I know this topic has been discussed at length on here and I apologise for starting a new post about it, I have searched and went square eyes reading all the posts and have got myself more confused as a result. I am in Belfast and won't use any of the "gearbox specialists" over here because they haven't a clue and just want to take your money and don't inspire any confidence. The gearbox has had its filter changed and I am confident that it needs rebuilding. It's hanging onto gears and not changing when it should and there appears to be slipping as the engine revs up and speed doesn't increase. My question is has anyone used either of the following rebuilders:-
ECUS
Jubilee House
3 The Drive
Brentwood
Essex CM13 3FR
Quoted £1495 with 24month warrenty

Or
Re-Engineered Transmissions,
Unit p2 freightmasters industrial estate,
Coldharbour lane,
rainham,
Essex
rm13 9bj
Said it would be anything from £850-£1800 depending on what needed replacing.
12 month warranty.

I intend to keep the car for another 2-3 years so I want a good job done.

Any help/info greatly appreciated!

Top place is Mackie in Glasgow Not cheap but the best up to 3 years warranty highly recommend. From experience . 2006 vogue se td6 silver. Bailey unicorn 3 Cadiz . Discovery td5 & many other types before.

I haven't used them, having had 2 rebuilds ( by different garages ) it's important to find the right place.. I used http://www.staautogearbox.co.uk/home for my second rebuild and they know their stuff, there are several members on here that have used them....

But wouldn't it be better to try and find a specialist slightly nearer to say, Liverpool ? Mackie has an excellent reputation and I know that there are a lot of forum members that have used them

Still could be worth asking for a specialist in the Liverpool area.... chances are that most that far north will go the extra few miles to Glasgow  Yesterday I couldn't spell Engineer... Today I are one!

There is Birch services who a few have used in Liverpool. Get yourself down to the harbour and on the overnight ferry to liverpool and a short hop from them or over to Cairnryan and drive down
take the mrs early morning friday and see if they can do a long weekend of it maybe or such? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

If you go to Cairnryan you might as well go to Mackies in Glasgow. John

True I suppose but then I guess Glasgow and Liverpool are probably about the same in terms of long romantic weekend away excuses  FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
