Got our coach started last week. the coach batteries were dead put a charge to them. Got the engine started but my transsmion code says don't shift.
My guess is I don't have enough juice in my batteries. Also I can't get the tac to kick on.
Please give us more information if we are to be of assistance. We don't know if you have a 30 year old gas chassis or brand new diesel pusher with Allison 4000 transmission.
But, first step is to fully charge the batteries and verify battery connections. That "cures" a lot of codes.
Are the house batteries full? Or pulling down the power to all the batteries?
What air pressure where you running? Was the air pressure alarm off? My guess is without enough air pressure, then the don't shift light should be on!
Yet once you have run the engine about 15 minutes, the air pressure should be well over the minimum pressure required to move the RV.
It is not unusual for the air to bleed down over winter, but when on a camping trip, the air pressure in the tanks should stay above 65 PSI for a 4 day weekend trip with the engine off. If the air pressure drops below 65 PSI during a 2-3 days trip, the system should be checked for air leaks.
Much below 11 VDC, and you will start seeing codes on for the engine and transmission.
Most people don't realize that for all practical purposes, a 12V battery is DEAD when it's at 10 Volts.
If your battery was DEAD, and was that way for the winter, it may be that the battery won't hold a good charge anymore...have it tested.
As mentioned, unless the batteries are all fully charged, you can expect problems....so get 'em charged up first.
Also as mentioned, in order for the best information/help, you need to give as much information as you can about what you have, and the problems. That old addage, "Information IN helps Information OUT" applies here too.

Also the charger does throw more than what a normal battery charge is. Some devices can be sensitive to that. Maybe just make sure batteries are charged good and then reset he computer in the chassis hat takes care of the tranny and engine. Usually all it takes is disconnecting the battery for a short period of time, reconnecting it and everything would be fine.
Good luck.
