Lucas or Trans-X ?

I know I've been asking tons of questions as a new Jeep owner but here is another.

Trans-X or Lucas for my transmission or neither?

It's difficult because there is so much contradicting information.

I know Daimler Chrysler doesn't recommend additives. I know I've read people's opinions about Lucas but most are from people who have used it on other vehicles or had friends that did, not a lot of info from people that used it on their Jeeps. I also read at least once someone mentioning that Trans-X is better for Chrysler vehicles than Lucas is.

Extended Reading:

Basically my transmission has become more noticeable when shifting, I changed the fluid and filter and I believe that helped but with almost 100K miles on that transmission and the fact that it was 9K miles past due for the fluid change I am thinking something like Lucas would be good to add but again I've read so much that I am looking for any additional info anyone can share.

Thanks in advance!

Brian,
I don't recommend any additives or fluids other than Mopar ATF+ 4 in your transmission. If you used any fluid other than ATF+ 4 when you changed the fluid and filter, that is probably the source of your current problem.
If you did use ATF+ 4 at the last filter/fluid change, then you may have a sticking selenoid. An air test performed at any reputable transmission specialty shop will quickly verify or disprove this idea.

Trans X Or Lucas?

Hey Guys, I'll Try To Help A Little Bit If I Can. I've Been An Auto Mechanic For 28 Years & The Way I've Done It Is If An Automatic Trans. Slips It's On Its Way Out. If You Want To Safe Guard A Good Non-Slipping Trans., Use Trans-X. I Am Not A Dealer Or Get Paid By These Guys What So Ever. The Dealer Will Still Warranty The Trans. If You Use It. What I Do Is Add Half The Bottle To Trans., Drive It For 200-300 Miles (This Gives It A Chance To Clean The Valve Body & Ports In The Trans.) Then Change The Fluid & Filter & Add The Other Half Bottle To Good Fluid In Tranny. This Will Continue To Clean & Help Your Transmission. I Have Done This With Every Vehicle I Own, I've Had My 2001 Buick LeSabre Limited From The Time It Was New & Now Has 192,000 Miles On it, I Added Trans X Right Away When I Bought It, Drove It For 200 Miles, Then Changed Fluid & Filter & Added The Other Half Of The Trans X Bottle, I Have Never Had One Bit Of Trouble With That Tranny, 1975 Chevy Full-Time 4X4, I Rebuilt Trans. Added Trans X, Now Has 20,000 Miles On It, No Problems With It. I Do Use Lucas Engine Oil Stabilizer In The Engines On All My Vehicles, Lawnmowers & Snowblower. I Have Heard You Can Add Lucas Engine Oil Stabilizer To Your Transfer Case & Front & Rear Drive Axle Gear Boxes Also. I Have Not Used Lucas Tranny Additive So I Do Not Know How It Works, I Have Had Great Success With Trans X So I Will Not Change. Good Luck Guys!

Why is every word capitalized at the beginning?

No additive in ZJ trannys. ATF+4 fluid only.

Engineers design and build transmissions and recommend what fluids they require.....additives are designed usually by non-engineers with the hope of selling to the non-engineer driver! If you are willing to second guess a group of well educated professionals be my guest.

If the tranny was slipping and you needed a rebuild is the only time I would use an additive to try and squeeze some more miles out of it.

chrysler transmissions are best if all that goes in is the correct fluid (or a backwards compatible chrysler spec fluid)

nearly every person i've known to have a chrysler transmission fail have used something else... either a universal fluid or an additive

(i say nearly because my sister killed her lebaron's transmission by driving it like it was a racecar and my mom had the transmission in her van blow a seal after a rather significant number of miles which included a fair bit of towing... and IIRC when my dad's ram charger took a manhole (was loose and his tire spun on it making it fly up) to the underside it damaged the transmission)
