I have a 2000 Chevrolet Truck Blazer 4WD 4.3L SFI 6cyl

I have hunted all over for my problem and can not find the answer no were.

Very simple,Was driving and all of a sudden with no kind of noise lost complete control of transmission.NO Drive,No Low drives,NO reverse,No bad sounds it just does nothing.Checked the fluid it is clean and good,checked the linkage all works good.What i have seen in a few places is were they talk about the solenoids under the pan.Can they cause all this if 1 or 2 even 3 of them might be bad?

 

possible pump

 

Yes , that does sound like pupm, which means it needs to come out and get rebilt.
