Well I took my 2008 out today and the red tranny light came on.

I stopped and let it cool down and checked codes.

Got 700 and 740.

Looks like my TC is toast or getting there.

I do have a new solenoid pack filters ready for a service since this truck is new to me and I can't afford a new TC so my buddy has a good used one with 200kms on her.

So may pull the tranny this weekend and do this up to see if that makes a difference
