p3nn Posted February 26, 2019 Share Posted February 26, 2019 (edited) Afternoon Chaps, So had a bit of a nightmare yesterday, went out for a spirited drive alongside my mates E36 Track 328i. Going from 2nd to 3rd gear i heard a loud audible bang towards the back of the car.... initially thought it was the diff/prop but seemingly it was the gearbox. Could understand if i was rev matching down/putting a lot of pressure on the box but didn't expect it from 2nd to 3rd. It now appears as if Third gear is non existant. It will slip into the gear fine however if you lift the clutch nothing is there whatsoever and you get a very quiet grinding sound... Double clutching doesn't work... Parked car > Into Third Gear > Lift off Clutch also doesn't engage anything.. Guessing i'll need a new gearbox but any ideas or contacts? Cost for rebuild? Cost for second hand gearbox? Looks like i'll be living the 350z life for a bit longer after dropping the money on this!

ZMANALEX Posted February 26, 2019 Share Posted February 26, 2019 The way forward would be to pull and strip the box to assess the damage or just drop in a used unit to save on downtime. Quote Link to comment Share on other sites More sharing options...

Thanks for the prompt reply. I'm guessing the cost to pull/strip the box would be heafty as it is.. and if i'm doing it at my friends garage he might as well put another gearbox in? Does that sound sensible? Quote Link to comment Share on other sites More sharing options...

As it's a 54 Plate car is there anything i need to look out for? Cheers Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted February 26, 2019 Share Posted February 26, 2019 Is it a box for a 350 or an E36 that you require? Quote Link to comment Share on other sites More sharing options...

cs2000 Posted February 27, 2019 Share Posted February 27, 2019 Having recently done this (i say I... @Keyser and Mrs Keyser did most of the work) its an all day job, even with all the tools in the world at your disposal and a lift. Definitely DIY-able, but if youre on the ground with a trolly jack and axle stands, its a difficult one. a surprising (to me) amount of stuff has to come off Quote Link to comment Share on other sites More sharing options...

We'll have the access to lifts and tools but doesn't sound straight forward from what you say.. Any tips/tutorials/advice? Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted March 4, 2019 Share Posted March 4, 2019 Very straight forward on a ramp and doable in 4 hours if you know your way around a 350Z. Best to have a look at the clutch and fly when you are in there. Quote Link to comment Share on other sites More sharing options...
cs2000 Posted March 4, 2019 Share Posted March 4, 2019 Yeah it’s pretty obvious once you get the car up in the air, keyser marked the prop shaft position and bolts so it went back in the same place with the same bolts, not sure if that’s important. 1 Quote Link to comment Share on other sites More sharing options...
Keyser Posted March 5, 2019 Share Posted March 5, 2019 Do you know I'm not sure if keeping the prop the same place is important any more, It's because the prop is (should be) balanced and back in the day - 1980's (pre my war years ) if you didn't put it on the same way round you could get vibration. The reason for the bolts is they are high tensile - 4 bolts take 300HP - so you don't want to get them muddled up with standard bolts. It's - Disconnect Battery Remove - Interior trim round gearstick then - Gearstick cover plate Gearstick to gearbox holder (can mark the triangle plate as it's position controls the push down point for reverse.) You then remove the gearstick bolt from under the car just pull the square rubber boot off to get at it. Exhaust - I do Cats as well and take of the sensor wires in the middle (colour coded so no need to mark) Prop Cross member (little one) Starter motor Clutch line - take the complete slave off for a DE and hang it from a zip tie saves bleeding the clutch after wiring loom - start at the back remove 2 sensor connectors then all the 10mm bolts holding the clips all the way to the front where you find a long plate going up but again just remove the 2 x 10mm bolts, also has a wire running underneath the bell housing that goes to the CPS and starter. Bell Housing bolts - don't miss the little inspection cover bottom centre with a little 10mm bolt top centre of the gear box is a breather pipe - I find it easier to remove that as well Rear gearbox mount and cross member Pull backwards and be ready to catch I think that's it but I wrote that from memory so I may have forgotten something Good Luck 1 1 Quote Link to comment Share on other sites More sharing options...
