Also while you've got it up on stands changing the oil, see if there's any movement in the driveshaft, at either end or in the middle.
ok will do. Pretty sure there isnt as I did the driveshaft bearing only recently and since have driven it all of 5 mins down the road...and did check for play in the shaft, which there was none. But will check again.
To be honest, i dont think there is anything wrong with this gearbox at all. The OP'er is describing drivetrain chatter from low rpm/light flywheel perfectly. Additionally, buggered gearboxes dont suddenly go quiet above 2500rpm. The noise transmitted into the cabin from a torn or missing shifter boot cannot be underestimated!!!!
I would lean more to thrust bearing than output bearing since it goes quiet when you push the pedal, doing this the output shaft does not change but the thrust bearing gets pressed against the pressure plate which may quieten it if its loose and rattling either from wear or a locating spring falling off. Output bearing would be present whenever rolling and would change with road speed not engine rpm. Input bearing would make noise in neutral unless the noise is load related, does it get quieter when hold speed as opposed to accelerating?
Agree with this as I just replaced my shifter bushes and left the rubber boot loose. Lots of noise in 2nd and 4th and reverse as the boot pulled upwards. Fixed it up again and cannot believe the amount of noise those boots stop.
Its funny any of the oldest type drivers on here usually learnt how to double shuffle on down changes and just pause at the gate for a millisecond before throwing it into another gear. All my manual boxes lasted just fine even racing them, but if you were ham fisted you can beat the syncro in say 5th or whatever the other trick was to put the 80-90 oil in box but put some auto tranny red stuff as well, helped when the box is stiff in the morning and very cold, an old mechanics tip
No one has mentioned input shaft bearing yet? Definitely something to consider as another alternative.
Where did you get that $1500 price to rebuild a box? All the quotes I got in perth were around 3.5k that's auto with a shift kit supply and fit.
No-ones talking auto rebilds here M8. Prices are for manuals. Auto owners are charged so much to rebuild because of additional idiot tax......!!!!!!!!! E
Manual drivers are wannabe boy-racers? Says the man with shift buttons on the wheel, a trend inspired by formula 1. I mean who wouldn't want to play Schumacher (or are you too young for that...) with shift paddles... Anyone with experience on the track or strip can shift a manual zed faster than planetary auto gearboxes of the 80's and 90's, which your SAW-enabled Zed is also equipped with.
I assume when you say "faster" you mean actually changing gears, that may well be true if you time an auto across a gear change from start to finish, but the auto does not fully disengage in the process. But when I say an auto shifts "faster" than a manual I am more interested in the relationship to performance between the car and the ground. I can assure you in that context an auto will out perform a manual changing gears.
Yes by shift I meant change gears - upshift or downshift. Manual vs torque-converter automatic with a planetary gearset. Keeping it relevant to Z32s, manual vs auto is 5-speed vs 4-speed (old gen) torque converter. Greater ratio spread, it's a fair bit heavier, less efficiency... I don't see how an auto zed (with SAW) has any advantages over a manual, without significant hardware upgrades to make it shift faster, and that's just on a drag strip. On the twisties or racetrack, unless the SAW kit rev-matches downshifts, it's at a disadvantage again. Keyboard warrior talk here though. Not that I have actual experience racing/dragging an auto zed, or timed the shifts. But I've had plenty of auto cars before a manual zed. I could change gears in my 2010 navara diesel 5-speed manual faster than my 04 BA falcon 4-speed torque converter auto would change, even with tiptronic (EDIT: ok that's a bit far-fatched, but you know what I mean) (NOTE: tiptronic is not as cool, or fast, as steering-wheel mounted SAW kit)
I rather suspect the those who extoll the virtues of autos over manuals probably dont know actually how to drive a manual. Auto boxes have overtaken manuals for sure. Thing is its not the majority, and never really has been that would choose a manual. They were not as common and so new drivers were forced to drive manuals if they wanted to drive at all. Its just as time goes by, the auto option becomes cheaper and more readily available!!!!! Auto's , not that long ago was a significantly pricier option. C'est la vie! E
Thread = jacked True Tas. New-generation 7/8 speed torque-converter autos are popular on luxury cars for their smoothness etc. Small european cars and high-end performance cars are using twin-clutch gearboxes because they shift at under 0.1 seconds which improves acceleration figures. And these gearboxes with tight 7+ ratios help meet fuel efficiency and emissions regulations. But :br: every day for me thanks.
