<<Hi, I just test drove a 1995 GMC Suburban and the owner told me that
on some occasions, the car wouldn't shift from second to third gear. He
then had to put the car in neutral, switch off the contact, switch it
back on and it would then shift from second to third gear. This would
only happen once while driving it and then the problem would not occur
anymore. Sometimes this wouldn't occur for weeks or months. Can this be
a problem? What would be the problem and how can it be fixed? Thanks,
Of course this is a problem, although it seems to be intermittent -- at
least for the time being. From what you have said, when the transmission
fails to shift from second to third gear, you must stop the vehicle and
then go through a work-around procedure which, so far, has restored the
transmission back to a normal shifting pattern.
When the transmission is in the "2" position, it starts out in second
gear and stays in second gear. Perhaps the selector is defective and is
locking the transmission into this setting.
I am assuming that you are having the shift problem when the
transmission is in the "D" position. If the transmission shifts properly
after fiddling around with the gear selector, then the gear selector is
likely the source of the problem.
Take the vehicle to a transmission specialist and see what he
