To be honest, I think it's just because of marketing! The competition offers
it so we have to too. Sort of like 4 wheel disc brakes on the '87 Shelby Z.
The stock rear discs aren't that good and they stop fine with rear drums but
they had them on the RWD and heavier Camaro so Dodge added them. If the top
gear ratio would have been higher then fuel mileage would have improved or
with a quicker 1st gear ( the 45RFE already had a pretty good one. It's
about the same ratio as an A-555 manual trans!) then acceleration
performance would have increased but it apparently wasn't worth the extra
cost. Since it was just a programming change, they could do that cheap
enough though.

Sounds like they had that in mind from the drawing broad. If there no
"really isn't any performance gain or any mileage gain either since the top
gear ratio is still the same", Then what's the advantage to the "5th"
 

Thank you and have a safe day.

The 545RFE is a 45RFE! It just has a different computer to make it have 5
speeds! You can have the program flashed in and make you're 45RFE a 5 speed.
It has already been set up that way from that way from the factory in the
Grand Cherokee for about a year now. There really isn't any performance gain
or any mileage gain either since the top gear ratio is still the same.

John,
 
I heard that in 2003 the Dakota will have a 5 speed version of the 45RFE
called the 545RFE. Is this true? And would this new 545RFE be swappable with
the 45RFE?
 
Thanks
