There is no codes in the ECM. The truck has an after market Trans pan added at the 30000 mile flush. I changed the spin on trans filter when I change the oil at 86000 mile. The trouble started afterwards this time.

Welcome, I'm Chris (aka Moose).

Sorry for the long delay. We got really busy today. I am just finishing up my shift and just now got caught up. Do you still need help?

Expert:  Chris (aka- Moose) replied 4 months ago.

Hello again Chris here,

I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears your not pleased, or need more help.

Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.

Thanks Chris
