Another question, have Alison ever manufactured a gearbox for a double decker bus and where would you find such an example?

And finally, what is your favourite gearbox? Would be interested to know peoples opinions!

Cheers

Sadly the DAF SB220 is no longer manufactured, although its replacement the VDL SB200 still is, and can be specified with a ZF gearbox if the operator/dealer wanted to specify it from the manufacturer directly.

Again it's down to the person who is purchasing/ordering the vehicle as to the type of gearbox they request, and yes some deckers like the Foden NC came with an Allison gearbox, also some AEC Routemasters that were refurbished with Cummins engines have the same engine and gearbox as the Dennis Dart.

I'm quite a fan of Allison gearboxes, they give you the opportunity to hear the higher-end of the rev scale in most applications (as an enthusiast point of view), without me rambling on for hours I'd say my favourites are the Allison AT-545 & T280R and the ZF Ecomat 4HP500, 5HP500 & 6HP502C.
