automatic Gearbox Problems by lele007: 5:57pm On Aug 22, 2015 |
Hello Cardoctor, I drive a Mazda 3 2005 model with auto transmission. The ATF is now brownish, sometimes, after extended driving, the car doesn't change thru gears properly, and one day the gearbox warning light came on. So I've bought enough Mobil 1 ATF to do a complete drain and flush, the problem is, all the mechanics I've spoken to don't have a professional autotrans flush machine. Where can I do this fluid change, in a way that completely removes the old, degraded fluid, as opposed to a simple drain and fill? |

lele007: Not sure where you will get a tranny flush machine in Lagos. Even with a flush machine, you will still have some that will remain in the torque converter. So there is no way to "technically" remove all the fluid. What is possible is that you do a like 3 drain and fill and you repeat that may be 2 weeks intervals (will cost you). With that, the concentration of the old oil will be so low that it won't be too noticeable. Even here in the States, people just do drain and fill for the most part and you should be fine. Better to remove the pan. You will get most of the oil out. Fresh oil. Fresh filter. Fresh gasket Good luck |

lele007: This link will absolutely surprise a lot of people as it goes against popular advice, proof that each car and sometimes even each model is different, and when giving advice that needs to be taken into consideration. Mazda recommends flushing of its transmission cooler lines and oil cooler, I have evidence also that Honda recommends the same, but Honda is not the subject of your issue, so I am not going to post the relevant service bulletin. http://miata.net/garage/tsb/05-008-11-2587.pdf Your vehicle falls under the models 2004 - 2012 Mazda 3 except SKYACTIV We have been doing Mazda for several generations and I have subscription to Mazda Dealer Level Information. You have allowed that ATF to degrade too much. You must absolutely do something about it! You must absolutely flush the transmission via the return pipe method, and the transmission cooler lines and oil cooler and to avoid a transmission change. I see one coming within the next 30,000 miles unless you act swiftly on the above recommendation. Extract: Automatic Transaxle/Transmission (A/T) oil cooler and lines must be power flushed completely before an over- hauled or replacement A/T is installed (except SKYACTIV-DRIVE). The most common cause of repeat A/T failures is lack of lubrication to the front and rear planetary gears. This is usually caused by an accumulation of metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power flushing will remove the restriction by back flushing, followed by forward flushing to dislodge a restriction, then back flushing again. This will in turn ensure full ATF flow for the transmission when it is operating. You must absolutely use a high quality synthetic ATF in your Mazda transmission and install an external oil cooler in series with the OEM to protect your transmission and if you please an in-line transmission filter |
Re: Automatic Gearbox Problems by USAutoBuy(m): 11:13pm On Aug 23, 2015 |
IdaraCHODB: With all due respect, you are talking of 2 different things. The guy is not REPLACING the tranny. Bulletin is talking about when a rebuilt tranny or replacement is to be installed. I stand to be corrected |
Re: Automatic Gearbox Problems by IdaraCHODB(m): 11:28pm On Aug 23, 2015 |
USAutoBuy: Yes, he is not replacing the tranny agreed! But he has bad ATF which flows through the oil cooler lines and oil cooler. Especially if he did not use a synthetic ATF. If the tranny has degraded so much, and he doesn't plan on replacing the tranny anytime soon, then i recommend that he puts two and two together, that is, make a learned inference from the above service bulletin. his oil cooler is now clogged, same goes for the transmission lines, in addition to the dirts clogging the transmission itself. So I would flush not with a machine but via the return line method first until fluid is clear, he may need up to 6 litres above normal ATF capacity to get this done THEN disconnect tranny lines and oil coolers AND DO a backflush, a flush and another backflush using fluids and air compressor methods THEN reconnect. if he doesn't follow this procedure, all his new ATF will be immediately contaminated and will turn brown within 5,000 to 10,000 miles each subsequent minor drain and refill without clearing the oil cooler and lines will continually increase the debris until the transmission packs up So true, Mazda didn't say so, but I can infer that he needs to do it or pay the price of a transmission replacement in 30,000 to 50,000 miles. |
Re: Automatic Gearbox Problems by USAutoBuy(m): 11:37pm On Aug 23, 2015 |
if you read my recommendations, he should be prepared to do 2-3 oil changes to get to good oil without a flush. That is even if he can find a flushing machine |

Cooler line flush is recommended for EVERY transmission replacement, which is not the case here. As a fact, many transmission rebuild shops will not honour warranty if it is proven you did not flush your cooler line before installation. Transmission problems risk after a flush is higher with debri-contaminated atf, than just degraded/oxidised one. Drain and refill (a couple times) should do. |
