Can I have an upside down linkage in my durango?

Recently my husbands friend replaced a band strut in my 2002 dodge durango (46re). Ever since he replaced it, it has a problem from getting from 0-20. Then after about 20 mph it's fine. From a dead stop it can barely accelerate. However I tried to drive it in 2nd, then first and it drove normally. Could he have put it back in upside down?
