Avensis 1.6.. Can you adjust clutch?

Horse1920

Hi,
Quick question.. Can you adjust the clutch in a Toyota avensis 1.6 vvti 2003 new shape or is it just go get a new one if it's slipping? Thanks in advance

It's a hydraulic clutch with no adjustment. If it's slipping, you'll need to replace it.

Could be air in the line or a leaking master/slave cylinder too.
I'd check the fluid level, bleed out the slave cylinder (and probably brakes too while I'm at it) top up the reservoir and if problem persists and there's no fluid loss then I'd think about the clutch being worn.
Also check that the pedal can fully extend, they can get blocked by mats.

Any of those problems would cause clutch drag( difficulty changing gears). Clutch slip can only be sorted by replacing it.

Ah right yeah, never realised the difference. Yeah if it doesn't stall in second then itsa goner.

It's weird, got up this morning and no slip! Drove it 20 minutes to work and no problem, I never had any grinding ever so I'm hoping it's not the gearbox. I thought Ok maybe it's cold and getting a better bite.. But gave it the full shoe after 20 mins driving and it pulled away in 5th like a train.. Now the Lad that had it before me drove very slowly and may or may not have been riding the clutch for years... Is it limbering out or? Thanks for all the input

From a dead stop on level ground engine running; release the clutch pedal, no accelerator in third gear it should stall. If it doesn't it's toast.
Repeat for second gear, depending on engine torque and clutch condition it may stall or not you'd know best most likely to be the judge.
If it stalls in second and third it's fine, then try post #3.

could be that something has leaked into the clutch, gearbox oil or something, and was causing it to slip?

Not a mechanic, just a humble car diy-er

Right, stalls in 3rd, stalls in second, slight overrev in second under medium/hard acceleration nothing serious, but pulls like a train from 60 to 80mph with no overrev that I can see or feel.... Also it has a Slight shudder in reverse up hill? Anyway I think I'll take it to a garage man tomorrow I think it's not something that I am going to tackle myself there was enough language with the water pump! Thanks for all the info guys

Sounds like there's life in the disc yet. Reversing uphill isn't the best idea, it's like 2½ gear when you think about it. Sounds like a leak/air in the system imho. Check the brake/clutch fluid level/colour is topped up and no obvious drip behind the pedal (master cylinder), or beside the flywheel bellhouse (slave cylinder...sometimes they're inside the case...real annoying..would explain the slipping)...or see if there's a stain on the driveway after you pull away. Or go ahead and try the mechanic they ought to make short work of it unless the slave is in a silly place. If they don't find anything ask them to renew the fluid and bleed the lines...it's anhydrous...only good for a few years the black/browner the worse for wear (it goes squishy) however dark it is in the reservoir it'll be 5 times darker at the end of the lines.
Is the brake pedal traveling a lot?

I feel your pain, we dropped an engine on the water pump once...snapped lifting chain link. That was two days of swearing until we convinced the culprit to buy a new gasket :rolleyes:

Sorry mate but I would have thought having your bluff called once in the thread should have been enough for you. The bulk of what you have posted is totally irrelevant to the symptoms of the OPs problem.

The only part that makes sense is that there may be some life in the disc yet though if it appears to be slipping in 2nd gear then that life wont last long.

As has already been pointed out to you, leaks, faulty fluid, etc, would cause drag and difficulty changing gears not slippage.

The slave is outside the bell housing on these and rarely give any trouble, same goes for the master.

The OP will have to make a call on the basis of the test he did earlier today and decide whether it should be replaced or not.

BTW, I don't know what the question on the travelling of the brake pedal has to do with a clutch problem.


Sorry to all if this is sounding harsh but to be honest, there is no point whatever, in posting in this forum with answers to problems which amounts to "technical guidance", if you are not 100% sure you understand the problem and the solution.

Finally, changing the clutch on these is a tough enough job but is well within the range of a competent DIYer with the proper tools and equipment.

My apologies. Perhaps that was inappropriate exercising of eliminating the least expensive possibility to diagnosis priority.
If the slave cylinder was inside the flywheel case and leaking onto the disc this could cause the same symptom was my logic, and the first place I'd look is the combined brake clutch resevoir unless indicated they were individual pots. I do not know the vehicle, this was just an approach i would adopt to any vehicle. Thankfully you do and have been of more assistance than I with a further diagnosis to proceed from.
