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:

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      After market rear camber arm adjustment

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      By Duncan · Posted

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
