Check fluid level and color. If good, test neutral safety switch for shorts and opens (use ohmmeter).

i have a 95 k2500 350 just put in a new tranny and less than 90days later there is little to no pressure. Thinking it is a bad pump but could be the ecu thing as well since the previous tranny went out the same way. If you know where to locate it any help would be great! c = 2wd k = 4wd

Sounds like a sticky check valve in the valve body, try using the new synthetic Dexron VI FLUID GM recommends for all there trans's now, it may cure the problem, it is far superior in every way to the old Dexron 3 Click the link for a press release and info on this great fluid, replace the fluid in my 96 Corvette, better shifting and all around performance.

The EMC detected and problem so it's in limp mode, As long as it's in limp mode the 4th and OD will not activate. Take care not to burn up the transmission by running it hard while your in the limp mode.
Your going to have to get the truck scanned to clear any codes and why there are DTC codes. Auto Zone scan for free and most auto shops charge $10.00 to $20.00 to scan sine they want the business.
If you want to clear the codes your self you can put the ignition to the run position and pull the ECM (Batt) fuse out for 20 sec and place it back in then start the truck. It may stall but let it, just start it again and this would have cleared all the DTC code history.
The transmission should be running fine unless there is a problem and the service engine light will be on again and you'll be in limp mode still with an updated DTC in the ECM.
Good luck and hope this helps.
