Lost 3rd gear

[Jester350GT]

Driving into work this morning and pulling off a roundabout, shifted into third and got a vibration through the whole car, clank sound and then everything seemed of. Left work and around off a roundabout into 3rd same thing happened but much worse and now no third gear. Stick goes into the gate fine but its like being in neutral. Luckily all others are working. Searching around found lots running FI breaking the braising and exactly the same kinda sound and issue. If it is this am I looking at a full new gearbox?

 

2003 350gt btw

Sounds like 3rd is dead - be careful bits may be floating around the box and cause more damage to the other gears.

 

Simplest solution is a new box

 

 

 

He usually has them in stock

[Mikesding]

bit careless!

Id say you would be looking at a new box yes. Seems odd though. unless you have been treating the box badly I can see how you would have done something like worn the teeth away.

 

I suppose you are lucky by virtue of the rest of the gears are fine which assuming you cant hear anything hopefully (maybe) means nothing has snapped and is spinning round in there.

 

Ive never looked inside a gearbox but could it possible that the 3rd gear "cogs" have somhow come loose and just aren't driving anymore??

 

Where's Alex when you need him, or keyser!

 

EDIT, as I post that up pops 1 of the two!

Doesn't sound to good from your description - you could start with ZMANALEX as he normally has pre-owned boxes in stock - but not sure if the 350GT boxes are a straight swap, but Alex will know.

Maybe?

I lost 1st 3rd and 6th in my old car and that was simply because a gear linkage had come loose.

Upgrade to a CD009 gearbox

[Jester350GT]

Thanks all

Just trying to arrange getting into jm imports and up on the ramps so we can figure out what's wrong

 

Is the cd009 a big difference? And what kinda price? Can't easily find any for sale

[cs2000]

Alex has those too

 

As for the differences,

 

CD008

Double cone synchronizers in 1st, 3rd, 4th

Triple cone synchronizer in 2nd

 

CD009

Double cone synchronizer in 4th

Triple cone synchronizer in 1st, 2nd, 3rd

 

I do believe however that the mountings for the 009 box are different to the 008 one and as such you would need to make sure you get the mountings with the box

I thought a 2003 would have a CD006?

 

I also believe (quite possibly wrongly ) that the synchronizers in the CD009 are a "harder" metal - it is usually the synchro that goes not the whole gear, so maybe a selector fork or pin has gone

 

Hope you get it sorted anyway

[Jester350GT]

anyone with the knowledge of these boxes....Is it worth spending the money getting it looked at by a gearbox specialist, with the risk of the end result being told that I need a replacement box anyway, or just take the plunge and order one?

[Jester350GT]

replacement box in and seems all good. TY to Zmanalex

[glrnet]

Did you go for the cd009?

[Jester350GT]

aye. Fitted at JM Imports without any issues. Now got a box with a 'slight' issue and a slave cylinder to shift if anyone is interested lol
