I understand that desire. The 47re is pretty dumb though. The anteater is close but they still can't unlock for shifts, at least last time i checked.

if you are keeping 14+ psi with your current pump then I wouldn't worry about it.

Mine sensor did the same thing, it was a result of a bad sensor. proper operation should mirror actual oil pressure if you have a pressure sensor and not the switch update.

yep

Disconnect the VP44 wiring harness connector completely. Connect pin 6 on the VP44 to battery ground. Connect pin 7 on the VP44 to battery positive. A diagram of the sockets on the VP44 wiring harness connector is included below. The pins on the VP44 will be the reverse of this diagram (a mirror image). Make sure you know which pins are which... numbers are molded on the connector and possibly on the VP44 (I can't remember). You must insure you don't cause any short circuits or make connections to the wrong pins on the VP44. I would also strongly advise you to add a 15 amp fuse between the VP44 and battery positive. As soon as you make the last connection the VP44, it will be ON and ready to go. Attempt to start the engine in the normal manner. If everything is working properly, the engine will immediately start and idle and do nothing else.

Have you tried the hotwire test?

It is just an expensive lockup switch. What lockup issues?

Sounds like the pump then, just odd not to have a code. Do rpms on the dash go to ~250 rpm when cranking?

are you reading codes with a code scanner or just the key trick? any changes to the truck as of late?

Any codes? When you say it won't crank do you mean it does not turn over when you turn the key or do you mean it turns s over but does not fire?

It's in the VB. What you have is trigged by trans temp normally

you eitehr have low fluid or your fluid temp is too high. or the sensor in the trans is bad.

I would also say it is pretty rare to see a VP just up and quit. the vast majority of the time they give clear signs that an issue is coming.
