Paccar TX12-TX18-TX18PRO Transmissions Pack

Update 1.3

I don't know what happened, but my previous update didn't work. However everything looked good when I looked at the definitions in the files but my latest additions didn't even work. So I redid my last update from a local backup, tested as necessary in the selection of transmissions and everything should be in order now. The 2014 T680 and both 579 on the previous update are operational with the transmissions I added to them.

Update 1.2

Trucks Added

- Kenworth T680 2014 (SCS)
- Peterbilt 579 (SCS)
- Peterbilt 579 Next Gen (Frank Peru)

***********


Update 1.1

Modded input removed from the 2.64 ratio of the new 2022 Kenworth T680, because it appeared duplicated given that the non-modded base transmission already comes with this ratio.

***********

This is a simple mod I've made that adds Paccar TX Transmissions for these models:

Kenworth:

- Kenworth T680 2014 (SCS)
- Kenworth T680 2022 (SCS)
- Kenworth T800 (GTM)
- Kenworth W900 (SCS)
- Kenworth W990 (Harven / Frank Peru)

Peterbilt

- Peterbilt 389 (SCS)
- Peterbilt 567 (GTM)
- Peterbilt 579 (SCS)
- Peterbilt 579 Next Gen (Frank Peru)

Suggestion:
Mix it with an MX-13 Paccar engine and you get something near of realistic powertrain . Example :

Economy:
455HP with a 2.64
455HP with a 2.79
485HP with a 2.79

Performance:
455HP with a 3.08
510HP with a 2.85

I've made this mod after the arrival of the brand new Kenworth T680 2022 by SCS. Without mod, the truck have only one option and it is the 12 speed with a ratio of 2.64. I added more ratio for it as it is available IRL.

Paccar TX 12

Paccar TX 18

Paccar TX 18 Pro
