Hi everyone,

Im having issues with the auto in my R34 GT-T when it's cold.

When it's first driven of a day, the auto is super boggy like something is holding it back, both in tiptronic and drive.

When the revs get over around 2500rpm, it cruises along a little smoother, but then i shift gear or it shifts itself (in drive), and it bogs again. It happens in the morning when i go to work, and again in the arvo on my way home.

It also makes a whining kinda sound when cold, its not too loud but i can definitely hear it.

It takes about 10 minutes of driving to get it warm and shifting like it should. Once it's warm, life is good.

The A/T light flashes 1 long, 16 short....and i cannot for the life of me find this error code.

Ive searched for a while both on here and google to see if anyone has experienced a similar issue, but most seem to get the sensors go and get stuck in 3rd, and mine does not get stuck in 3rd.

Please help someone...im trying to sell the car and i don't want to to sell it with a clapped out gearbox. :no:

Cheers.

The fluid is about 1500kms old StevenCJR31, level is good and it still looks new, i don't what fluid was used in it last time it was changed though.

and it doesn't smell burnt Moodles2

It's already a tiptronic box thanks Haines

I thought that the box might just be dying because it's stock and pushing out 225rwkw...and i was told from the guys that tuned it that it should die around 220kw...

Does yours get stuck in 3rd for ages then all of a sudden a big shud into 4th?

Mine goes into 4th all the time, i never get stuck in 3rd...mine's just feeling somewhat "restricted" when it's cold.

I wouldnt say it does a big shud, you could be cruising and it will sit at 2200rpm @60kph in 3rd for a while, and then at some random point, usually after 2-3 mins, the revs drop back to 1600 and it shifts up into 4th. You cant manually shift up either. It will only do it once, after that it will shift into 4th normally for the rest of the drive. If i drive it again an hour or two later, the problem doesnt happen- its only if the car sits there a while. It started doing it occasionally but now it does it 9 out of 10 times in the morning when i drive to work or home again at night.

My non triptonic 33 box had the exact same issue with the exact same error code. Got worse and worse, now 3rd gear won't engage at all and it's pretty selective about when 4th wants to work.Will just be replacing it as I believe 3rd gear will need new clutches, belt or maybe both.

I also have this transmission and have the "get stuck in 3rd and wont go to 4th for awhile" but I've put it down to just heat, it just won't go into fourth until warmed up.

I noticed this way more when I got a much, much much larger AT Cooler installed by MV autos, and it doesn't have a thermostat. Meaning it takes a lot longer to go into 4th and if cruising around on a cold day will actually shift back into enforced third due to the fact it gets too cold. Dunno if that is actually what is occurring but it seems to 'fit' with my limited understanding of it all.

Thats actually what I was thinking- that it may be temp based.

Hopefully its not an issue in the longterm and causing damage to the transmission! The transmission cover over the shifter looks like its been removed at some stage as its a bit worse for wear. Dont know if a transmission cooler has been put in though, I have also heard that a solanoid might be on its way out and causing the problem.

This is, according to google, a pretty common problem in r34's but there doesn't seem to be much info about what is causing it and how to fix it...

I have seen a few english translation user manuals on ebay, I wonder if there will be any useful info on tremah's probelm in there?

Yeah mate, sorry to hijack your thread lol. Wasn't trying to go of topic. Hopefully its not your transmission crapping itself, maybe take it to an a/t specialist and run it past them.

Is it changing gears smoothly?

Tiptronic boxes come up pretty often on gumtree for cheap so if the box is screwed, hopefully it won't be to costly to fix...

I am converting to manual. I had the box looked at, and im the 5th person that has gone into this mechanic with the exact same issue with an R34 tiptronic box. His recommendation was to throw it in the bin when i get it home lol.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
