'02 Lerado
Had the engine light come on steady and the dealer scan indicated something
to do with a"lock up"function of the transmission that is to enable a few
extra miles per gallon.They could not find any info about the code the scan
was giving them.They would clear the computer and after several weeks it
would come on again same code.After going back 5 times I finally got a file
number and told them to fix it or I would invoke the lemon law.
They took the Jeep and pulled the Trans and said a seal was leaking
and repaired it.That was 4 wks ago and the light has not come back on.I want
to know if it is possible to disable the"lockup" function so the scan would
not pick it up?I'm not sure at this time if a drop in mpg has occurred.Thank
you.

Why do you think they would do that nasty trick to disable the torque
converter lockup? It would only come back to haunt them. Since they
removed the tranny it is very likely that they corrected the problem.
A functioning lockup TC is very easy to see on a test drive - the
engine rpm will drop as you back off on the throttle. It's a more
subtle jolt than the normal shift. With a 4 speed auto it acts as if
you have several extra gears. If I recall correctly, in the XJ tranny
the TC will lock in the three highest gears.
There is a computer that controls the shifting and lockup, located
underneath the glovebox. That should have been checked early on during
the troubleshooting.

Re: '02 Lerado
The first thing they tried was replacing the TC.That did not solve the
problem.Replacing the computer was the second thing they did and pulling the
TM and repairing the leaking seal was last month..I must admit this is the
most comfortable I've been with a service department in fifty years of
buying cars.My friend has a older car and the 'lockup"would not release and
his buddy at the shop told him to pull the plug so it would release and
drive until it failed completely because of the vehicles age.

Re: '02 Lerado
Unplugging the TCC (torgque converter clutch) or otherwise disabling it
won't get past the onboard computer, and the light will come back on if that
is what was done. I don't think that the dealer would have done that.
Further, it is unwise to disconnect or otherwise disable the TCC. A torque
converter that does not lock up produces an enormous amount of heat, which
will ruin the transmission. Your buddy that did that didn't gain anything
except a broken transmission from the inevitable failure due to overheating.

Re: '02 Lerado
Unplugging the TCC (torgque converter clutch) or otherwise disabling it
won't get past the onboard computer, and the light will come back on if that
is what was done. I don't think that the dealer would have done that.
Further, it is unwise to disconnect or otherwise disable the TCC. A torque
converter that does not lock up produces an enormous amount of heat, which
will ruin the transmission. Your buddy that did that didn't gain anything
except a broken transmission from the inevitable failure due to overheating.
