Default 96 Accord, Tranny problems, P0740 TCC Circuit malfunction

My girlfriend has a 96 Accord LX 4 spd. AUTOMATIC. For some reason the check engine light keeps coming on about every 2-3 days. It keeps throwing the same code, P0740, TCC (Tourque Converter Clutch) circiut malfunction. I know what a torque converter is and what it does, but I don't understand what all this means. Does any one know what's going on? Btw, the ATF is at the proper level. Thanks!

You need a transmission. I see that code everyday at work Acc/ody transmissions are awful.

uh.. yeah thats why they last longer than any other transmission out there, and why cars get sold for over 2.5k everyday with more than 200k miles on them. Your right, they are awful.

and for the OP, it sounds like a problem with just the torque converter, and its probably something electric. You could take it into a tranny shop have them look at it.. you'll probably need to replace the converter, and your tranny is fine.

OK, so do I need a new tranny or no? Just to give you guys some history, the car was purchased used with 96K miles on it. It now has about 127K miles on it. When I first changed the transmission fluid it was damn near black and smelt AWFUL!!! Plus, the magnetic tranny drain plug had ALOT of metal shavings on it. I think this car was probably abused and neglected.

Hmmm, right. I work for a Honda dealer. If Honda has no clue about the Acc/Ody trans issues, why did they extend the warranty to 7yrs or 100k on. As a matter of fact a customer has a Ody in the shop right now getting his SECOND warranty tranny.

But, take it to a tranny shop.

on the 96 trannys, i've heard of little to no problems. The 6th gen autos suck yeah, but this isn't a 6 gen there now is it?
