Lovely box the LT95 - not British Leyland btw but Leyland Transmissions, part of Leyand Trucks (as in big trucks) until the formation of British Leyland; wich was our government's idea to kill off some of the finest car makers in the world - namely our own!
The LT95 O/D is only weak if you haven't shimmed it correctly - but that needs knowledge, a brown shop coat, ****** packet and a pencil behind the ear...
All the early 110's had LT95's. The LT77 was then used on IL4 lumps and the LT85 Santana box on V8's. My first 110 - a factory built High Comp 3.5V8 High Capacity PU with LHD, had the vacuum activator for the box fitted down on the kick plate by the driver right heel, next to the high low lever
Early 110's had 2.25 Petrol and Diesel engines, the 2.5 came a little later
All 109's were fitted with 2.25 Petrol or Diesel, IL6 2.6 Petrol and 3.5V8's (strangled to 90 odd bhp)
The 2.25 Diesel lump is an awful engine - truly awful. Thirsty and gutless, it won't pull the skin off a rice pudding; unreliable, short lived.... Just awful.
The 2.5 NA Derv Burner was always a retro fit on 109's - same goes for the oh so sweet and massively tuneable 2.5 petrol
The 2.25 petrol is one of God's favoured engines - it can almost always be bodged to get you home, will run on just about anything flammable, just a great lump.
I'm not a rivet counter but I do like to make sure stuff is right
