So my transmission was rebuilt by Shiftwerks and installed by Certified Performance In Nashville, TN.
truck only has a few hundred miles. Recently it started acting up. It would go into drive and then I would hit the break and have no pressure no movement. Shut engine off and restart it would move until I hit the brake as soon as I came to a stop and I had no movement .Did this several times to get it home .., now there is zero line pressure and the truck does not move nowhere. Removed transmission and inspected converter clearance to pump and pulled pump I don’t see any wear. Have not pulled valve body yet. Fluid level was correct and added 3 more quarts to verify no pressure. Also eventually through code P1810. Any thoughts on what it could be here.
Thank you!

 

when you say brake...do you mean transbrake, or footbrake?
Can't see in your photos...is the boost valve sleeve and its snap ring still in place or did it work its way out

another good test would be to unplug the main harness connector and check pressures that way to make sure it's a mechanical issue and not an electrical issue

 

foot brake. Truck was running just fine the day prior although it did not want to shift until high RPM say around 3-4,000 under normal driving… this was a short 6 miles drive. Next day all hell broke loose.
Unfortunately the trans is now removed and I cannot perform the pressure check you suggested. The initial check right after the no go issues I seen maybe 60 psi in park but within a minute or so went to 0. After several more checks a few days later I had 0 from the start of text. Yes, the boost valve and snap ring are in place. Is this possibly a electric issue? I was going to check power at the connector later today. I found no blown use at the driver side panel of dash.
Thanks

 

if you truly had 0 pressure, it's not electrical.

have you taken the pump apart to check it's condition?
you either have a worn out pump, a lack of fluid delivery to the pump (cracked filter, wrong filter for the pan style and filter fell off, etc), or a massive massive leak somewhere hydraulically

 

No leaks, filter in place, proper fluid level. I have not disassembled the pump as I’m not a transmission guy and scared 😬. Pics of valve body with pan removed prior to tranny removed.

 

Check out Precision Transmissions or Little Victory Fab Co's you tube channel on 80e pump disassembly, Their videos will easily show you how to take the pump apart and look at the condition of the gears and where they sit in the pump housing.

 

Thanks for the suggestion

 

no problem man, worst case scenario, if your pump is trashed, you can get remans for not a huge pile of cash. just be sure you get the one with the correct lube setup, (front vs rear) (pay close attention to what year you have)

 

Yep. Cause if you get the wrong pump everything works fine except no fluid flow to cooler.. found that out the hard way.

 

I know this is kind of old but if you need transmission help I have a transmission shop in Manchester TN about an hour from Nashville send me an email and we can discuss further Kyle9611@yahoo.com
