Gonna get a new box fitted by Chunk but can someone highlight possible reasons why this would happen?

 

Thanks!

well its probably a clutch pack...expensive to fix and you need special tools...so its a recon job at a autobox place @ £1200-£1300...you can try changing the fluid but thats usually when its slipping IIRC...however taking the gearbox sump off will show up any particles...if it has bits in the bottom then yep a band/clutch or similar has burnt up

so a new box would fix this I assume?

new are hard to source and expensive i think i only ever seen 1 for sale as new and it was in the states so post wasnt an option...i think the box nissan used in Z32's are borg warner's...TBH most boxes for sale are going to be used or recon

When I say *new* I mean new to me. So would a recon or used fix the problem?

first try the gearbox diagnostic....check andy p's site or search on here might be something thrown up if you do the check

 

in most cases losing gears means its had it...IIRC you could try changing oil to Lucas ATF not sure which one but i think Andy P recommended it as being bullet proof....failing that its a case of getting a working box off a breaker (cheaper though make sure the previous owner isnt a thrash/track day nutter) or recon (as per +£1k)

Itw weird because 1st and 2nd are fine! Then in 3rd, the revs go up but no speed!

Typical signs of a shot box I am afraid.

It's FOOKED.............well mine was when it did exactly the same thing

Reasons Auto Box Wont Go Into 3rd

 

ahhh that was the question then :) sorry!!! dont know

Yep mine did that to, its the high clutch pack that usually goes, if its not that then the second sun gear can also burn up, but its most likely just the clutch pack.
