Nothing better than an Allison in a Dart with a Cummins engine. Nice! Such a familiar sound from my younger years. Now Arriva in my area seem to be running these old girls still, thank goodness, but they are now buying more VDL buses with Voith box's. A voith gearbox in my area is a bad idea. They sound great, but they really don't like hills, which is a bit stupid considering you can't really avoid them where I live.

Every comment you have stated about the Allison gearbox, I agree totally, as these features are a common experience on my part. Did you also know that the Voith gearbox automatically selects neutral when you depress the brake pedal, but the Allison doesn't. I can tell because when I put my foot on the brake, the engine idle rises slightly (Voith). I love the whine of the Voith and think the push button selector looks trick.

The Allison transmission whine is mostly due to shape of the gears. The more square the more whine, more rounded less whine. As for the clunking, that is caused by the lockup torque convertor. Allison transmissions take off in non-lockup mode (fluid drive), then transition to lockup mode (direct connection). A 3-speed tranny will alternate between non-lockup and lockup (1/2 gear) depending on speed of vehicle. Going down hill tranny can do full shift lock to lock (whole gear) which causes clunk

@1100HondaCB I have only driven a semi-auto Bristol VR so wouldn't know, but that explains why a Voith slightly revs and goes out of gear when they stop, however on a etrobus yesterday with a Voith the driver actually has to take it out of gear, and the pitch of the whine goes really high and the engine revs go very fast out of gear, this doesn't happen every time it brakes,

The Optares over at Chichester have the MAN engine with the Allison gearbox. They go pretty quick, but are wollowy in the corners. I nickname them shopping trollies because they are pretty nippy and combersome. Chi's Solos are about two years old and some have had new gearboxes already. A new engine costs 23 grand.

I've wanted a bus simulator since last year, but I still haven't got one :( I've only been on a Marshall Capital once, but it didn't have an Allison attached :P However, most of the Arriva NW Marshall Capitals have Allisons. You can find them in Liverpool. The 8/9 route own Dennis Darts and Marshall Capitals. They go across my school road! You can hear the Allison from inside the school! Gratefully, they also go through Huyton Bus Station and you can hear the Allison as is travels past. Amazing!

The Marshall Capital (and Plaxton Pointer and Alexander ALX200 etc) are bodies, the Dennis Dart is a chassis. The complete bus is referred to as e.g. Dennis Dart / Marshall Capital or Marshall Capital bodied Dennis Dart. Optare Solos etc are complete "integral" buses meaning the body and chassis are one

I remember, many years ago, I used to always visit my Aunt on a Wednesday after school. I'd walk down to ASDA with my mum and catch the Arriva 343 to Wallsend. Always an Optare MetroRider with this gearbox, though at the time I didn't know, I just knew it sounded damn good! Sweet memories.
@RWL2012

The MetroRider is also interesting because it uses the 5.9 litre 6 cylinder Cummins B series engine from the Dennis Dart but without the turbo! Still puts out 115bhp, which shows how low the boost is set on the 130bhp turbo version in the 8.8m Mini Pointer Darts. Then for each step up on length on the Dart, the boost is turned up more. The 9.6m Darts have the engine in 145bhp tune, then 160bhp on the 10.1m Darts, 185bhp on the 10.6m Darts which still use the AT545 gearbox, and finally the boost is cranked right up on the 11.3m Super Pointer Darts and the engine is putting out a massive 215bhp and coupled to an Allison B300R or Voith (optional) gearbox!

I dont see why fluid is forced into the gearbox from the torque convertor, at such a pressure to make that noise, it should just pump between the two, The torque convertor creates high pressure within its self drive, and activate the lockup plate (if fitted) but the gearbox creates its own line pressure from the internal pump, There are three pressures in an auto box... Governer pressure, Line pressure and modulator pressure, i dont see what is so diffrent in the AT545 to make so much noise

Correct, this video was featuring this specific model. The Dennis Dart switched to the 2000 series in 2002 and Optare Solos switched to the 2000 series in late 2004 / early 2005 (11.3m Super Pointer Darts from 1998 to 2001 had the B300R fitted if Voith wasn't specified, and Optare Solos from 2003 and 2004 did already have the 2000 series fitted ONLY if the optional Cummins engine was specified. The 2000 series is also standard fitment in the Dart's successor the Enviro200. Some newer full size single deck buses (Optare Tempo, Enviro300) have the T280R as standard fitment. The B300R and T280R produce more of a subtle whoosh than the loud squeal of the old AT545 :-)
