#34 of 48 torque converter problem for 2008 Matrix by hunkymon

I have a 2008 Toyota Matrix. The check engine light came on and the scope came back with torque converter problem. Does anyone know what this involves and how it would affect the transmission? Thanx

The 2007 wagon DOES have a tire monitor. I just checked my tires when it went on the other day. You not only have to check your tire pressure but also your spare.

On the Matrix the Maintenance light is a signal to have the car serviced - i.e. reminder to have the oil changed and the light reset. No major problems are indicated. The check engine light is another matter.

My 2003 Toyota Matrix constantly has a check engine light. I change oil every 3,000 and service regularly. My gas cap is not loose. The codes say it is the catalytic converter, but I have changed the part twice, (not Toyota part) and it made no difference. Our 2001 Tacoma also has the exact same problem. We are getting exasperated with this issue. The vehicles run fine and fuel consumption is average. Both vehicles have almost 200,000 miles. Any thoughts???

Often times aftermarket cat converters do not work well enough to satisfy the cars self test routine.
 
More importantly those engine codes never say directly that a particular part is bad.
They only mean that there's a problem in that part of the system.
You (or a knowledgeable tech) need to look at the signals coming from the O2 sensors with a scanner or oscilloscope to figure out what's really going on.

My 2008 Matrix check engine light was on. On the scanner it came up as torque converter. Had the transmission rebuilt. 200 miles later light came on again. Had it rebuilt second time under warranty. Light still comes on periodically, but turns off after couple hundred miles. Haven't had it checked since the last rebuild, but I'm afraid it will come up as torque converter. It's off warranty now so I'm just buying time.

What was the code number? It will look like P0123.
The torque converter isn't inside the transmission, so rebuilding the trans doesn't make sense.
Anyway that didn't solve your problem. Like I said, an error code does not point to a particular problem.
I would take it to a independent transmission shop (NOT AAMCO or Cottman!). Maybe they will be competent.

Thanks cirsuitsmith. I'll have it checked when it comes on again.

My last post should have said at the end:
 
Like I said, an error code does not point to a particular part.
