P1886: new solenoids, good grounds, good volt @ fuse, help!
1996 blazer 4wd 4.3
I replaced the solenoids, checked all the grounds and wiring @ the harness, had the right voltage @ the tranny fuse (good ignition switch) and the code is still back!
Anyone have any idea whats going on? Where else can I look?

Well, here's a guy had the same problem..
Trans OBD II Code P1886 Trouble. - Car Forums and Automotive Chat
My guess, if it's not wiring, and it seems to shift fine manually it's probably in the valve body.
Did you recently have a fluid change?

When I put in the new solenoids the code came back immediately when I turned the blazer on and put it in drive. It does shift fine through all the gears manually.

Hello!
95 was PWM .99 Case Diameter 10-15 Ohm
96 was On/Off .89 Case Diameter 20-31 Ohm
Check resistance on Trans.connector between Pin E and S
( 20-31 Ohm or a bit more for a weak internal harness...)
Check Pin N (Range A) to Gnd = Open ore 250k up
Pin P (Range B) to Gnd = 5 Ohm..
Pin R (Range C) to Gnd = Open
