So I want to add a shift kit, I heard I should get it flashed to a 545FRE first but now I see they make a 6 gear programming for the 545FRE, question is could mine handle 6 gears??? Also how do I go about adding a shift kit I know there purpose but how do I add one. Thanks

The 6 "gears" are already in there. The 545RFE flash enables a second overdrive ratio, (aka 6th gear), while the 45RFE uses only one overdrive, (5th gear).

As for the shift kit, here's a write up on how to install it, as well as change the fluid, which you might as well do when you open it all up.

So would the dealership flash it to a 6 speed, if so how much?

Yes, dealership would do it, but I have no idea how much they would charge you. Are you sure no one has done it on your Jeep as of yet?

yours already is.

Only the 99-mid 2001 ones didn't have the 6 speed software.

There are 6 forward gears, with two 2nd gears. One for the upshift, one for the downshift when you get on it.

Oh, I thought it was two different ratios and the computer chooses the one depending on what you're asking it to do (upshift/downshift). Didn't know it was actually two different gears.

Hmm, this is new news to me. I did know my WJ had 6 speeds, so the dealer can flash this and your good to go? Does this help drivablity?

if you're at 2000 rpm while going 70, you already have the flash. Both second gears come from the factory on all models, 99-mid 2001 didn't have the "second overdrive" which the software flash takes care of.

Personally, living in a hilly area, I wish I didn't have the second over drive (5th gear), especially after bigger tires. I down shift way too much at highway speeds (55+, hitting mountains)

Those two things are the same thing.
