I'm new around here, not a Volvo owner myself but I have a friend with one that is having some problems.
The car is a 1995 Volvo 960 automatic. The problem is transmission related. When the car is put into drive it doesn't move; not in reverse, not drive, not any of the gear selections. All I got from him was that the car was shifting funny, then he stopped somewhere, and now it doesn't do anything. I took a look at it, and checked the codes. Only code retrieved was 2-3-5 from port 1. Car starts and revs no problem, but doesn't engage in any gears, but will shift from park to neutral so it can roll. Reverse lights also come on when car is shifted into reverse. Car has been leaking trans fluid for a while I think, as the level was low after it was brought home. I want to assume the worst and say the trans is done, but he just got back from a 200+ mile trip and had no issues, and the trans hasn't been slipping or acting up at all really. Also he's been having problems with the shifter not leaving park without hitting the override button (faulty solenoid). Any help would be appreciated.
