Well a flush doesn't get rid of all the old fluid. It just keeps cycling new fluid in for bad and never leaves the pan. It also basically just dilutes the old fluid in with the new. Also, when they do a flush at places like Valvoline or Jiffy Lube, they don't drop the pan and replace the filters.

A dirty filter is just as bad as a dirty fluid.

Would you want all your contaminated fluid going thru the system over and over again? Didn't think so, this is why purging all the fluid out is a better way. It's also cheaper to do and you don't need big pieces of machinery sucking the life out of your transmission.

Also i hear they back flush everything so what all was getting caught in the filters is just pushed back through all your lines and such. thats why people say not to get a tranny flush.


I plan on doing it all myself. Just drop the pan, replace filters and replace fluid in the pan.

It might be a bit of a drive in your case...it was kind of more along the lines of if your in the neighborhood type of thing. Either way they still get my vote as far as dealers go.

Most dealer prices on the items that you need such as filters and RTV should be fairly comparable so not a big loss. Again somethings I will say suck it up and go with dealer on. REMEMBER USE THE MOPAR BLACK RTV FOR SEALANT ON THE PAN..NO GASKET.

Alright, yeah so widow they do back flush everything? that seems kind of dumb if all the amateurs, do-it-yourself'ers and hydra know its not good than you'd think the professionals would know it too?

Yeah, i hear ya magic. That "black mopar rtv sealant" is that something i can buy at autozone or should i go get it from the dealer?

+1000 on the flush being a bad thing. Just drop the pan, change the filter(s), and put the pan back on. Add the fluid through the dipstick tube by using a small funnel. Make sure you can get to all of the bolts on the pan before you start taking them out. Depending on the year / model, you may have a clearance issue by the tranny crossmember mount to contend with.

PM me if you need step by step instructions, but it's really an easy job, not much worse than a normal oil change. I did mine on Saturday and it look less than an hour. FWIW, Dodge dealers seem to charge a LOT of money for the filters (mine were $52 total) but I've never tried anybody elses.

Forgot to add that Mopar sealant is (IMHO) nothing different than other good silicone ones. Any high quality sealant should work fine. (Permatex, Form-a-Gasket, etc.)

While the pan is off check it closely for excessive rust / damage. That's why I ended up replacing mine last weekend.
