Well I have been thinking quite a bit now on the fact I will need to replace my lt77 gearbox ! As I was thinking of going the t5 way the costs and tat arsing about the simplistic way is to fit the r380 ? As these are fitted to landies and trucks and are given loads of stick I think it will be good enough to rip 380 ponies through it pulling just over a ton of tvr ??
My question is will my bits fit ie the gear change mechanism ? I have been told the box will fit the prop bell housing and speed thingy with no other mods as these boxes are about 475 exchange this would be a good bet
Your opinions please :-)

Hi Ste,

Enginer1949 is running close to that sort of power through a standard (but rebuilt) lt77 in his super charged chimaera. When I spoke with him at the NEC it was all good.
Having had a rover box and the T5 I preferred the ratios on the rover box. Put some Difflock oil in it and the gear change is good as well.

Ste....... can't comment on weither it will work or not, and that's why I veered away from it, as no-one could answer my questions...... however if it fits the bell housing, then surely the only concerns would be fitting the prop shaft if longer or shorter, getting a linkage to ensure the gear stick is the right position ... life is so simple when you talk about it smile

with regards to LT77 v T5 ...... yes the LT77 has a longer second gear which I miss since having the T5 installed, but the T5 is more precise on gear change and makes the drive more enjoyable overall.

Thanks I have been in touch with these guys they said something about my linkage that they don't have one but not explained enough , I guess I will work this out myself and take the gearbox down to the Landover specialist and make a comparison or see if my linkage will fit straight on to the r380 ?

I have an LT77 rebuilt about 1k miles ago by Gravesend transmissions cost over £500... Open to offers, will come with new oil. The linkage should only need new bushes which you can get from Rimmers or the likes.
