R34 Tiptronic Transmission Problems

[Guest TR34GT]

Hi SAU members.

I have been experiencing another, and an unusal problem.

It's a one problem after another and fix them as I go.

In the end, I hope I'm left with a car that is 100%. Nearly there hopefully.

On the weekend, I was coming back from mums place late one night, and at a set of lights where I was turning right, I floored it, and after taking the corner and accelerating in a straight line, the AT light came on in the dash.

I immediately lost 1st, 2nd and 4th gears! OMG

I limped home, but made it the 20km and pulled into the driveway.

I switched off the ignition, and after the TT shut down, I counted 15 seconds, then re-fired up the ignition.

The AT alert light was off, and I had my gears back.

The car ran smoothly and the tiptronic and full-auto worked fine for the rest of the weekend.

It's now monday morning and I'm doing 130km/hour up the F3, and the light comes on again.

I immediately lost 1st, 2nd and 4th gears once again.

I waited till I got to the Hawkesbury River turn off, then pulled over and shut down.

After re-starting, sure enough, the AT light was off, and the transmission appeared to re-set.

I drove into work slowly along the old road, without problems.

Is anyone else experiencing this problem?

Please let me know.

Many thanks.

Have you checked your trans fluid level? There is a dipstick in the engine bay (right up the back in the centre).

[chook]

run the auto diagnostic and check the codes

[Guest TR34GT]

Colosus.

Thanks for the vote of confidence on my technical ability. LMAO j/k

Yep. Check it once a week.

All has been good so far.

Chook,

Yep. Wyong Automatics are running the diagnostics on the error codes tomorrow morning

No trouble at all coming home this afternoon.

I hate intermittent problems.

Thanks for your help guys.

I'll let you know the outcome, and write up a Car Care Data Sheet.

Ok. No luck here.

The automatics specialist says that the R34 GTT does not retain the error logs for the tiptronic transmission.

Go figure. Are they having me on?

They stated that the only way that I can tell whats happening is bring the car in for a diagnostic, with the problem occuring.

(thats a bit hard when it only happens once in a blue moon)

Any ideas ?

[chook]

It does retain error codes, run it yourself : http://www.skylinesaustralia.com/forums/in...t&p=3605428

quite tricky to activate the diagnostic mode, takes a few attempts to get it right.

possible a shift solenoid by the sound of it ??

with the 33 auto if you unplug the brown electrical plug near your drivers headlight it will lock the trans in 3rd so 1 2 4 wont work

\have a look if you have a big brown plug near your headlight

Geezus wept. That came out from left field.

I'll look. So you are saying that it may be a loose brown wire there, if the 34 is the same as the 33 wiring?

I'll give it a go.

Thanks dangerman4.

ps................the problem hasn't re-ocurred since Tuesday, and I have well and truely been trying to make it happen. And ps again

Many thanks Chook.

It may be that the transmission exoerts don't know how to interface their gear with this particular car.

He said his gear reads only 80% of the computers in various makes and models.

Looks like its time for a new mechanic.

I'll keep trying.

Thanks again.

100% Shift solenoids, get them both changed (A + B) while your car still at least lets you use the other gears and reset the box.

It'll eventually lock you in 3rd forever!!!!

I take it this has happened to you before?

I'll ask the autotrans guys to change them.

hey there sounds exactly like wat im having

but i have already got it stack in 3rd only all the time now

have u changed them solenoids and did it fix it 100%

let me know cheers

Yep it fixed it 100% it's an annoying fault to find as when the solenoids are room temp, they test OK...it's only when you heat them up that you find they have gone open circuit. Change them both and never worry about it again

[OON80]

i had the same experience in my other car (mazda6). turned out to be low voltage from the stuffed alternator. sticking in 3rd was the cars "limp home mode". new alternator and no more problem, but a different car, might be related though.

[666DAN]

Nah it's not the alternator, he's getting the A/T flash sequence as well....solenoids are a common issue with R34's

[W0rp3D]

i know its not the same car but in my nc fairlane i had the same thing, i was told when that happens the auto ecu has put its self in limp mode, it only happened once and when i turned it off and re-started it there was not a problem.

Hi Guys, sounds exactly like my problem, my mechanic found error codes 10 -vehicle speed sensor, 12 & 13 solenoids A & B. I was just about to order a new speed sensor as they said this would be the problem because it was the first error, glad I read this first. Mine started happening after a nice little fishy round a corner about a month ago, now whenever I pull up going down a hill it goes in 3rd until I turnoff and start again. I have noticed if I use manual mode from the start I can stop it from happening so until I get the solenoids changed I'll keep using manual.

Thanks 666Dan for saving me a speed sensor that is probably fine

Mine puts the at light on if I give it some in the rain or on the burnout pad at the drags

but goes out as soon as the speed drops below 5 Km/h

been doing that for over 2 years now

never been stuck in 3rd gear after doing that

only when I installed the Emanage one day it stayed on 3rd

mine does the same thing occasinally when i slide abit in the rain etc.......i thought it might be normal! i guess not

[Dylby77]

Update, even driving in manual mode it stays in 3rd now when its warm like 666Dan said. I'm booking in to get new solenoids asap. I'll let you know if that's the only prob.
