Defender gearboxes?

Hey guys,

Looking at trying to change the gearbox in my lightweight?
At the moment I have a 2.5 diesel an in and was wondering how much work it should be to put a defender gearbox in?

Thanks

I think you've got to move the crossmember for it to go in. The tunnel also needs modifying

Crossmember needs modifying ....
Defender tunnel and a nibble out of the front edge of the seatbox to enable full travel of the hi/lo lever ....

Ohhh and custom propshafts as you end up with is sitting slightly deferently to a series one .

There are also those that say the sky will fall down and your world to stop turning unless you also fit a stage one axle (CV joints rather than series style )due to the "permanant 4x4 of the LT77

I call bull**** on that one personally after running a lt77 Tdi combo in the Mrs's s2 88" for many many miles including plenty of towing .

Ok it's not a simple drop in BUT it makes for a stonking drive ....ratios nicely matched to the engine ...stronger than a standard series and overdrive .

It's the way my 2A 109 station wagon will be going in the new year ....

I'm doing this conversion right now on my light weight. You have to amass quite a few parts which I now have, just finding the time is the current challenge

Defender LT77 Seatbox (110 type is best), floor pans, tranny tunnel, bulkhead diaphragm, gearbox crossmember, handbrake lever and cable, gearbox mounting brackets. You will also need a pair of 3.54 diffs, or as i'm doing, use a 1.003 ratio tranasfer box and keep std diffs.

Cut off the existing gearbox x-member from the chassis with a spinner, likewise the handbrake bracket. Then its a question of hanging the new gearbox in position and drilling holes for the gearbox mounts and cross member - this is where I'm at now.

Will post some pics when I get chance
