Sad Not Shifting! Help!
I really hope my tranny didn't take a crap but I'm thinking it's what it is.

2005 G35 Sedan, 90k miles, Automatic. Been running just fine. Not troubles with engine nor tranny. Had it sitting in the garage all weekend and when I get it out this morning to go to work, it will not shift and I notice the Check engine light is on. Even when I go over to manual shift the gears on the dash says I'm going up and down but I can feel and see the Rpms getting higher and no shifting. Haven't got it in the shop yet to check the code. Just wondering if anyone has seen or heard of this before.

Horrible tuesday morning.....

RE: Not Shifting! Help!
Two errors codes came up:

P1774 - Low Coast Brake Solenoid

P1731 - 1st Engine Brakeing

Anyone have any experience on these? Going be a sensor/solenoid replacement but not sure where yet.

RE: Not Shifting! Help!
Has anyone every replaced speed sensor/ solenoid or the whole control value assembly on their transmission before that could give me some insights?
