Transmission problem on my 2000 Pontiac
Montana. Where is the TCC Solenoid located on
a 2000 Pontiac Montana?
The TCC control solenoid is located in the valve
body. The side cover of the transmission will
need to come off to access it.
In order to remove the side cover, the engine /
frame / trans will have to be lowered from the van
on the drivers side while the whole assembly is
supported from above so as not to fall out of the
van. This is quite a big job to replace.
2003 Pontiac Grand Prix Check Engine Light
Question = I have a 2003 Pontiac Grand Prix with
84,000 miles on it. My "Service Engine Soon" light
just came on about a month ago and when it did
my cruise control stopped working as well. I can
feel it has trouble shifting and I have hooked it up
to a machine that AutoZone has to check my
problem and it says its a transmission module
We have asked others who say that it probably isn't
the problem because they have never heard of one
of those going out and it's probably a wiring
issue. Can you tell me what you think it might be?
This codes refers to the 1-2 shift solenoid. Be sure
to check all fuses first. Specifically the "TCC" fuse
in the underhood fuse block.
If that is ok, 2 things possible. Either you have a
connector problem at the 20-way transmission case
connector causing this code, or the solenoid. The
solenoid is on the valve body in the side case of the
Suggest disconnecting transmission connector with
key off, look at all terminal, pull the harness a little
so as to change its position, then plug it back in.
Clear the codes and drive it.
