are 47re autos weak?

My truck is bone stock. No power adders, nothing. IMO it’s not a great trans in stock form. Maybe a few thousand in billet parts from Goerend Trans will do the trick if I rebuild it, but autos are a lame duck transmission anyway.
It really needs a manual.
All I can tell you is I’ve had a 95 with a 46RE, a 2003&2004 with a 47RE, a 2007 with a 48RE and a 2018 and 2020 now with a 68RE. I’ve never had trans trouble with any of them. Thou I’m anal about service.
