Hello I have a 2004 Chevy Silverado 3500 6.6 turbo diesel with a Allison Transmission, when driving down the road then coming to a stop it goes into like lump mode check engine light came on had it checked and come back with solenoid C so I replaced the solenoid it ran really great after that for one day then the next day it did the same thing any suggestion on what might be the problem since I've already changed the solenoid.

Hello,
Do you have the trouble code number or definition, some codes are eletrically generated, others are mechanically generated. Gary

P0700 means there is a transmission control malfunction. It is a generic OBDII description code. You'll need an enhanced scan tool that can access the manufacture side of the PCM (powertrain control module) or the TCM (transmission control module) to see what the specific code(s) is/are that are causing the P0700 to show up.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
