Please I have an issue with my INFINITI FX35 Gear box. it is hard to go in rear speed. any tip about the solution to implement? I'm thinking may be it is the solenoid or valve issue but I need help. Or may be an oil level issue?
Because I have to accelerate to more than 3000 rpm for the rear speed to take suddenly. ANY HELP??? THANKS

When is the last time you changed the tranny fluid?

Few months ago. I have been working on that car as it had some issues of rust and others. So I had to disconnect even the ATF pipes. But the car was parked for long don't know if it is a new or old issue for this rear speed.
