Am trying to find out also how many Solenoids are in the transmission and how to replace them.. thank you KEITH
There are 3 shift solenoids replacing will require removing pan first you need to find out the one that's bad
SOURCE: Hello, I own a 93
The transmission is controlled by the Transmission Control Unit (TCU).
Throttle
position, rpm, and speed are input parameters to the TCU. The TCU has a
default set of shift patterns. These shift patterns change over time
based on your specific vehicle setup and driving habbits.
The
shift patterns are only slightly affected by driving habbits over many
driving cycles. But, changing the relationship between the throttle
position and the actual speed being reported by the speed sensor can
have an immediate effect on shift patterns.
While your speedo
may now be correct, the realtionship between rpm and thottle position
has not been corrected. That would take a gear change in the
differentials.
The TCU can be reset to an inital learn base line. When this is done, the TCU will instantly learn the dynamics of your setup.
Any shop with an advanced ODB scan tool can reset the the TCU. The dealer or a transmission shop would be preferable.
You really should change your differential gears as opposed to resetting the TCU

low fuel pressure because of pump or fuel filter problem can cause motor to run lean - filter should be on right side under back door by suspension arm - pump is in gas tank

Just ask for the 3,4 shift solenoid, in which case the transmission pan has to be taken off, the filter, and possibly the valve body to get at the solenoid, I don't have my manual right now, so I can't tell you which solenoid it is.
The speed sensor is usually screwed into the side of the tranny near the back end of it, don't confuse it with the back up light switch, that's screwed in somewhere in the center of the tranny. Hope this helped a little. Good Luck.

I just did this today just lower the subframe it was plenty of room and didn't have to take it out
SOURCE: need to replace the thermostat on my 2002 buick la
The thermostat is normally located in the aluminium elbow that the top radiator hose connects to. The elbow is usually held down by two bolts and it is only necessary to remove these to replace the thermostat. It may not be necessary to remove any hoses. Take care that the new thermostat is correctly located in its recess and the old gasketing has been completely removed and that the new gasket has a smear of gasket cement on it. While tightening the bolts, make sure that the elbow is seating evenly and not catching on the edge of the thermostat or you could crack the elbow.
