Hi folks.
Got this Camry 2.2 automatic 1993. 220.000km. full sevice manual. Had it for about a month now. No problems at all.
But then suddently yesterday i was driving home and enterede the parking area and hit the rear gear as normal to park the car. But nothing happens.

What the f... i put it in Drive again and the car goes forward. But nothing happens when i put it in rear.
Then i tried to give it som rpm. I need about 4000-5000 rpm and then i humps backwards in steps.
What it happening? I checked the gear oil while in drive and engine running. all full so not missing oil.
I bought a toyota because of the quality but what now? is the gearbox dead now? Dont know anything about automatic gearboxes and neither do my mechanic friends.
(only 5% of the cars in my country uses automatic gears)
Hope to get some help. This sounds expensive?
