Today I noticed when I’m in second gear after cuming to a stop at a light I attempted to push the gas paddle down and the truck didn’t move it didn’t make any noise or anything the gear indicator had 2 with flashing down ward arrows  ^ on the left side of the 2…any idea of what this could mean?

Its a automatic 10 speed ultra shift…basically what happened to have me assuming it might have a issue is I took it to Ohio to the mountains tried to take it up a steep incline I was weighing 79000/8000 and it struggled to make it up kept dropping gears at one time it displayed a flashing F the gear display went blank for a second I started sliding backwards I lost power kept my paddle to the floor and other foot on the brake to prevent rolling completely then i regained power gear indicator stayed in first gear and gave me hell trying to make it to the top of the incline couldn’t much get it pass 3 gear indicator would blink different numbers then lose power a little after I made it up I got emptied and I still struggled a little bit when it came time to go up even the slightest incline. The day before all this happened I noticed it didn’t seem like my truck was giving me as much power as it could it would get to 10 gear but It seemed to Be topping out at 70/75mph (bobtailing) it’s my first truck first automatic and first Eaton fuller ultra shifter so I don’t know if that’s normal or not and want to make sure I didn’t make a bad investment its high in miles 1,300,000 but so far thats the only thing I’ve noticed drove it from NC to Ohio and ran there for a week and back to NC it did the flashing F thing once more but seemed to drive better back then it did going to Ohio 

How can I tell if my transmission is in good shape in my 2006 mack vision (Eaton Fuller Transmission)Does it have a computer test input where I can hook up to and test it?

I have a 10 speed automatic 2006 Mack vision and it doesn’t seem to go as fast as I feel like it should I’m topping out at like 70/80 mph it also takes long to build up speed is there anything I can do to fix this issue 

I have a 10 speed automatic 2006 Mack vision and it doesn’t seem like I’m getting much power I push the gas paddle to the floor and it seems like it struggles to get to high speeds and want give me more then 70/80 mph is there anything I can do to speed it up or correct it if it’s a issue 

I have a 2006 Mack vision automatic 10speed and it doesn’t seem to be goin over 75/80 like it’s struggling to get speed gas paddle to the floor and doesn’t give what I think it got any ideas on this situation/problem
