Please help Transmission problems

[A.C.COOKIE]

hey I would throw a question out there what could be the cause of getting these codes 66, 67, 81, and 82. I am just wondering if it may be a fuse or if it may be something else as I have just replaced the auto tranny twice now and it keeps giving me similar codes refering to 66 and 81 and has similar problems when changing gears. It does not seem to change while in drive but if manually changed I have 1st and nothing in 2nd then 3rd kicks when selected and visa versa, I am not sure about 4th as i have not been able to get it onto enough of a run. Any help would be greatly appriciated.

Check your fuses, More than likely a 10a fuse is blown, I don't remember location. But it is for Maf & Transmission or something like that.

Did you replace it with the same model VR trans ? There were differences in the wiring connectors between models.

[Brett_jjj]

There are some differences between these auto transmissions depending on what model they came from,They all pretty much look the same physically.The VR autos will have 12 pins in its wiring connector,the VS and later autos will have 13 pins in its wiring connector.These transmissions are not interchangable,although they will bolt straight up no problems,they wont run properly and will set error codes etc..Im not too sure if theres a "workaround" for these differences in the wiring connectors...

I am about to go looking for fuses, and the box I removed was a 5hdd and the one I replaced with is also a 5hdd so hopefully the wiring wont be the problem, cheers for the suggestion I am off to have a play and will let you know how I go thank you guys

[Brett_jjj]

If they are both 5HDD then they will have the same amount of pins in the wiring connectors,so that wont be causing the problems..You mention that these codes keep setting with different transmissions fitted, Id be looking at the wiring from the transmission and around the engine bay, unplug and replug all the wiring connectors to make sure theres good contact between the connectors,and also carefully check the wiring connectors that go to the ECU.It could even be the ECU itself as it controls the transmission.Faulty ECU's are rare,but they can still occasionally stuff up.Id try another ECU as it only takes a minute to unplug the ECU and plug another one in..Let us know how you go with it..

I located a blown fuse under the kick pannel that controll the trans and found that not only was this fuse blown but some smart person decided to originally put in a 7.5 a fuse instead of the 15a that was meant to be there. So I replaced that and took it for another run to see any difference and I have now got all gears but it is now giving me code 83 which is Torque Converter lock could this be caused by insuffient oil levels as the box and TC were dry when I put it all together ?

[Brett_jjj]

Ah,I reckoned it would have been something to do with the wiring side of things.I doubt it would be the fluid causing that latest error code, even if the torque converter was dry when fitted ,it would have filled up with fluid pretty much instantly as soon as the engine was started..and the same with the transmission,any dry fluid passages would have filled up straight away as soon as the engine is started and the fluid is pressurised,and as long as the fluid level has been checked again after it was first started,then it shouldnt be causing the problem now..

[A.C.COOKIE]

ah ok you see I have all of the gears now and it doesnt seem to slip while in gear the changes are smooth up and down but it seems as though it takes alittle more on the peddal to get it to start moving as though its not pressurising as much as it should but not to sure on that, code 83 is TCC PWM solinoid fault which apparently has something to do with oil pressure( according to wreckers that is) so I am not to sure if it would be a fault with the Torque Converter itself or not.

[Brett_jjj]

The TCC or Torque Converter Clutch locks up the torque converter so its a solid connection between the engine and transmission once the car is going above a certain speed and in high gear,usually above 80 k's per hour or thereabouts..Theres a solenoid that locks up the torque converter,so if you are getting the error code 83,then its probably a faulty TCC solenoid..I dont think it has anything to do with regulating the transmission fluid pressures.The pressure control solenoid does this..The torque converter clutch does use transmission fluid pressure, which is regulated by the TCC solenoid to actually do the locking up though..

[A.C.COOKIE]

Um don't want to sound silly but where is the TCC solinoid actually located and what does it look like?

[Brett_jjj]

Ive got a pic here,it looks like theres actually a lockup control solenoid as well as an in pump lockup solenoid .I dont know exactly which one does what,but its gotta be one of them,someone else on here might know though..

[Jacko84]

dont think itd be the pump lock up solenoid, youve test driven it, is lockup activated at 80kmph, before you start changing soliniods see it lockup works then clear codes and see if codes come back again.

[A.C.COOKIE]

cheers for that guys, and I haven't really had the chance to give it a good run where I ve been able to get it to 100 but it all seems pretty smooth within the gear changes, so when I get the chance I will see what happens and let you all know how it goes but untill then your advice and guidence has been muchly appriciated,
thanks again and I will keep you all informed

Double check the harness connection going into the box. Make sure it clicked into posi and u can't pull it out.
