Just purchase brand name fluids and you will be fine. ALL Cherokee automatic transmissions use Dexron/Mercon transmission fluid. If your read differential has a Limited SLip you will need to add some Friction Modifier to the gear oil.

I use Valvoline high mileage tranny fluid and standard 75w-90w in the diffs. My tranny was shifting a little hard for my liking when I got it and drained it and put in the Valvaline high mileage and it shifts smoother now. I think the main thing is use the right fluids and good quality fluids.

Use a good "synthetic" for the diff's (not trying to start a war) along with a little Lucas.....http://www.lucasoil.com/products/dis...tid=2&loc=show

My rear differential would sometimes clunk into gear and now with the synthetic and lucas the noise is gone.....

I thought you were suppose to put ATF 4+ in the automatic transmissions it is formulated for Chrysler vehicles and transmissions.

well that is what I hear from Jeep. But I also hear they put some sort of additive in there as well. I just don't know exactly what.

Along with a couple of other problems I had, I used Lucas in my old T-case... oddly enough at the same time, My case exploded sending something (still don't know what) through the top of the case and forcing me to tow home after 226 miles and being 6 away from home... Bad day

Someone else already said to use brand name fluids, which is good advice. Having your own brand name tranny fluid put in will cost you if you can find a place to do it (assuming you're up for replacing all of your tranny fluid at once and not just doing the drain and fill method). For the tranny, just take it to a decent quick lube or shop you trust and make sure they don't use some black barrel tranny fluid. Make sure is Dextron/Mercon III! Lucas fluids are fine (gear lube, tranny, oil, whatever), but their additives just cover up problems.

If you referign tousing Lucas as a gear oil its great. Or adding it to another gear oil its utilized as a stabilizer.

Not sure what exactly you are refering to?

Their synthetic motor oils, gear oils, and other fluids are top notch stuff.


Their "oil stabilizer" or "transmission stop-slip" literally are an ultra high viscosity motor oil with a gasket softening compound to slow leaks and cover up issues and an ultra high viscosity transmission fluid. Nothing else. They cover up issues effectively, which makes them popular. If you have one of those motors of transmissions that needs heavier, higher viscosity fluids to hold it together, then they're great. Lucas' engine oil stabilizer inside of your gearboxes is WAAAY too high viscosity to use. If your gears are whining it'll probably shut them up, but the stuff is like molasses. I'd never use that stuff straight up as gear oil. It takes a solid 45 seconds to one minute to pour out a quart bottle.

Yeah, I use a 25-50% mix which has served me well so far.....I am not the type to cover up issues.....(you can refer to some diesel site that I am part of to verify that lol)

I only use it in my diff as a stabilizer not a magic cure all.....I am in agreement with you though....
