i had a similar issue, can't remeber the error code number, but took the transmision pan out and unbolted the next part up from that and took that into a transmission repair place. they told me they seen a lot of s-10's and bravadas with this issue. he took out a pin or solenoid out and reemed out the hole it went into and put in a stronger/bigger part in and its worked just fine since then. thats been 2ish years ago
