Hard to say, start with the basics-is the fluid full?
I had my 00 eclipse gt automatic do this. took it to mr transmition and they cleared codes that popped up and it stopped. if i drove forward for a while and warmed the car up, then reverse would work. hope this helps.
Check transmission fluid and fill to mark on dipstick. If this doesn't help, expect to replace the transmission.
Check the transmission fluid for odd color or smells. If all of the forward gears work ok then the transmission fluid may not be flowing properly through the valves. The filter could be stopped up, or the bands for reverse could be worn.
It probally is the transmission or your brakes could be slipping.
13bn771g729 shuts off when put in reverse
Its probably the actual transmission itself. It happened to my moms 99 Kia sephia and then it just started working for a few months than the tranny just stopped working all together so I would suggest getting it checked out
Drive 1 locks the automatic transmission into first gear (preventing an upshift). Very good to use when parked or stopped on a very steep slope and you need to move forward and do not want the transmission to shift. Drive 2 locks the automatic transmission into second gear. This is sometimes referred to as a "snow" drive position, as it causes the engine power to be applied to the wheels much more slowly (via converter slippage within the transmission) minimizing actual wheel-spin when accelerating from a stopped position.
air intake more than fuel needs reconfiguration
It is not a good idea to drive with two feet on an automatic transmission unless your stopped on a hill. In that case you would press the brake with your left foot and the gas just a little with your right foot.
Low fluid level, stopped up filter, or a very serious transmission or torque converter problem.
the O ringseal is not in right, the pump is sucking air
Had same trouble with my 04 Sequoia.. Flushed and change transmission fluid and had no more trouble..
