Ram tranny problems

When I switched valve bodies in my 03 Ram (46RE) trans the valve body had Sonnax sure cure kit in it. Would this be a good idea since he is going to be going into trans anyway Tracy?

I've never used one so I can't comment on it. I see it's a real expensive bugger. It should help a lot for that price, LOL
