As above..gearbox went last week, trying to get hold of a replacement asap.

 

got a 3aa box 07866684617

 

PM'd you mate!!

What is the difference between a 3aa box and a 1aa box??

STILL after a box as the company i ordered from have messed me around. Was meant to be here Monday...making up every excuse under the sun now.

First told they only have 1 in stock and it's a rare box lmfao...then told me today they sent out 4 of the same box...hmm...i smell bull****!!

 

you have pm

 

Need to now find out if it's compatible, i know the 52 in the code means it's an older box. Don't know what part is the ratio - poss the end part. Have to see what the difference is between a 1aa box and a 3aa box

 

no prob. been lookin in posts but cant find a chart. i asked back along how to tell the ratio of the rear diff. since the site change i cant find it mate. anyone know please

that any good

 

AWESOME mate...good work...i'll be hanging onto that for any future reference. As i say this box is meant to be on its way for tomorrow, failing that i'll be in touch!!

 

no prob mate

 

Still after a box with a rear diff ratio of 4.11 guys as the one i bought from JAP CAR BREAKERS!!!!!!! was a stinker!!! Steer clear of them!!!

 

Grade A, get a TY755VN1AA.

Its out a Forester but goes in and uttilises a 4.111 rear diff.

Got one in my scoob.

 

Oh same ratios as a 95 wrx.

 

yhpm

 

VN oh so it's a Euro/British one...

..755 a stronger box than the rubbish 752?? lol the one that's made of chocolate lol...been through two of them in 3yrs, and know ppl with 320bhp+ who have been through 5 or 6 of these weak boxes.

 

Yup same casing and stonger internals as the ty754 except it also has an oil cooler take off. This can be linked out should you want too, I dont as i use mine on track.

Yeah i stripped 3rd on my std ty752 with less than 300bhp.

AFAIK it has a 4.444 front diff with a drop ratio of 1.081 to this is for a 4.111 rear diff.
Other markets have a 4.444 rear diff, dont know why they mess around so much with diff combo's.

Call Grade A they have them on the shelf, It was less than £500 to my door and at least you have a little comback using a reputable company.

 

As you can see it works a treat,
