2000 Model Avensis Gearbox

[Ricki01]

I have recently purchased a 2000 Avensis, I have noticed a whining noise coming from the gearbox, I am hoping it is low oil level but thinking it might be something more sinister. Can anyone shead any light on the problem for me, and maybe point me in the right direction as to the cheapest remedy.

If its low on oil, i be having a look to see why. You could try draining the oil to see whats its contents are, ie filings etc etc and refill with fresh oil and see what happens.

Does the nosie appear all the time ? or on over run ? etcc etc

May be clutch nosie or the start of wheel bearing nosie.

If its more of a droneing type noise, you may be looking at a box remove and open up, if it is bearing,i would suggest that rather than replace just the 1 failed bearing, replace all 4 that suppport the shafts. All bearings will have done the same work, so you would have to decide wether to replace 1 bearing and refit box, then sods law, couple months later another fails

With out listerning to the nosie, hard to diagnose, but done plenty of box bearings. See if you can get a toyota dealer to road test it with you in the car and produce the noise, they should have a good idea if its the box bearings.

Good luck.

Noise is there all the time while moving, when stationary there is no noise, at first I thought it might have been clutch noise, but when I noticed there was no noise when starting engine or while engine is idling, so guessed it was box rather than clutch.

I think then that you are looking at a box strip and overhaul. :(

What a pain, was hoping for a cheap fix on this 1, love the car though. Is it something I can do myself, I have a lot of experience of working on other cars?

If the noise goes when you press the clutch with car moving then its more than likely the gear box.This is a very common problem in that age Avensis.I have an 02 Avensis and I had to change the gearbox and this led to other problems.See my recent thread on same

Bear in mind, having not herd your sympton, a common problem is bearing failure behind 5th gear, as you split the box, the 1st gear to remove: 5th gear, can be a pain to remove,broke 1 or 2 in my time trying to remove.

Once the 5th gear set up is removed,you will see 2 of the main bearings, roughly 3-4"dia., these tend to be the main 2 culprits of nosie/failure,but like i said, we strip right down into the box and replace the set of 4 support bearings.

So you will need a tool box, a press for gear removal and refit, bearing puller kit,an angle grinder to carefully cut the inner race from the shaft and then tap off its loaction, a heat gun to expand the alloy case to alloy outer bearing races to be removed with a puller,cos you cant tap it from the other side- but DONT MELT the plastic oil guide.

Ohhh,nearly forgot,if you aint put off yet,this next bit may just clinch it,when you split the gears dont let the synchro's fall apart and when you refit, you have to hold the synchro's together while hammering them down (professionaly of course) :D

Then when you have put it all together, you have to strip it back down,because you have to align a reverse shaft up with a hole in the outer case :D , then when rebuilt,make sure the selector shaft locating guide doesnt roll 90 degress when refitting.

So i take it, you will remove the box and pass to a gearbox specialist for overhaul and get some warranty on their workmanship ??

:D :D

Good luck my friend.

Starting to sound to me like this is going to take a bit more than an hour to do lol, will see if I can pick up a replacement box from somewhere, then I can do this one at my leisure. Thank you for all the advice, will post and let you all know how it goes.

Just been reading through the forums, and this appears to be a common problem, I thought these Japanese cars were the best in the world, sounds to me like they are but for the Renault type gearbox problem, (last car was a 03 Laguna, gearbox after 6 months, then turbo and so on). Surely with their expertise they could fix this problem, and help prevent it happening in the first place.

Another thing I would like to know is, did the Gearbox type change with model changes, or can I put any 1.8 vvti Gearbox on it? Been looking on eBay and there a few on there, but a bit reluctant to buy from there as I don't know what condition they are going to be in. Can anyone recommend somewhere to get one from without me being ripped off, and how much should I be looking at paying?

i used to own a 2000 avensis had it for 2 years no problems but mine was a 1.6 petrol with the 4afe engine sold it with 125k on it,does it whine in all gears or just certain ones?

Whines in all gears, only when stationary does it stop

Dont forget to ask the question, why are they selling the gear box ?...... they wont tell you its nosiey........

You will probably find the gearbox case is the same BUT ...... the internal ratio's will differ, in all my time with the brand, idont recall sseing any markings on the case, so trying to match one on the floor at my feet to see if compatible will be awkward, if not impossible.

If you look on your vin plate........ TRANS will be there some where followed by a code....... C512, C513,C514 etc etc.

The gear box type will be a C51.

C512 - means a c51 box with 2 mods over the basic c51

C513 - means a c51 box with 3 mods over the basic c51 box.

So you can see where that is going, the MOD's can either be simple alloy gear box casting or internal mods, so you need to tread carefully.

Ok ty, will have a look and see which 1 it is then.
