A couple weeks ago, the temps went down into the teens. When I went to back out of my parking space in the morning, the shifter was very stiff and made a sort of squeaking noise. When I put the shifter in reverse and hit the gas, the engine revved high but the VX wouldn't move. I waited another minute, tried again and same problem. After waiting almost 5 minutes, I was able to go but the shifter was still a little stiff when I put it into Drive. Have any of you had this problem? Now, whenever the temperature is low, I give it a few minutes to warm up before I attempt to move. But is this normal? I originally thought that maybe the tranny fluid was old and not as viscous and needed changed. But when I called the Isuzu place to schedule an appointment, they said they didn't think it had anything to do with the tranny fluid. (They also said that Isuzu feels that the tranny fluid should not be changed unless the vehicle is being driven under extreme driving conditions....whatever that means. I've only had the vehicle for the last 1000 miles. I don't know how it was driven for the previous 62,000 miles.) Do you guys have any thoughts as to what the problem could be?
