Hi guys,

Yesterday my auto transmission stopped changing gears and started slipping in which ever gear i could get it into except for first gear.

In first it feels totaly normal... I can't even get it to change gears properly when i select it.

Does anyone know what is wrong? or does any one have a gear box they could part with cheap?

My only car and I know bugger all about auto's :)(

If anyone can help that would be wonderful.

Thanks

Sounds like one of the bands isn't grabbing anymore. I'm not sure if they break or just slip badly. Did this happen gradually or all of a sudden?

They are pretty much the same transmission from R31 to R34 so an aut transmission place should be able to help you without too much expense.

Are you testing the fluid level when it's hot and the car is RUNNING.

I can only compare to my old VP but i had auto troubles, fluid level looked fine but I was checking it when the car was switched off, as soon as i did while it was running the dipstick came out DRY! :P

Turned out the pipes to the trans cooler where cracked and leaking (the power steering was leaking too so i thought all the dropped fluid was from that) after replacing them and top up it was right as rain.

have you been reving it in netral then dumping it into gear if you have then you are experiancing severe slippage

sometimes if you leave the car off for a while and let it cool down fully it will return to normal :P

im having similar problems with my sigma (shut up!)

start it, rev it moderately to get it to go and it shudders and hops forward a bit, with the sound of grinding, it goes for about 20metres then it disconnects, just like putting the clutch down in a manual. then you turn the motor off and 'let it cool'. then you start again and it goes for a while, then screws itself again. i havent really had a chnce to have a look under it, but i want to tighten the bands and change the fluid. but its at the bottom of a hill and my shed is at the top...might have to tow it back up.

can anyone help me on this? is it purely fluid related, or is it tearing itself apart?

    • Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
    • I'd want at least $40K for mine, but thats easy to say cos I'm not selling anyway.
    • That's incorrect. We have 4 seasons, consisting of pre winter, winter, post winter and a small glimpse of hope!
