hi,
I am having an auto gearbox problem. my surf wants to remain in 3rd gear. if I manually shift to 1st or 2nd the box works great but in drive wants to only use 3rd. it does not change to overdrive. the od off light is flashing on the dash. have had the box serviced and replaced trans fluid. have consulted my local and only toyota dealer for 1000km and they wont help me as surf is an import. unable to access a diagnostic computer. any suggestions?

Welcome to the site

Did Les leave a site card on your window?

The Auto is the same as in the Ausie 4runners, however, the engine wiring, engine sensors and ECU are different with virtually no information available. There is a Transnission diagnostic self-test I have instructions for and you can do. I dont have the info handy for at least another week. I think, but not sure, I sent it to Dandownunder, so if I did, he may be able to assist a bit sooner.

Realisticly, I would suspect your vehicle's ECU (behind pass side kick panel), as it talks to the transmission to do the changing. Try to find a person that has a spare or one for sale on a "didn't fix, no charge" basis and can let you plug it in for a test drive.

Dont let them con you into paying up-front when they say "The problem in your car killed your ECU, so it will kill mine", not much chance of that, go elsewhere.

g'day

one thing to look at may be the level of fluid in the actual transmission.

i have just recently drained mine and put new stuff in and theres a bucket load of difference. main one being smoother gear changes. the stuff that came out almsot looked like sump oil. i have had my surf 2 years, never changed the transmission oil, and being and import, dont know if it ever has been.

you should also changed the filter. but toyota the only place with aprt listing (120 bucks), however, they told be you can was them in mineral turps...


beefy. :idea:

I'd say you have a malfunctioning No 1 solenoid :D but do the the fault code test to confirm the problem.

Had similar problem with my auto surf not changing gears properly.... ended up being an earthing strap missing off the glow plug rail...... check all your earth straps.... the Surfs have a heravy electric load, thus they MUST be earthed correctly....... a autotransmission "specialist" working on mine insisted that wasen't the problem as he had extra earth leads on when he did his diagnostic BUT I insisted after getting advise from a mechanic in Queensland somewhere who had a lot of knowledge on the Surfs.................... 1 hour later the "specialist" rang me back and said come get your Surf... it's working perfectly - after he put the earthing starp where they are supposed to be!

Regards,
Adrian

K & M auto parts in Rocklea, Brisbane do a filter and gasket kit to suit the auto box in the Surf for $25 and keep em on the shelf.......I got one last week. Toyota quoted me approx $200 and a 3 week wait from Japan. Part no. is FK-1690

I don't understand how earthing the glow rail, would fix a problem with the auto transmission. The glow plug rail should not be earthed at all.This will cause a short in the glow plug circuit and blow the fuse resulting in them not working at all.

Thats why he took it to an Auto electrician! He probably wouldn't understand those fangal things!

Sorry, that's not right. The 2.4 Surf has a standard earth strap attached to the engine at the glow plug rail in addition to another earth strap which the location of eludes me at this time. It's not the "glow plug rail" being earthed, just the location of a main earthing strap. There is a substantial post on this topic on the old Forum site detailing the mechanic, auto electrician used sourced from QLD who specialised in Surf's and the reasons for the earth straps being where they are.

Regards,
Adrian

There are three in total,
Battery to body, just beside the battery this is usually the one that gives weird electrical faults. Battery to engine block just under the alternator "main earth" and from battery to inlet manifold to ensure good earth for manifold heater.

there is another earth strap at the back of the motor
also i believe there is a second ecu type unit that controls the auto
but if the earth at the back of the motor is not conected or in poor condition it will cause auto problems i accident left it disconected when i put motor back after snapping a crank
Auto did not want to change connected earth and all was ok

