My question is this, What does a torque converter do or sound like when it is bad? Especially does it make a noise or grinding noise.
I have a 1986 chevy K10 4x4 (305ci, 700R4 trans., NP208 transfer case) for more info check post a few down that has a title of "Elusive grinding noise". Thanks in advance for all the help you guys have tried to help but i still cant pin point the noise.
Depends on what (if anything) is wrong with it. Some failure/failing modes may be noisy, others can be silent. The noisy ones might sound like grinding or scraping, or any of a number of other sounds.
In other words, it's going to be tough deciding what the problem is, and even tougher when you can't be *SURE* that it is indeed the TC making the noise. There's a whole bunch of things on a car (or truck) that have the potential to make grinding noises, and until you can pinpoint which of them is the source, you're just chasing your own tail.
