02libby 3.7l 112k should I do a trans flush or drain and fill? Just bought jeep lib and was wondered the best approach. Is there any vendors here w/ special pricing/shipping? On the diesel website I go to, they have some specials better than the dealership I work at. Please give me a call 912-659-3406 -Chase

I don't know why so many people are against getting a flush, but it seems to be the best option to me.
If you make sure they leave the filters on while doing the flush then no gunk or metal should get thru. After the flush is complete then they can remove the filters and replace them. Why not get a flush if it's done this way? Replaces all of the fluid so you have a nice, new, fresh fluid flowing thru the whole system, and you can be confident that it will be good for a long, long time.

Some people say that certain flushes actually go reverse of the normal flow.. Thats why they are bad.. Im not sure which way they really go though..

I always drop the pan..

The tranny flush machine is actually just a fluid exchanger.Our machine hooks up to the top line and top radiator input.
Onced hooked up,we add 1 pint of flush and idle engine for about 20 minutes or so. Turn off engine and program the machine to empty pan,remove pan and replace filter.Then program machine to cycle total fill amount plus conditioner,while removing the equal amount of used fluid.On our machine if you hook the flow up in the wrong direction,it will beep telling you to reverse the lines via quick connectors.The tranny actually does all of the pumping,not the machine,so you just have to make sure you have the flow lines hooked up correctly.It is the best of both worlds in that you get a new filter and complete fluid change.Because of the extra fluid it cost more,but it's worth it.

Ron, you obviously really know your stuff, and have lots of experience doing it. I know the opinions vary, but in your opinion, how often should the flush/filter service be done?(My kj is a manual, but I do have a 2006 chrysler town and country van, and their tranny's do not have the best rep.)
Thanks!

In all honesty hooperswish.....I'm not a real big fan of tranny services....I mean my luck was that the more i done a service to one of my cars,it seemed like shortly after I would start having tranny problems.Tranny fluid is highly detergent,and I feel that with a transmission that is poorly built or has been neglected,it tends to wash away the clutch material sooner.As TJKJ2002 once said "I'm not a big fan of anything Lifetime"but with the tranny,I sometimes wonder if your better off to just leave it alone.I don't mean to confuse you,just sharing my experiences.My 97 Dakota has a little over 100,000 on it and cause I drive it cautiously,the fluid still looks bright red and smells comparitable to new.But then again.....It could go out tommorow. :roll:

To sum it all up.....I would use the schedule under normal driving conditions,but go all the way with a complete exchange and new filter,and you should be alright.Again,these are just my opinions,and I don't want to butt heads with anyone. :wink:

is it okay to use the mercon with the additive? I only had the mercon avail. and I was told that the mech. shop only used one type of trans fluid. but used the trans. additive.

I would use ATF+4 because it not only has friction modifiers,it is also a synthetic base.And even better than that,you could PM JJ'sKJ and check into an "Amsoil" program.
And again....Do a complete flush.It does cost alot,but you'll sleep better knowing you just protected one of the most costly components of your jeep.
