THE RFA BATTERY IS IN THE REMOTE USED TO UNLOCK DOORS. THE CASE HAS A WATCH BATTERY INSIDE. AFTER INSTALLING A NEW BATTERY YOU WILL HAVE TO RECONFIGURE ALL REMOTES.

the 2nd and 3rd gear solenoid needs to be replaced inside the trans pan

check transmission fluid level,could be very low transmission slipping not going into over drive.if been long time change transmission fluid and filter.if transmission fluid filter already been changed other problems cause transmission not to shift could have worn broken need adjusting.governor valve sticking, governor drive gear worn, governor weights or springs missing or damaged. you could have sticking first and second shift valves.your first and second servos pistons seals stuck or damaged. do fluid change and add some high mileage transmission treatment go to any auto parts stores find transmission additive that will loosen up transmission sticking shift valves in the valve body. if your check engine light is on have vechicle code scan for faulty tps in which will cause transmission not to shift over drive.

I believe there is a expansion valve located on the back part of the air conditioner on the back right side i believe that could be the problem. I think if I am understanding you correctly, your back air is not as cool as it should be or not cold at all. Might want to check this. If I am not understanding you correctly please let me know again what your problem is.

If the car is not going into to drive then the transmission has failed or it is very low on fluid.
