General Transmission Fault

my company doesn't staff r/a on nights or weekends. I had to do my own research to get it solved, which I suppose I should be thankful for Google and the internet.

Yeah... THAT makes perfect sense!

(Who needs roadside assistance on nights and weekends???)

We'll, technically we hall Prime trailers so in a pinch I can use their r/a, but my company strongly prefers that we use our own r/a when possible. I imagine it's a professionalism/liability thing when it comes down to truck problems since its not Primes trucks.

So being it sounds like its related to your ignition system @ the key switch? Maybe a loose connector on the tumbler Been ages since I worked on semi's, but I'm athinkin' electrical systems basicly haven't changed too much.

Ignition switches always tend to be the main power feed to hosts of things..... Brand "New" parts of ANY type, ain't always good either LOL

As some of you may know, just under a month ago my 2019 Cascadia with 72,000 miles on it wouldn't shift.

After 3 weeks at a freightliner dealer, it was determined there were no fault codes for the automated transmission, but it had an abs fault, which will cause the truck not to shift. It also had a failed memory bit which could cause it not to shift. They were able to get that code cleared by running an esc test.

They then addressed Recall FL780A ICUC Bulb Check Function and when they fixed that, then the MPC and VRDU were out of calibration so they had to recalibrate those sensors again also.

So I had 2 different reasons the truck decided it wasn't going to shift anymore, an active recall fault, and those pesky sensors were out of calibration again. Of course I've only driven it 35 miles since I got it back and took my hometime, which I'm still on, so hopefully the infamous "Slug Puppy" will be more reliable from here on out.

All the more reason I will stick with my older manual.
