A340e Sluggish takeoff? Lockup Solenoid Problem?

[George]

what wheel diameter and diff ratio do you use?
speed cut is usually set at 180kmh, and shifting into overdrive at full throttle occurs at 150-170kmh depending on the car

ecu does engine and auto so bridging te1 and e1 flashes
engine light and also od light for auto codes but u need to
make sure od button is off
im not sure if auto goes into limp mode if one solenoid is gone
as this would mean u only get od
u normally get some arrangement of gears but can change depending
which solenoid is not working
also it's sometimes abit hard to see which gear is not there if u got
sticky solenoids which is common
I've replaced afew in 1uz boxes mainly solenoid 2
this is the most common prob on Toyota autos

yep, mates soarer did the same thing, would feel like its taking off in 2nd or 3rd. swapped some solinoids from a mx83 box and it was like new again.

yeah the o/d did falsh and the engine flashed when i had te1 and e1 but didnt take any notice on the o/d, but i dont have any codes now. i dont think it is the solenoids(touch wood) because it would be fine for the first 5 mins then would loose second gear, and when it was cold again would be fine...think it just had low fluid and old fluid....i had 1 -3- od and would take off in od or 3rd depends if od was turned off. and when you pull it back to l it would take off in 1st and click to 2nd and would go to 3rd and d was 3rd and od depending if od was on or off. so yeah made me think it prob wasnt solenoid because i still had 3rd everywhere says it only has 1 and od if there isnt any power to the solenoids...

im not sure about the diff ratio wheels are 15s i had just asumed it was cutting out at 150 cos it thought it was doing 180 cos of the diff difference but maybe it was just hitting the rev limiter i didnt have a tach and didnt change into o/d cos i held it in second which was 3rd at that stage, lol. ill have to take it back out and test it, dont really want to try any high speed runs on the street have lost my licence to many times...

[litldv8]

it's probably not really limp mode it's just the solenoids not working
but if u do want to test the wiring u need to hook up text lights

where do you tell it what your phone number is?
i shout mine at it all the time









couldn't help myself sorry

bit of a update from the auto from hell....i went for a quick drive and was working good for few mins then 2nd went missing again then came back and then went again, and o/d light was flashing again, so i put some more fluid in since it was on the lower side of the hot mark, and bridged te1 and e1 and got code 26 flashed on the o/d light, on way home it was working again and no o/d light flashing so im guessing its the fuild level thats making it lose 2nd...ill keep a eye on the level and see if its going down...doesnt leak and oil on my driveway so does it just burn up or something? i have a oil cooler so its not leaking into the radiator...

whats code 26 aswell? i searched the net and couldnt find it...

[George]

in case you didn't disconnect your battery the code is still there. Check it again. Make sure it's not 62 which is #1solenoid break
Break means stuffed coil or wiring or connection between wiring and transmission socket

there's no #26 transmission code afaik

[orangeute338]

it seemed like 26 because it would go blank then flash 2 times then pause then 6 times then big pause then 2 times then 6 times...but 62 would make sense if thats what 62 means...yeah i had rest the battery and this code came up just as it started playing up again, seems to be ok now i put some more fluid in it tho and the o/d light stopped flashing...ill reset the battery and see how it goes tom on the way to work and home...might need new solenoid....cheers

This may help

64 - Open or short circuit in no. 3 solenoid valve

67 - OD direct clutch speed sensor signal malfunction

68 - Short circuit in kick-down switch

yeah i think number one must be shot since third works but when pull back to second it doesnt always work stays in third. Now just need to work out if its dodgy solenoid or the wiring. Today it was workin on and off would kick back to second then the next time it wouldn't fluid is still good. Do the mv shift kits come wit new solenoids? might put one in while its apart

[orangeute338]

i checked the codes again and i got 62 and 63. so thats 1 and 2 solenoid. it will be working fine then i boot it and it will kick back to second and shift normal, then the o/d light will start flashing and if i put my foot flat again it wont kick back. then i cruise for 5 mins then the o/d light will stop and it will kick back. so im just not sure if the solenoids are dead should they not work at all or will they work and then not work, im thinking if its wiring then it would be more hit and miss, maybe its still the oil level? since i changed the oil and added more it has been better. the level is just above the highest mark when engine is running and just been driving so hot...i can get a second hand valve body but dont want to put it in and then have the same prop if its just the fluid level...i might try putting some more in maybe

[orangeute338]

i went for a drive and checked the voltage at the ecu. When the auto is workin properly i have 12v at s1 when in 2nd and no voltage when in d and od. when it plays up i have 8-9v on 2nd and d and in od.
