My check engine light came on and I checked it out and got PO740 code. Which is TCC circuit malfuntion. Does this mean that the transmission has to be rebulit?

No it doesn’t necessarily means that the trans needs to be rebuilt. The TCC is the “torque converter clutch.” Its engagement is probably controlled by a solenoid and the circuit for that solenoid or the solenoid itself has a problem.

You’ll likely need a good trans shop to look at it to isolate the problem and deal with it. “Good” trans shop should be an independent local trans specialist - not a national chain shop.

There is a good chance that the problem is minor. I cleared up a similar problem once on a Ford Escort just by doing a pan/filter service a couple of times in quick succession.

So if your trans is due for service (pan/filter every 30K) maybe you should do it and see what happens. If you don’t do things like that yourself - take it to a trans shop, ask them to check it out & service it.

I have to agree, the tranny may not need a rebuild. Most TCC solenoids are servicable, and inside the tranny pan. Change the fluid and filter at the same time. Remember that a tranny shop is there to sell you a tranny. A good mechanic will test for the cause of the code.
