I have a 1995 nissan pickup with a manual transmission, and i am having trouble shifting into first or second gear when i have come to a stop. If i turn off the A/C it will shift okay, it will also downshift into first or second with no proplem. I am worndering if the A/C
takes the revs up just enough to make it diffucult to shift????? If so how would i go about fixing the problem?

Any help would be great.

Thanks
Tom
