The lack of DMF and the way the defenders drivetrain runs through a lot of 'joints' means that any wear is exacerbated, and as above the driving style isn't like many other vehicles, there is a knack to smooth driving.
The Low gearing in first means you must decide if you use it, or simply opt for a 2ND pull away with a slightly gentle clutch to bring the drive in. Using first when not needed means a lot of load / unload through the system for no reason. I have been through my defender and simply. Engine (Alive Remap) - LOF CLUTCH - Gearbox - LOF OUTPUTSHAFT - T,box - Propshaft - Axles - One Piece rear shafts / HD Front flanges is a tour of what has been done to solve what is standard issues from one end to the other. And it all works to give a smooth drive, certainly isn't worse than my works transit. Also can be found on Fb, Ytube, Insta & Twitter @4WDSouthwest |

A shame they don't really like pulling away in 2nd very well either though.
Not knocking the Puma's. I love the low gearing off road and laning. But compared to any other engine fitted to the 90, they are jerky and not smooth. I've got an old 19j Turbo Diesel out front at the mo, now that really does pull away in 2nd gear as smooth as anything and shames any Puma. Between my brother, uncle and myself and the farm Land Rover's we have 10 Land Rovers, a couple of Disco's and 3 Range Rovers. Covering pretty much all of the engine/gearbox options offered by LR bar the BMW 2.8 and the Isuzu 4.0 litre. Dynamically the Puma's are a cut above in terms of refinement, road manners, low end torque, standard grunt etc. But smoothness and road gearing they seem not quite as finished a product. Such as pulling into a driveway or a side turning, where they labour a little too much, but downshifting makes them scream their head off (comparatively speaking). |

I like the low first gear. If I'm towing, fully loaded, or both, it works perfectly.
I have done the same as others (clutch, one-piece output shaft, 3 torsion diffs, HD flanges) and I can't say that I notice much slack any more. |

A remap and intake improvements have solved a lot of the jerkiness of my 2.2 TDCi 110. Next up is the half shafts after Christmas. You have to remember it's a Defender by definition somewhat agricultural.

There are loads of clonky Puma’s out there, not to mention dealers who will tell you “they all do that” but they don’t. I have driven quite a few good ones. After a bit *cough*( a lot) of work my 2.4 suffers no backlash whatsoever, changes smoothly both up and down through all the gears and pulls away cleanly with no hesitation in both first and second gear. Now if I ever do suffer from any of those issues it is because a part is on it’s way out or something has broken. As others have said you just need to work your way through the truck. I would also suggest taking it back to Gary to tweak the map. I can tell you from personal experience that neither BAS or TD5 inside remaps suffer with the issues you mention, and although i havn’t had an IRB one I doubt it would either. WARNING. This post may contain sarcasm. |