Thanks everyone for all the fabulous information on this site, without it, I'd be quite a few dollars poorer.
This site gives me great hope for mankind as I see how readily people share information and genuinely want to help each other.
I have owned my 1992 2.4 Turbo Auto Surf now for about one year. She has cost me a few dollars, the usual, head gasket (head) radiator etc, but I still love her and she is generally well behaved.
I am struggling with the auto in mine at the moment, but I'll give a quick background first.
I recently changed all the oils, making sure that the auto fluid was Dexron2 etc.
On 2nd Jan, we drove over to Bremer Bay for a week where we did some four wheeling in soft beach sand, but not much.
While over there the auto started playing up.
To begin with, it dropped out off gear coming into town, and then gave a couple of shudders as she picked up third again, She then made a couple of funny slippy changes, made a funny noise when I dropped it into first, then stopped all this bad behavior and amazingly drove well all the way back to Albany where we live.
Then she started playing up again, eventually yesterday, she wouldn't go into gear at all, engine just reves. I can turn off the ignition, then start her back up and she drives fine for a little while then loses gears again
#-o
I've had a good read about possible causes and the most likely culprit seems to be this earth strap/wire to the auto? that everyone keeps talking about. Jez posted this photo on another post - http://groups.msn.com/toyotasurf/egrvsv ... otoID=7347 Thanks Jez.
When I looked for this wire on my beast, the whole wire and bolt was missing, so I'm very keen to locate it and hook it back up. Problem is, I don't know where the other end of this line might be?? There is just no sign of the original wire? Can anyone help?
Thanks
S2

Mate, have a look at the block at the back of the cylinder head on the drivers side , this is where the infamous earth strap is located on my surf, i'd take a pic but my digital camera is stuffed....hope this helps you.

Hi all,
I put an extra earth on but it hasn't helped.

When I drive it now, the gearbox is slipping more and more. It changes alright to start with, but then begins to slip.
It gets to the point when it wont even drive the car forward.
I pull over, turn the engine off and restart it and she drops straight into gear again and drives away (for a little ways at least). I can do this repeatedly.
I think it must have some Windows in it somewhere:-)

It now also makes an occasional slight whirring, almost grinding...sorta...noise from the transmission, maybe the engine end.
I'm beginning to suspect the torque converter or a band perhaps. Has anyone had one fail?
This truck has 130k on the clock and is in pretty good nick. When we removed the head, the cylinders were in very good condition, so I suspect ks are original, not wound back.
I would not have thought the auto would fail on such low ks. I certainly have not given it a punishing. This one has never done much if any off roading before me, no mud, under body dents, sand in sills etc.

Cheers
S2

I would normally say check the TPS as this can make a trans play up if faulty, but it sounds a bit more serious than this. I hope I am wrong.
But check the TPS also do a diagnosis check found in the Tech site under EFI fault diagnosis.
Read carefully to do it properly.
may even be the Transmission computer control module.

Is it any different if you use the ECT Button.

Hmmm ... grinding noise in an auto... transfer case maybe ???
Does it change from high range to low range OK ??

Did you check the trans fluid level with the engine running after you filled it and put in gear to bleed the air, cos it sounds bit like low fluid level or a dodgy solenoid to me.

Next step?
Tried to take the gearbox oil pan off the bottom to have a look and see if I couldn't see anything.
I dropped the oil and was startled to see how black it had become in less than a month, really shitty looking.
Tried to get the pan off but was stymied by the exhaust pipe which had the clamp bolts tack welded!!
I was a bit worried about lying on my back trying to grind off the lugs under the car so just lowered it down to see what I could and had a grope around in the bottom of the pan. There was nothing but the sludge magnets, although they did have quite a bit of sludge on them.
Put it all back together and put new oil in. Drove it this morning for about half an hour and all was well. Parked it in the driveway for a while then went for a drive up the road and she started slipping again real bad straight away to the point she wouldn't move the car, in fact it started rolling back downhill in drive.
Turned it off again, dropped it back into gear and although it is now making quite violent slips from time to time, managed to get it back home aright.
In the driveway when I listen underneath, it definitely has a slight ticking/whirring from the torque converter end of the box.
The transmission oil on the dipstick is now (again) full of microscopic metal filings, just a little glint in the sun.
I've been quoted $880 from the local wreckers for a Surf auto from a head-on with about 140ks on it. And he suggested someone local would charge about $700 to fit it.
Any thoughts?
Cheers gang

Sounds like what happened to Parra's box and it was shagged. The clutches have had it.

$880 for a second hand ain't bad, but $700 to fit is a bit high.
Approx 2.5K to rebuild I think.

Keep looking on other 4wd forums you might find one for sale a bit cheaper and remember that these are not the only vehicles to use the A343F transmission

Thanks Dingo, I'm certainly leaning toward something definitely fried in the box/converter, and not just a solenoid or earthing problem.
I've had a really good read here and no one seems to have slipping problems as a result of the earthing, more changes problems etc.
I've got to get someone to take the job on now. There are very few mechanics in town now, too much work in mining up north.
Cheers and thanks
