Default Is my 4l60e going bad?

So yesterday I go to take off from a stop and it takes a lot more rpms than usual to get the car moving (~1500). Then after getting moving my convertor won't lock up. This is the third time this has happened in the last couple of weeks. What could be going wrong?

in my 93 it'd take until about 2k rpm to get moving on cold starts sometimes. kinda liked it because it was like a free high stall converter. transmission was fine for the month i owned the car. the guy i sold it to has had it for almost a year now with no problems.

never figured out what it was and no one i talked to had any idea either

Was everything cold when that happen? Did you buy the converter new or used?

It has only done it while it is hot. I bought the convertor new and have only put about 1500 miles on it.

I figure if something is going wrong it would do it everytime.

Scan for codes and look for PO757 if its there have it removed as a test in the tuning

As Frank said you are in limp mode. You probably actually took off in 2nd or even maybe 3rd thats why it seemed that way. If you just put a converter in thats the problem for sure. You are throwing either an PO757 or a PO751 code. For some reason its very random with converters on those codes, some people get them, some don't, some get them once and a while and some get them all the time. It happens to people all with different companies converters so its not dependent on that either. Have a tuner remove those two codes and you will be golden.

Thanks a lot for the help guys. I have HPTuners so I'll try removing that code and see if it works.
