Your bands are gone, you need to replace them.
A car might stall when shifting from park to reverse if the idle is set too low. It is also possible that the engine stalls because it is not fully warmed up before shifting from park to reverse.
Came up to a stop light and when the light changed the car would not move.
Drive...
yes
If a transmission for a car becomes stuck between 1st and 2nd gear the fluid should be changed. Old fluid in a transmission can cause hard shifting and stuck gears.
Most likely pressure control solenoid in transmission....Easily tested with proper scan tool ALSO try changing EGR valve. Will REALLY HELP!!!! I just changed mine, all my hard shifting and jerking in reverse went away.
bad filter
might be bad motor mount / or electrical short
Try having the ATF and transmission filter changed. If that doesn't help you probably have a failing "valve body" in the transmission.
Sounds like the reverse switch is either damaged, or wired backwards... Did you have your clutch done recently?
bad synco rings
well it could be the transmission bracket or ur motor mounts but im not real sure
