Going west on I-2 hauling a fifth wheel. Suddenly it was like the tranny dropped. Felt like coasting, engine revved up, so let off pedal. Tried to give it gas, twice, no response, so put her in neutral. Still coasting tried to put back in drive, bad grinding noise, so back to neutral. Coasted down a little more, tried second gear, same grinding noise, so in neutral again. So off on the side of highway, left her running for lights. AAA can take ten yrs! Daylight came, checked fluid. It's fine, good color, no shavings but bubbles on dipstick?? Diesel mechanic in Grand Forks says it sounds like flex-plate maybe? Bubbles in fluid, I'm thinking something internal? Any ideas?

flexplate seems unlikely to me. I guess you could pull off the inspection cover and look. I'd say internal but I don't know. Best to get it to a trans shop before you mess more internals up.

Thats all I can give ya, hopefully someone else will chime in with more experience.

 

definatly not good ...................not good

 

i bet it is something to do with the valvebody or the solenoid pack....ive seen this same problem a lot at work...i dont know where the diesel tech got the idea of bein a flex plate

 

WOuld not surprise me if it was the flex plate, someimes you can rip the center right out of them.

 

auto tranny has no flex plate...........................

simple mixup............ifin it was a manual than that would be the problem fersure

 

*scooby doo voice* haaar?

 

Whit... take your meds dude your losing it... Autos have flexplates, manuals have a pressureplate...

 

Um, yeah flexplates are for autos...
