everyone knows dodge has been lacking in the automatic trans department for some time. long story short, i am on my 4th trans overall and 3rd ats built trans. the 5 year warranty which has been great, is about to expire and im looking at other options but dont know an extensive amount about transmissions. im debating on swapping in a 4l80e because the truck is built up, and runs 37"s and is a daily/ shop truck/ pre runner. ive found adapter kits, now im wondering what options for shifting there are. would like a gated shifter but would also like the t/c lock up to be automatic for the daily driven and hiway driving aspect. any input into my query would be appreciated.

47 and 48 r.e. trans can be built to handle quite a bit of power. They hold up to some pretty stout diesel engines. Maintenance and band adjustments will allow these transmissions to live long happy lives. Using these transmissions in a performance application is less common because it's not g.m.
The adapters to put a 4l80 in will set you back about the cost of the required parts to build up a 47 or 48 r.e.
Then you still need a transmission control and shifter for the 4l80.
