I'd stick with the LT95, I love it, can stick it in 4th from about 30 and never have to change ger for the rest of your journey, layshaft bearing in mine makes a fair noise but as I'm doing a full rebuild of the truck I'm getting the box rebuilt by a specialist down south should be about £450 which isn't too bad really. If you decide to go down the auto route I've 4HP22 sitting in dry storage for the last couple years you can have for beer money. Never driven with it myself the but the rangie it came out of drove in to the garage where it got removed (guy decided to convert it to deisel for some silly reason...)
