hey, i have a 1991 daihatsu rocky (manual) and it is in great condition and never gives me any problems, the other day i drove it and then came home and parked. then when i went and got in it i went to put it into reverse but it wont go into it. it acts like somthing is blocking it from being put into reverse, i tried for about 5 minutes and finally it went in (or so i thought) so i was like hmm whatever and let the clutch out and started pressing the gas and going backwards but it popped out of reverse into neutral. it will not fully go into reverse anymore and i am totaly puzzled. does anyone know what may be causing this and has the solution to my problem? please leave me a message soon as you can because now i have to park on the street and i cant pull into parking spaces at all. thank you in advanced.
