Busted Trans???

[paulzy123]

Hello everyone I'm Paul from the uk.

Been the proud owner of an r33 gtst spec 2 auto in sonic silver for 2.5 years now and i've been looking at upping power.

Went to santa pod raceway this weekend to see what the car would do with some like minded owners sadly things didn't go to plan so to cut a long story short I was on my way home and suddenly lost drive, blipped it and the revs jumped up but the car didn't respond and just carried on doing the same speed. I coasted around 100M to where I could pull off the road, as I did I could smell burning

Jumped out to find ATF down the side of the car and a split hose from my oil cooler, it was still running out.

Managed to organise some ATF and bodge the hose by bypassing the cooler, drove home with tail between legs and took it very easy.

My question is how much damage have i done? any? none? new box? the oil was still nice and red that was coming out but it did pong a bit. once topped up the box "seemed" fine but I didn't take her above 3k rpm.

I'm going to hazard a guess and say I should take it out, get it into third and give it some therapy and see if it slips at all.

Any other suggestions to tell?

I'm truly gutted.

Should be fine if it drove home.

Thanks, did around 100km after. I've got the MV stage 2 quick shift kit, just worried how much life i've taken out of the clutch bands.

You pretty much rolled home and didn't load up the box. You'll be fine.

[paulzy123]

Yea I just took it nice and easy all the way, box seemed fine but I can't help but worry about it, push comes to shove I'll have to get another box beauty of that is nobody wants auto boxes so they're dead cheap. There was a couple on eBay one for £25 and another for £45 where as the manual boxes go for between £500 and £700 !!

I'm relocating the oil cooler tonight to a more suitable position, then I'll get her out and see, fingers crossed......

[paulzy123]

Right, pulled my tranny cooler set up to pieces today and and repositioned it all.

Just topping up the fluid and looking for answers on the net but there's nothing definite so...

do I check the level with the engine idling cold? Or hot?

or

do I check the level with the engine off cold? Or hot?

or all four?? Lol

Sorry there's not many auto owners over here in the uk.

Thanks guys.

Running hot is my guess.  I actually don't know specifically for Skyline auto, because I simply have no care about them.....but I can't see them differing from 99% of other modern autos in that regard.

Obviously you just topped it up, but how old is the fluid? If unknown or old, replace it all with a full synth ATF as it will handle higher temp better.

[paulzy123]

When the line popped I topped up with 3 litres, the trans came back to life, well it got me home driving gently. The fluid was around 20 miles old no more than that. Topped back up yesterday and tried the dipstick when it was warm and idling it was low, barely registering in fact, turned engine off waited five minutes for it to settle and it measuresd perfect for  a hot engine.

So it's a bit confusing, really want to get this sorted so I can take the car out and see if the box is damaged after what happened.

thanks for everyone's input on this, much appreciated.

Your oil is still low. Car needs to be running to check the level.

[paulzy123]

So I put another almost two litres in today bit by bit, box seems fine, got it up to temperature and gave it some beans, didn't slip and it's still going.

 

Thanks for everyone's help :0)
