Synchromesh (default): Easier speed matching, allowing higher gear steps in some cases. Bigger and more expensive transmissions. Slower to engage gears.
Constant mesh: Requires precise speed matching by the driver. Small and cheap transmissions.
Slide mesh: WWI option pre synchromesh invention and constant mesh use on tanks. The same behaviour as constant mesh but bigger and cheaper.
These aren't limited by era yet.
Synchromesh goes: declutch > shift > reclutch
Constant mesh and slide mesh require the new double declutching: declutch > neutral > clutch > speedmatch > declutch > shift > reclutch
Your transmissions will be set to synchromesh and wont change size.
Other changes
- The driver now only upshifts if the vehicle is capable of accelerating in the current gear and the next gear would also accelerate.
- The driver now only downshifts if the engine speed drops below its operating rpm (+ an estimated drop from shifting) and the current gear isn't capable of accelerating.
- Engine 'Downshift' renamed to 'Operating speed'
- Speed match threshold increased from 50rpm to 100rpm. This gets bumped up to 250rpm if the engine is about to stall.
- Engine friction is now higher in earlier eras and track resistance has been reduced further. Should help with speed matching issues.
- Fixed vehicles not upshifting in reverse.
- Removed the failed shift notification
