I was just driving down the road about 3 block from my shop and the truck didn't seam to be running right. When I got to a stop light at a complete stop my egt's started to climb untill 800 and would keep going but I put the truck in park and they started to go back down, and it runs rough in drive but not in N or park.... *** I finshed driving it back to the shop but I have no clue what is going on.


Also when I turn the truck off I hear kind of a grinding noise from under the truck.... SO maybe tranny went poof?

the tranny going south will not affect egt's unless the engine is under a load. was the rpm above idle when you were stopped in gear?

swalter3

nope... just at normal.... it was sitting right between 700 and 800.

check the harmonic balancer(crankshaft pulley) to ensure it's tight. then check your torque converter bolts.

I'd check your oil level also...

swalter3

oil is fine... what bolts on the tc?

dodgezilla04

from the tc to the flexplate.

trik396

Yes check those bolts... grinding sounds are never good. Sometimes the bolts back out and start to wreak havoc...

dodgezilla04

dont forget the balancer, if its loose, your tone ring will be dancing around and confusing the timing on the truck. you also dont want that balancer coming off at speed!!!!! that would be ugly

will check them here in a min.... could it be a sticking injector? I replaced mine about a month ago with ddp rebuilds and one new one all with 90hp nozzels.

If it is sticking you will have an oil pan full of #2 soon!!!!!!
