Transmissions and questions about em…..

Ok guys.....a few questions....

If the 518 Transmission is a 727 with a lockup torque converter and an overdrive unit, how come it seems to have so many problems? Wouldn't it be just as good to put an overdrive unit on the BACK of a 727 and eliminate the problems?

I've heard that folks are swapping their 727's for 518's and was wondering if they were experiencing the same problems that the stock units seem to have.

Maybe I should post this on the truck site......Hmmmm
