I am aware that with the intelligent allison transmission, the gear selector display is wrong, this is just how it is, can't fix it.. the 2c-2l change works by duplicating the gear, and having the torque converter only lock up in 3rd and beyond..
Sounds from @CP100 (FMOD sound pack)
MK1 engine turbochargers from @zschmeez (semi turbos for wentward)
The wentward shows its age by having a mid-cycle engine refresh, with these being the old engines replaced.
Perf stats:
MK1 Engine: 300hp/380hp/490hp/
MK2 Engine: 270hp/350hp/420hp (same as stock beamNG bar the T420)
MK1s come with an allison or voith, and MK2s come with a new ZF or new voith.

Description of the presets:
Fast-City:A Citybus with 420hp and a modified transmission, this thing can fly, it has comparatively little torque to other 420hp diesel engines due to it being rather small capacity (8.9L) The transmission is a menace, dropping from 2nd to 1st at 20mph. This thing will roar all the way to 2400RPM
Base Model with Voith Transmission: This is a basemodel variant with an interesting transmission, using a VOITH DiWA. It shifts out of 1st at about 9mph and 2nd goes until 30mph. Odd, but i'm only playing by what i can see on the internet
Gasoline City: This has the Gavril Tri-Tech (or Poseidon) engine, it can run on 3 fuels (CNG, Propane and Gasoline). It has a very low torque output (600 ish NM) and hence is really sluggish. But a slick 6-speed auto from gavril, tuned to iron out any shift lurches, will keep this thing ticking over and propelling the bus, even if it means a regular trip to 4000RPM and beyond to get the thing up a hill!.
Rapid: A citybus with 950hp, what could possibly go wrong.
Propane City: The Gavril Tri-Tech running on propane has slightly more performance than normal, around 400hp.
2-speed base:This has a 2-speed auto transmission, truly cost saving. Interesting to drive too.
ZF T420 Hiway:The T420 is now in the highway config, and has a ZF ecomat transmission to match, this thing cruises at 1300RPM, and accelerates in smooth ZF glory.

The best bits of the DansWorth, now in the DT40L :)
