I've got a 2000 Escalade (GMT400), with a 4L60E that's starting to make some whining/howling, so I'm fearing the worst. At some point I'd like to swap an LQ4 into this truck, but I want to be sure that if I have this 4L60E rebuilt, that I'll still be able to use it with the LQ4. I'd hate to pay to have it redone just to have it be useless to me at swap time.

Thanks!
