I'm about to buy a 92 nissan stanza with automatic from a friend who had to
put another tranny in the car. He just put a transmission from the junkyard
in it, and it does fine except it seems to be starting off in second gear.
After it gets going it does fine. I think he even said that it'll kick
down to first once you get it up to speed and stomp down on the gas. I
searched on some parts sites and saw that there are a few parts that I
think could be causing this. My friend has been told that it is the speed
sensor causing this but I also saw some kind of torque converter sylenoid
and was wondering if that may be what is wrong. I don't know that much
about transmissions so any help would be greatly appreciated. Thanks
