Hi Guys, I've got a fully rebuilt PPG 1st to 4th helical syncro box with a reocurring problem, it keeps jumping out of 3rd gear under acceleration, the builder keeps blaming PPG with what seems like a load of waffle, its waiting for its 3rd rebuild under warranty, so this will be the 4th time he's rebuilt it, I'd have to assume its got him f**cked.

Any ideas on the problem ?

Is it a ppg or a par box? If it's jumping out of 3rd it could be a clearance issue on the shaft or a ball and detent issue. Who is building the box? If you don't wish to name pm me.

Its a ppg box with all new parts, 1st to 4th gearset with ppg main billet shaft.

The builder has told me he has replaced 3rd gear to a ppg 3rd gear upgrade spec? and sent certain parts back to ppg for re-machining? (but it still jumps out of 3rd gear) sounds a bit odd to me since these parts are case hardened and he has had a history of not telling the truth.

I'm not hear to hang shit on him as I'm over that and he's still trying to rectify the problem, I just think he's clueless and this seems never ending.

Thanks Allen, PM sent.

i strongly suggest contacting ppg themselves and talking the issue through with them as well. They are usually more than helpful and are always looking for ways to improve so even though it may seem like criticism, its right up thier alley mate. best of luck and PM replied ;)

Yer that was my next step, the gearset was purchased from ppg by the builder, I've found companys dont like to discuss things with someone else's client but it may be the best solution in this case as its dragging on.

Thanks for your help and your PM, I'll let you know the outcome. Cheers :thumbsup:

Has the 3rd gear synchro hub assembly been replaced? Very common cause of a gearbox jumping out of gear...usually happens on deceleration though.

The gearbox has all new everything Birds, right through, its time I speak to ppg to cross refrence what the builder is telling me.

I have a feeling it could be an interesting conversation. Cheers :thumbsup:

Mate get rid of the PPG crap, I had 2 years of drama's with them.... I would not recommend anyone using PPG products.. Your builder is probably right..

Sad but true.

Mate you could be right but I haven't spoken to PPG yet, only the builder who I've found is not big on telling the truth so I should give them a chance.

I spoke to some guy at PPG and he said Mark will call me back so time will tell, I'm looking forward to speaking with him to get a better picture with whats going on hear or if they even know of my problems.

Sorry to hear about your drama's, we all like to get what we paid for and shouldn't settle for less. :thumbsup:

      49719 is the cooler loop. Right at the front, LHS of that diagram. Return line from rack (LP side) goes to cooler loop on RHS front of car, then back under engine and returns to bottom of tank. 49717M is feed from tank to pump. HP line out of pump is thick rubber, followed by the hard line that runs down to crossmember and runs in parallel (but opposite flow direction) to the LP return line. Nothing goes anywhere near the firewall or interior of car. The closest they get to that is the connections on the rack.

      Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf

      Don't worry about. Just don't try to drive hard enough to make boost and you'll be fine.

      Yes. This has already been said. It is a loop of hardline in front of the radiator. Because.... the pump is on the LHS and the steering rack hydraulic connections are where they always are on a RHD steering rack....on the RHS. The high pressure line goes down under the engine, along the crossmember, like it does on all Skylines. Don't just throw expensive braided hoses/other kits at it. Work out what is wrong and fix that.

      Still got the afm on the intake, clamps are shut tight, only loose hose is the one that goes from the j pipe towards the IACV, since it's next to impossible to find a factory hose and the barbs are different sizes (I'm still using clamps on this hose to try and help it seal on the iacv side) I've ordered parts to make up the hotside of the intercooler pipes, I'll plumb it in and see what happens in a few days I suppose The turbo's internally gated, can I just unscrew the tension rod to let the gate open?
