Sweet EB Member 27 Member For: 19y 4m 6d Gender: Male Posted 30/08/12 04:28 PM Share Posted 30/08/12 04:28 PM HI, I have read on here everywhere about how crap the T5 in when mated to the Turbo engine. however, I have one of the dreaded gearboxes in mine being a BA MK1 XR6T. The gearbox was rebuilt only 5k ago due to a nackered synco for 2nd gear and 5th so I thought that while the box is out I would get the whole thing freshened up.The rebuild consisted of all new seals and bearing along with all new syncros and a new 2nd gear. Up until this weekend, it's been perfect.The issues the started this weekend is that it is now jumping out of 2nd on a down shift. It was doing this exact same thing before it was rebulit but the rebulid seemed to fix it with a nice positive shift into 2nd. It still goes into 2nd perfectly on the upshift and doesn't jump out but will jump out on the downshift. Not every time but more then half the time.The car gets a bit of a work out but I definitly done abuse the thing at all. Never flat change and I think I could count on one hand how many high rpm changes I have done from 1st to 2nd due to not wanting to kill my $2k gearbox. The car has a generic 10psi tune so would be somewhere in the low 200rwkw.I know a T56 will fix the problem but I have spent $2k on this gearbox and would like to get a bit more from it and don't have 4k to throw at it at the moment. The box is under warentee but I get the feeling that once the box is out it will end up being something that won't be covered. Just thought someone might know what it could be so I am a little more informed before I take the car back to the rebuild place.Cheers... Link to comment Share on other sites More sharing options...

'mine was somewhere in the low 200s' stock....maybe contact the mob that rebuilt it and ask what there advise is? Link to comment Share on other sites More sharing options...
