Tonight, coming home from Farmersville, on I30 east of Dallas. Running strong about 80 or so, all of a sudden it was like the truck shifted into neutral. Pulled over on the side of the road and motor was still running, but kinda rough. Still acting like neutral, shifted through all the gears, automatic (forgot to put that in my sig). Still acts like neutral. Decided to try the reboot thing, shut her down and no start, acts like the batteries are low, cranks but no busting off.

Volt meter still shows normal, fuel in the bowl, oil normal, tranny fluid there and shiny pink color (can't check level, not running).

Got towed home, 75 bucks. 35 miles, not a bad price.

No CEL.

When cranking oil pressure gauge does not even try to move.

Could I have lost my LPOP, why would that affect tranny?

Could I have lost alternator, would that affect tranny?

PLEASE HELP ME

Need to watch some stuff with a scanner. It will rev up in gear, like it's in neutral? Definitely strange, but tranny related I would say.

 

[Arisley]

It won't even start now, cranks like batts are low. My first thought was TC or tranny, after I shut it down to try the restart, seems like it might be ALT. Guess it could still be TC though, correct.

I would get some juice to it first then start from there

Something similar happened to me while driving a 95 auto. It would act like it was in N and rev with no acceleration. Then it would stick in 2 and then finally shut off on me going down the road. Turned out to be a bad alt. Also befor it shut off I lost all gauges and radio.

The reason I suspect alternator, is I replace it about six months ago with an O'Reillys Lifetime rebuilt. Had to have it on the road. When the original went out it gave some really weird symptoms. Ran really rough with the headlights on, turn them off and you are good to go.

My gauges all worked though.

Batts on charger now, first thing in the morning, O'Reillys with alternator in my hand.

I appreciate the help guys, keep it coming.

i wold go alternator. with everything being electronic, a bad alternator will mess with a lot of stuff, especially since batteries are low

 

[Arisley]

I am also thinking alternator. I would think that if the Trans went I would get some kind of warning, this thing was running fine one second and not the next, no weird noises at all.

 

[slowleak]

i know your thinking alternator, but in my friends lincoln we had to replace a sensor that detects where the gear shift lever is. his car would randomly go into nuetral, and jump back into gear. it finally got to the point where it would not come out of neutral. but i dont blieve he ever had a problem with electronics.

 

[Arisley]

Not the alternator, just got back from O'Reillys. Also no charge on batts., I think my charger took a dump. Going to run the batts to the PS and have them checked.

Gotta get this thing on the road.

 

[Arisley]

BTW, to add insult to injury, the tow truck was a Duramax. My truck barely fit on it, and it had some acceleration problems, 30 miles at 45MPH.

 

[smorris]

If it'll make ya feel better, I had to go to West VA. last night to rescue a buddies duramax. We were passing cummins going up the hills with the duramax on the trailer..
Pics to be posted later.ointlaugh:

 

[Arisley]

Got the charger working, batts seem to be pretty charged. HPOP full of oil. This thing is cranking slow. Starting to think TC, in the light of day the tranny fluid is brown. But could a bad TC keep the motor from starting? Also, would it not have given some kind of warning.

And yes SMorris, it does make me feel a little better.

Update:

Bad news, the starter engages and cranks (slow, like lots of resistance), the fan does not turn over. No frozen pulleys, everything spins free.

Any one have a 7.3 laying around extra not doing anything? This does not sound good. Have not tried turning the motor over with a bar yet.

But the motor was running and responding to throttle when I pulled over, I shut it down. Locked TC, which broke the flywheel? WAG Anyone heard of this.

 

[Redfish]

Humph.... I can only think of a few things.

The fan isnt going to really turn unless its idling at speed.

breaking a flywheel on a stock truck is near impossible.

I doesn't sound to me like your TC is locked up...

Have you checked all the wiring connections going to the tranny? Its just a WAG

Gear shift cable?

 

[Arisley]

Found it. The flywheel is broken. The starter angages it and turns it but not the motor. How much is a flywheel and where is the best place to buy one.

Broken right at the crank.

 

[Redfish]

Dang.... I wonder what in the heck broke the flywheel... surprised me.

 

[slowleak]

check advanced auto and oreillys. im pretty sure both of them have flywheels

 

[Arisley]

I think my starter did, not sure though. Anyone got a used flexplate laying around gathering dust?

 

[Arisley]

Just got off the phone with O'Reillys, no go.

Will a flexplate from a E40D tranny work?
