Got the Surf back from the garage after they sorted my rear bearing (only replaced one brake shoe as they ran out of time! But going back in to get the other one fitted
)
Since then (all the way down to the plain and back over the weekend) there has been a bit of a loss of power and a pronounced juddering roughly between 2000 and 2500 revs. Seems to be intermittent – only at mid range speeds and particularly on the back down the revs (i.e. more noticeable when dropping from 3000 down to 2000 than when going from 2000 up to 3000.
As its at mid range speeds (I think) I’m guessing its between 2 gears (2/3rd 3rd/4th?)
First thought was ATF fluid level so checked it with the engine running after running through the gears. It read very low so topped it up at a garage with (‘Dextron II compatible’ ATF fluid – all they had) engine was at running temp and I ran though the gears between every bit I topped up until it was almost at the top of the ‘hot’ mark)
Though it seemed to improve it a bit the problem was still there and when I checked the level later it was a good few centimetres above the hot level.
Could it be too high and effecting the AT working? Would it be worth draining a bit and seeing if it makes a difference.
Is it bad to mix two different brands of ATF?
I also changed the fuel filter as I’m running a high percentage of veg (80%veg/ 10% petrol/ 10% diesel) there were some small floating fats present (despite filtering, dewatering etc. etc.) which is annoying but there you go. This didn’t seem to make a difference either.
Could be lumps from the veg getting through?
Its not an airlock in the tank causing it as I have one of them so leave the fuel cap slightly loose to allow for pressure equalisation.
Checked the air filter and it looks fine.
Had a service from Toyota about 2 months ago including ATF change/ filters etc. – having said that, this was as a freebie after them d!cking me around with the steering recall so can’t say I really trust they did what they were meant to.
Thought about tyres having thrown some weights but as its not constant I would presume that that can’t be the problem.
Could it be anything to do with the work on the bearings that was just donw?
In case its of any relevance, my drivers side aisin freewheel hub refused to turn all the way around to 'lock' from 'free' (it was fully in the 'free' position on both sides though.
I’m going to order a new batch of ATF fluid today and drain and refill to see if that makes a difference
Any ideas?
Thanks
