Wj Transmission Fluid Change

Recently purchased a 03 Overland with 86K and im currently in the process of changing out all the fluid. Already did an oil change, TC fluid change, and rear diff myself (doing the front diff this weekend). I want to bring it in to my local transmission shop to have the fluid drained/re-filled. They are running a special for $49.95 including the filters. Im pretty sure they don't use the Mopar filters and was wondering if what they use would be sufficient. I did ask if I could supply the filter, to which they said i could but it wouldn't affect the price. Should i just go with what they use?

50 bucks? The dealer quoted me 400. 50 seems really cheap

if you can change your own oil, you can change your own trans fluid. thats not a bad price though. i spent about $60 on ATF, filters (there is two of them), and some rtv. i got my filters from NAPA and havent had any problems. There was a bad batch of filters a while back but most of them are off the shelves by now.

$400 to change your tranny fluid!? I would stay away from the dealership. Like Dave said if you can change your oil, you can change the tranny fluid. It really isn't that complicated you just need to have the proper tools to do it, i.e torque wrench. I have a cheap one from H.F, but its a 1/2in drive and doesn't go down to in/lbs. My next change i will probably try to do it myself, just dont have the time right now.

for the 4.7, i dont know if its teh smae in teh 4.0

the main down side i see to doing transmission service on a WJ is filling it up it up since the tube a bit odd and small so its slow. also since the tube is small siphoning it is a bit slow but not as messy. still will get oil in the pan but not as much that will splatter eveywere

Talked to them again today. It will cost $60 to replace the fluid and both filters. I asked them if they could use ATF +4 instead of the additive that they use and the mechanic told me that ATF +4 is crap compared to the additive. He said that they use the additive when they rebuild trans. What do you think, should i take there word or insist that they use ATF +4?

Please those with knowledge/experience with tranny's clarify this for me.

No, dont let them do that. ATF+4 is tightly regulated and the Chrysler transmissions are not very forgiving. The ONLY exception to my experience with the additive is when I had some pretty nasty slipping issues with my AW4 (Not a chrysler transmission) in my XJ the Lucas stabilizer fixed it until I had time to drain and refill. Than I drained and refilled with the stuff it wanted (dex/merc) and it has run great since then, no additive at all. That stuff is thick as molasses and I wouldnt want to run it as primary fluid. If theres nothing wrong with the transmission why risk running something different and causing a problem? Exactly

ATF+4 or bust. Its $7 a quart for the Valvoline ATF+4 and I consider that good stuff. Technically the stuff is so tightly regulated even house brand autozone crap will do just fine but I still pay the extra bucks for the Valvoline

well im sure the mechanics engineering degree led him to beliefs that atf+4 is crap compared to his additive. Tell him to beat it and do it urself

i dont get why all these shops dont understand Chrysler transmission need atf+4 or needed atf+3.

i went to 3 transmission shops around me and they all told me they dont use atf fluid just.


do it yourself or bring the right fluid and filters then watch him do it or take it to a dealer.

only atf+4 i find is Valvolineand its $6 at autozone.
they have a house brand atf+3 for $5
