Welcome to Just Answer I'm Chris aka Moose, I'm sorry you are having problems with your Suburban. I will do my best to help you get this resolved. If I happen to be helping another or step away during our communication, please know I will follow up as soon as I am back available/online. I try to be online for about 10+ hours a day, midday and late-night shift. - Do you have a pressure gauge so we can do a line pressure test on each gear?

Sorry I do not have one
Automotive Expert
Does this remanufactured transmission you installed, come with a warranty?

Automotive Expert
Thanks, It may be best to let a transmission shop diagnose this since you do not have the tools needed. If it is full of fluid, the shift cable is adjusted correctly, all connectors are plugged up. It should at least engage into D and R if there are no concerns internal with the pump and clutches. We need to know if the pump is doing its job by doing a pressure test prior to taking the trans apart starting with the valve body. Thank you for visiting Just Answer, I hope I was able to answer your question. If you need to follow up on this concern please use the reply button. If you like my answer please reply so I can mark your question complete. Moose

If you are on an Android phone or work computer. They can block files from being able to open and or not have Adobe PDF reader on the device. Try opening the file on a computer with Adobe or through the emails you are receiving or from a tablet.

Got itI don't understand the chart, I see 5.3L but what pressure I need
Automotive Expert
See step 3. The chart only applies to the pressure readings when you are commanding the pressure control solenoid shown in step 4.

A compression tester is for air pressure, not hydraulic pressure and it will not have the attachments you need.

I need to go back

That should work.

What all can I ask about my truck

I connected the line to the port on the Driver side and it's hasn't moved
Automotive Expert
So you are saying it is showing there is no line pressure being made by the pump in any gear?
Automotive Expert
No line pressure can mean: - low on transmission oil - The pump is cavitating from the filter not being secure or it is cracked - faulty pump - cracked pump - pressure control valve stuck open and venting all made pressure right back into the pan. The transmission needs to be removed and taken apart to inspect, repair, and overhaul.

Glad to help
