ISUZU NPR TRANSMISSION PROBLEM

2001 Isuzu NPR • 150,000 miles

What are the transmission trouble code definitions for this vehicle? When prompted, the CHECK TRANS light flashes codes, 11, 15, 19, 21, 24 & 35. Thank you in advance.

Lot od codes. I doubt all these items have failed at the same time.

Check all the powers and the grounds to the pcm first before going after any of these. Clear the codes and drive it and if the light comes on, go for the first code showing up as it may be the real and only code needing attention
