I just bought this 2004 isuzu npr with automatic transmission.
but theres a problem that I cant tell what it is.
the truck starts perfectly fine, when is on R (reverse) is good. P (parking)is good.
when I put it in D (drive) it wont run, when I put 2 (2nd gear) wont run either, When I put it in 1 (first gear) truck runs once the truck is running over 10 rpm all gears work (1) (2) (D). When I get to any stop light and I put it on (D) wont run I have to start with (1st gears) and changing gears while truck starts running.
any suggestions or answers to this problem?

You have something locking up in the trans. Possible the planetarys are broken. You will need a trans shop to check it as it will have to come out and be inspected
