I have a 1997 pontiac grand prix with a 3.8 liter v6 engine, and my trans
occasionnally seems not to want to shift from 3rd to 4th it eventually
shifts but its later than it use to shift. I was thinking that it may be
the shift solenoid,if so can it be replaced by just removing the trans pan
or do the trans need to be removed from the car . Also is it just one
solenoid or are there several. If the trans do not have to be removed do
i just drop the pan and replace the solenoid. thanks for your help.
