Who did you purchase the trans from? Call them

 

[Mike L.]

Ever think of writing the codes down for reference?

 

[kivetts04dmax]

Well with the harness unplugged it throws p0711 p0763 po748 p0700

You have to get codes with it plugged in. The codes while its unplugged tell you nothing.

Why would you even try it with the harness unplugged? Like Mike L said call the company you purchased it from.

it wont throw codes with harness plugged in and says shift range inhibited. i checked to make sure my pump was workin in tranny and i got pressure coming out of the pump but i still cant shift into any gear. and to everyone who tells to call the pace i got it from... well dont you think that was the first thing i did. if they would have helped me out i wouldnt be on here trying to get some help.

If the fluid level is low it with throw shift range inhibited on the DIC.

We must have codes. We also need the exact order they came out. We have no magic wands and we can not see anything. We have no idea if the clown that built this thing did something wrong.
Codes were inserted in the TCM to diagnose normal problems. They do NOT tell us the answer. They give us an idea where to start looking, Sometimes.
There are no codes written for screw ups. That's when it get difficult and expensive.

lmao...they never do buddy...

Manual valve connected?

Any pressure...perhaps the converter slid forward & results in smashed pump gears in during the install...?

 

[Antiher03]

Did you plug in the neutral safety switch? Or is it on right?

Was the trans actually installed back into the truck?

Haha jk

Shift Inhibited

My 03 thru some codes and it ended up being a valve in the tranny that required the pan to be dropped and some major rework that I had done at the dealer for like $600.00 bucks complete.
I would lose reverse and Overdrive after the tranny heated up.....

Well still no codes but like I said if I pull the bolt on the bottom of trans by the filter and start truck it sprays everywhere but when it sprays out it looks like it's full of air and I have not very much pressure in my lines goin to tran cooler!

 

[Trevor lb7]

Also does anyone know what kinda pressure the cooler lines should have in ten at idle?

 

[xtremebikr04]

Why don't you put a pressure gauge on the port instead of letting it spray everywhere?

He will need a special adapter to do this.

What are you trying to pull codes with? Cheap scanners won't read a lot of trans codes.
