| Was accessing some parts at a Local KW dealer, saw a Sign in the parts department but did NOT have my Phone. Cummins Announced as of Late 2026 into 2027 they will NO LONGER OFFER any form of Manual Transmission Coupling designs. The Engines will be configured to accept ONLY Two Pedal Automatic Transmission Systems, NOTHING Using a Clutch. |

| Self Defeating system, produces more that cannot compete nor adapt. Will not be driving anything to that level any further as will stick to my old junk for the next decade(s) as likely are my last. |

The new auto shifts still use a clutch. Just no pedal. The Allison fluid drive automatics do not. So your 3 choices right now are standard trans, auto shift trans (standard trans but no clutch pedal) or fluid drive automatic same as car. In our International trucks that is the Allison trans (5,6 or 7 speed). They work well but harder on fuel. We still sell a lot of 18 speed standard shifts but mostly for gravel guys. The 18 speed auto shift is also popular. The Allison option is the most expensive.

| 2 friends that farm have automatics or autoshift trucks. I don't know specifically. But ones a freightliner he has been having problems with electrical stuff related to the transmission. He went thru the power and ground wires before harvest, haven't seen him since to see if he got his problem solved. The other one was a Volvo when harvest started his acted up, after the first couple days of pulling battery cables when it acted up so it would reset, he got it into a shop and the guy cleaned some connections and it has been good thru harvest now. That one wouldn't upshift or down shift when it acted up. I think the one day he drove home from the elevator in second gear. |

Computers don’t truly know when to shift, even some people…. I personally love stick shifts. Sad to see them go, but I probably won’t own something that new!!   ------------- 1955 AC WD45 diesel with D262 repower, 1949 AC WD, 1963 A-C D17 series 3, several Allis garden tractors

| Emissions stuff and automatics must make up a good share of tow trucks business. |

| Another oddity of these Is the self destruction if attempt to so much as pull from a ditch with engine off or batteries dead. Mgr for the tow yard shop near here noted as little as 20 feet of driveshaft rotation being pulled from a parked spot or an accident point and the transmissions of note are junk. They do not respond well to said efforts, require drive shaft or axle shafts be pulled to tow in any value beyond engine running. |

| Back in the day, with a manual transmission, if you had a starter or other electrical problem, you could air up the truck, pick a gear and pull them a 100 yards to start them. It was the same way with cars and trucks. And tractors before hydraulic clutches. |

| The early Hydramatics had a rear pump, if driveline turned they made pressure to apply clutches and could be pull started. |
