Caddy Gearbox replacement.

[pc.tek]

Hello to all,

I have a 2007 Caddy 2.0 SDI thats destroyed the gearbox, locked up at 70mph. Clutch works, lots of noise coming fromt he gearbox, no drive other than lurching and no gear change unless you are brutal so its a good bet the box is knackered.
My engine/gearbox code are BST/JJS, my question is will a HHN gearbox fit, reason for asking is I have been offered one and been told the gearbox mount and starter motor need changing.

If this could be confirmed to be correct that would be awesome.
Cheers in advance and I am hoping to be of assistance to some one else in the future

Physically they would fit the difference with transmission/gearbox codes is they can have different ratios. I don't know the gearbox type of your Caddy, Golf 0AF Gearbox.

Thank you Keithuk for the quick reply, I have checked the gearbox ratio's and the HHN box is higher ratios which will suit my use of the van.
Box paid for, now waiting for delivery.
I will post and update when fitted

The HHN is for the 2004>2006 Golf 5 2L SDI with a BDK engine, it is specifically only used in that model.

The JJS is (1) 3.45 (2) 1.95 (3) 1.28 (4) 0.93 (5) 0.74 (FD) 4.68

The HHN is (1) 3.45 (2) 1.95 (3) 1.28 (4) 0.93 (5) 0.74 (FD) 4.68

The bell housing used on the JJS is different to the HHN, 0AH 301 107 F as opposed to 0AF 301 107 C, the input shaft is the same though. I THINK you are going to find the block bolt pattern is different but keep us posted.

Hello again, so after a few weeks and a few miles I can confirm the HHN has replaced the JJS gearbox and is bolted onto my BST engine.
I didnt do the work so cant comment on anything hands on but I know the driveshafts and flywheel from the HHN were used, the starter motor and gearbox mount were the same as used with the JJS.
Its a thinner & lighter flywheel so there is a slight difference in driving but it seems more suitable for my usage.
