I have a 2000 dodge 2500. It has an 02 engine ECM&harness and pcm harness. The truck runs great, but when it is going for lockup the desired gov pressure goes to 845 but actual gov pressure it max of about 410-420. Does any one have any ideas on what would cause this? I've adjusted tv cable from one end to the other. Checked fluid level. I don't wanna sit here and swap parts if I don't need to. Trans is full billet shafts with triple disk. Engine is 6x18 s366
