96 cummins 2500 turbo 325k miles auto.... truck stalls after a long drive at stop or when put in reverse. once on the road runs strong, no check engine light this happen this past weekend. it stalls like your in high gear when you gotta down shift in manual trans. i manually down shift yesterday after work it seem to wanna stall just a bit but not as bad like it does in drive. idles in park just fine sounds good.

 

forgot to add at 50mph it jumps out of OD in and out until you punch it and get above 55 then it will stay in OD

 

Check for fuel shutoff solenoid moving freely on the pump. If the solenoid does not fully travel, it will give these problems. Not expensive if the plunger moves at all. It's just an electromagnet. Take it off and clean it.

If it is completely broke, put in a push pull cable or even a couple rubber bands. It won't shut off with the key, but you can move the lever manually.

 

ok i dont have the truck with me but i'll check that i did replace the fuel shutofff soleniod last year as i had to push up the plunger to get the truck to start

 

Hate to say it, but it almost sounds like your Torque Converter is not unlocking when coming to a stop.

What does it idle at warmed up in gear?

 

truck idles @ around 7 then when i put in gear at 500. I've been told maybe the governor solenoid is going out? and to drop trans pan, check for metal shavings if so, then it'll be the tc.

 

Before you go doing a bunch of stuff, get that Idle RPM up to 750-800 warmed up in gear.

10 MM wrench and small hands, then see what she does.

500 is WAY low......

 

well i finally drop the pan and sure enough i had more flakes then the guys had in junlge on Gold Rush haha so gonna get the whole 9 yards rebuilt luckly my cowrk has a buddy that will do it for a good price. thanks guys for your help, i'll get back to you all later.
