I took my truck out for a ride today and when it shifted from 1st to 2nd there was a big clunk. After that it was stuck in third gear. I could manually get it into 1st, 2nd or 3rd but when in drive it was stuck in 3rd. I shut the truck off/on and all is OK now. Any ideas what it could have been?
Thanks,
Joe

sounds like what happened to me
it's just a module that communicates to the trannie; it's located behind the ignition, a quick fix

Some customers may comment on one or more of the following conditions:</P>

<LI>The Malfunction Indicator Lamp (MIL) is ON.
<LI>The transmission is stuck in third gear.
<LI>The instrument cluster is inoperative. </LI>[/list]

<H5>Cause</A></H5>
The most likely cause of this condition may be a loss of power to the
transmission on circuit1020. This loss of power may be caused by an open
in the ignition switch. This condition may also be the result of an incorrect
installation of an aftermarket electronic device such as a remote starter or
alarm system.</P><A name=ss3-1371241><A

If battery voltage is present at the fuse, inspect circuit1020 between
the fuse and the transmission for possible opens. If battery voltage is not
present at the fuse, replace the ignition switch using the Ignition Switch
Replacement procedure in the Steering Wheel and Column sub-section of the
applicable Service Manual. Refer to group number 2.188 of the parts catalog for
part description and usage.</P>
If the vehicle is equipped with an aftermarket electronic device and the DTCs
are being set when the device is being used, verify that the appropriate fuse
listed above is being supplied battery voltage during operation. If voltage is
not present at this fuse, these DTCs will be set due to lack of power at the
solenoids. This condition is most likely to occur with an incorrectly installed
remote starting system. If this is the case, refer the customer to the installer
of the system for corrections.</P><A name=ss4-1371241><A

I saw that on 20/20, all of these quick lube places secretly get rid of their oil by spraying customer's air filters with the used oil. They don't have to pay as much for the disposal fees. This is one reason why pollution levels have risen drastically.
