To all you autos out there I have a question.

I dont know if this is normal maybe you can tell me.

In snow mode gear changes are smooth and acceleration is decresed to aid in traction.

In normal mode there is more power but the gear changes are rougher. eg 1st to 2nd is abit clunkyer.

In power mode the gear change is severe with heaps more power occasionaly causeing it to chirp.

My guess is that it is trying to simulate a manual slaming into second especialy when on boost.

I have discussed this with my mechanic and he asures me that ists all normal. I dont know wether to belive him or not. I have already had to change the box thanks to the pevious owner never changeing the transmission fluid. This is now in a box that has done 40k kms. I asked if the bands needed tightening. I was told no..... Am I getting ****ed around or is all this just normal.

P.s can these boxes handle being driven like a manual. I have heaps of mates saying I should drive it that way but I dont want to **** anything up. I dont feel like haveing to buy another gearbox....

Any help is good help thanx guys......

in snow mode the first gear is disengaged.

when my auto changes gears you can not feel the change unless im flogging it.

but even then it would be very rare that i feel the change other than the kick back from power into 2nd.

i drive my auto like a manual and have for the last 25000kms.

when i drive it like a manual (change gears myself) mine most of the time just fishes into 2nd.

but after all i put mine through my gear changes are soft.

maybe in your replacement box someone has installed a shift kit which would make changes rougher and faster.

power mode maxes out rev range but still shouldnt be rough.

id be checking to see if valve body has been modified.

my 2cents worth :P

As slide said, someone may have put a shift kit in your replacement box that you dont know about. I had the auto (which has since been changed to manual cos thats what I prefer), and I used to drive it like a manual with no problems at all.

I have seen some autos drive a bit funny if they are low on fluid, they sort of wind up and then smack into gear all of a sudden.... make sure it has enough in it. If all else fails, drive it like a manual and if it breaks, I still have my auto box in the shed for sale... :(

thanx man but given that the box was just replased it should still have all the oil in it. the old box used to whine so loud half of newcastle could hear it. this new one is quiet but still abit funny. to be quite honest i really hope it doesnt break it cost me $1800 for the last one.

there is a diagnostic mode that you can run for your automatic transmission, is you do a search you should find the procedure on how to do it .. that will tell you if everything is running ok..

Another thing to do is see if there is another member with an auto that lives close to you and see if you can get a drive to see if its any different..

I've heard of auto beeing picked up (second hand) for as little as $200 - most wreckers just can't get rid of them.

Check out the Group buy section to see if anyone in your area has purchased and installed a shift kit, that will give you a good idea of what quick shifts should be like. The nissan box is a bit quicker than a holden or ford slush box, but your description sound a bit harsh for a standard box.

Personally I like the auto (after the shift kit was installed), catch up with some other autos and ask for a ride to compare yours and theirs.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
