Hi there, where do I start,

 

Old box is toast and just bought a replacement, hoping that it will last a little while until funds can be raised for a manual conversion, I have a UK TT and the replacement box is off an import,

 

are there any decent guides or can anyone help with some pointers before I start stripping the old one off! is this an achievable task or do I need a Dr of car mechanics, I have rebuilt heads and resonably confident with a spanner; however i feel a bit nervious about this one!

Although for a conversion, taking the box off is the same and obviously the reverse for refitting. It should help

Me and some other members off this site did the same thing at the beggining of the year. Its reletively staight forward and i put an import box on my uk car.

 

Drain gearbox oil

remove:

exhaust (studs may break, be prepaired to replace)

first half of prop and centre bearing (mark the prop so it goes back in the same position)

heat shields

gear lever and all plastics etc

starter motor

 

disconnect the wiring loom from the engine bay and leave loose.

 

There's about 10 bolts holding the bell housing of the box to the engine, most are ok to access however the top two are not. You'll need a rachet and socket with about 4 300mm extensions on (no joke) to get to them and you'll need to loosen the engine mounts and then the top intake/intercooler hoses at the front of the engine to get the engine to rotate slightly backwards and get the gear box to hang down giving you access to these bolts.

 

un bolt the dip stick tube

 

Theres then some fun to be had with the Torque convertor and detaching it from the flywheel (if it is a fly wheel?), youll need to access 4 bolts with a spanner on the torque convertor through the gap between gear box and engine bell housings before the gear box gan be dropped and removed from the car. However saying that that might have been when putting the gear box on.................

 

I'll do a search of my old post and find out the rest....

 

 

 

 

*****EDIT

Heres the online service manual gearbox section. Very helpful. This is bell housing torque settings

:rofl::rofl::rofl::rofl:

Holy Crap, Thats the biggest extension I have seen!

 

So I am presuming that other than correct torque of nuts, order, ect there is really nothing to ruin

not really, just print off the manual above,

 

p.s the thing is BLOODY heavy, you'll need a jack etc under it
