i have a 2004 titan, when i first start the truck it will go into reverse, however if i drive it around and put it into reverse, it acts like it is in neutral. I have to turn the truck off and back on and then it will go into reverse.

when working it shifts in nice, it spins the tires in reverse

it sat for about 3 months, i hooked up a jump box to it and when i went to start it the gauges were going crazy and still wouldnt turn over, i trickle charged the battery and started, i am not sure this had anything to do with it, but it had always shifted fine up until then.

Wow - no replies yet!? Hopefully someone more knowledgeable will chime in here... but... If it were me, I would start with the fluid exchange:

Did you check the transmission fluid? The "fluid exchange" is super easy, sounds a lot harder to do by reading it... but it's really simple. If you can change your oil, you can do this exchange...

Test the battery, check all of the connections, and try unhooking the negative cable overnight or doing an ecu reset.
Also make sure the fluid level is full and not contaminated with coolant.

sorry bro you need a new tranny at least valve body but might as well get the whole tranny sorry

other than a valve body being fried when i jumped it, could it be anything else?, the code was 1774, low coast brake solenoid, what externally controls that?, is there a way to test without opening up the tranny?

just seems weird that it works sometimes and not others...

also i did unplug battery, and the tranny fluid is clean and topped off

hmmm, ecu reset sounds interesting

Now you decide to mention that it has a code! That's almost guaranteed bad news. The transmission computer is part of the valve body, inside the case.
Try resetting the truck and also make your grounds are clean and intact.
Good luck!
