I understand I don't park in gear. I am talking about doing an air brake test you know when purging air to see if your parking and trailer knobs pop out when they are between 25 and 40 psi. Well with a manual trans you would put in 1st gear turn off engine and pump down air to make sure they pop out. With an automated it will roll. I would use chocks but wondered what an umprepared driver would do. I don't and the good Lord willing own an auto
That's another issue with my mDrive...sometimes when you try to put it in N after you back in a spot, and occasionally when you're trying to do a pull-up to straighten out...it gives you the Mack middle finger (looks like a lightening bolt) and refuses to shift into/out of whatever bind it's in...sometimes you just have to shut it off...then get the "neutral not secured" message, and bingo...it finds neutral. Mack has looked at it and says nothing is wrong.
Boss bought an 07 Freightliner M2 with the MBE900 engine and MBT660-60a transmission. Biggest pile of crap I have ever driven. Right now the truck is in the shop because the transmission likes to go into neutral between 2-3 gear and hang out in neutral for a while. Our local shop looked at it and basically said NOPE! We aren't touching that! Why he is so dead set on automatics I will never know. Third pedal forever!
Tanker with automatic means overheating the clutch if you try backing up hill more than once to position the trailer. Just my recent experience with bulk liquid totes. Modern Marvel's are crap.
Those older automatics are a real pain. The new ones, especially Volvo, are a dream to drive. I pulled Black Mountain with a loaded liquid tanker and the Volvo did all the downshifting and at the top of the mountain it upshifted just perfectly.
I saw on truck paper a while ago an older Marmon sleeper truck ex government truck with bullet proof glass and such. That thing took a long time to sell.
