Hello house, what could be the cause of a recurring gear problem in camry 2001. I changed the transmission system dec 2012 and not up to 6months its already showing signs of packing up again

What atf did you use? Abro?

the type of ATF you you used matters. what is the grade of the ATF you used when you install the gear system last year?

What exactly is the issue with the gear?
You could try changing the transmission fluid for starters, I almost had a problem with mine, I was traveling from lagos to Port Harcourt with my brother who was driving his Nissan Pathfinder, his car suddenly stopped at Okada before Benin, after trying to fix it and it was getting dark, I had to tow him (His car is far heavier and we had a tow rope) from there till we got to Warri to spend the night and fix it at a reliable workshop. the next day I noticed my car was behaving sluggishly and was delaying when shifting gears. I knew it was a side effect of the towing done the previous day.

What I did was I met this mechanic who took out my " gear converter" drained it and the whole gear by dropping the bottom panel of the gear box, and refilling it with new oil. the delay in shift was reduced and after a few weeks it disappeared entirely. Your case however may be different and may require a different approach, but don't just rush into buying a new gear set.

Thanks for all your responses, really appreciate it, d mechanic used one transmission oil, I don't usually see it in open market; the brand name is valvoline dextron II, after replacing the gear initially it was ok until I started observing a surge/jerk anytime I shift to reverse, the Drive was ok then.
He then advised we serviced the gear filter but unfortunately we couldn't get same valvoline atf so he mixed it with Holt atf said the mixture won't affect anything. After the servicing, there was no improvement, I managed it for a while until it stopped on my way out this last week.

This time, gear wasn't changing to 2, meaning you can only drive within your area, the jerk/surge also extended to the drive.

We scanned the car and according to the technician, its one sensor (am sorry I still don't understand the function of that sensor) that's causing the trouble; I changed the sensor immediately, now the car doesn't change to 2 until rpm reaches 4000 but changes normally there after and the speedometer has stopped working too.

* am sorry for any typo error, difficult typing on the phone

Manage the car to OAndo SS at Agege bye pass before Capitol road and ask for Rapheal at the lube bay. They can put an end to the gear issues

dexron II is not designed/acceptable for Toyota camry!.
change the fluid asap to prevent damage to ur transmission gear fibers.......
buy original fluid...and after about 2 to wks of driving..change again with original fluid...that way almost all the bad fluid would hv been diluted and removed

^^^ thanks bro, but do you mean changing the transmission oil alone will put an end to these problems, what about the speedometer issue, or is that another system entirely? will appreciate more responses from the pros in the house. God bless

well..lots of tampering has happened to the car...u said he changed one sensor that u dont know...

@ this stage..am afraid the whole system might hv been compromised..too much fingering/tampering by a clueless uninformed mechanic......

the cheapest option now is to do a transmission fluid change with original toyota atf...check ur manual and be sure they type specified for your vehicle...i believe its type T IV, but check and be sure......
if its type t iv...then buy the it..its in a metal tin..sold abt 7k for 4liters...drain that awful mixture u put in the car and fill with good atf....there should be some improvement after a while [ie if ur transmission hasnt ben damaged by that junk you put in there].....if there is an improvemnet...then good for you...change the fluid again with original atf..you should be good then.

but if after the first change and there is no improvement...then it implies ur transmission is damaged...my advice would be to buy a toks transmission and drop in the car...fill with original atf and u are good to go.

the speedo issue shud be unrelated....am thinking ur mechanic might hv disconnected something as he was fingering the car........clowns!!..na their way b that....icing on the cake

Thanks a lot bro, appreciate your response, let's see if the change of fluid will make any difference, or may be the car is due for a change afterall I don use am now for over 3years

Change the soloniod n master governor plus the filter and use required fluid

erico2k2: Change the soloniod n master governor plus the filter and use required fluid

Please could you explain further on the solenoid change

You can not rush to change the solenoid without knowing which one to change this is usually through a code

Then on the filter it depends with type of gearbox some you have to open the whole gearbox to get to the filter of which if the mechanic is a automatic specialist thats fine to open if s/he is not please dont try it

But some gearbox are easy to get access to the filter you just open a cover

Its a vital Electrical component in you Auto gear system which plays a vital part i n switching ur gear level from 1-2-3-4-5 etc, its a presure pump that forces fluids hydrolike wise fru tiny valve in the valve body(Buttom part of you gear box)there is another part called master governor as well, they can get damaged or the terminal might get rusty, most you get on cars i n Nigeria might very well be the ones which came with the car at birth so it would be a good idea to just change the whole thing,they sell them as set in the US and they aint expenssive.

if the gearbox has a sump like this in the video then it is easy to replace the filter all you need is to take off sump panel and you will see the filter and you dont need to take off the gearbox from the car


then check this gearbox from honda cr v it doesnt have the panel sump these are the types i was saying dont even bother to let a none automatic specialist touch your gearbox, becoz once you want to change oil filter on such gearbox it becomes a gearbox overhaul

they will damage your gearbox in trial and arrea wasting your money and time and you will spend more moeny getting another gearbox
