i have the 4.0 inline 6, 4 wheel drive, automatic tranny

 

Does it make any kind of noise when it "slips"?

Mine makes a clunk as it "slips" in a similar scenario as yours, and I think the slip yolk on my rear driveshaft is sticking.

 

well i went on a hill in reverse i had it in 2 wheel drive and it pulled by it self and i didint feel any problems, i gave it gas and it pulled just fine it did not feel like its slipping. So i think its all good iima just change the tranny fluid as its getting orangish/brownish. Thanks everyone for the responses.

All i got now is a clunking/thump sound from the front right. I think it could be an engine mount might need to tighten the bolts, or maybe a bushing any ideas? Its only when i go through bumps you here a soft thump.

 

Yes that is how Xj idle i was worried about it too when i got mine. but yeah after looking it up and asking around that is how they idle

 

Lucas is good....drain the pan, change the filter, and see what happens. Put some lucas in it...Not a permanent fix, but will help. And remember boys and girls...the AW4, is used by toyota....different bell housing...(learned that from the tranny shop, where my best bud works)...

 

over this long weekend i drove it to michigan 350 miles and the tranny was fine, maybe im just looking for problems when they dont exist lol. Could be also that im not use to the jeep. But to be honest i think its all good.

Thanks again everyone. Yes i will change the filter out as well if i do a tranny flush.

 

Lucas is the absolute worse thing you can put in your transmission. It is designed to swell seals. Well, guess what? Transmissions have internal seals that arent designed to expand to seal a component, they CONTRACT.

pour lucas in your trans and go ahead and schedule a rebuild.

Not very many transmissions have more than one band, and a band will only control one, maybe two gears. If someone tells you the "bands are slipping" they have no idea what they are talking about.

There are many different clutch packs that provide your forward/reverse movement. Check your fluid level first. If its low, burnt, and smells nasty chances are youve already done damage. It sounds like your trans might be low on fluid. Be sure to check it in nuetral for a true reading, chryslers read between a half to a full quart higher than they should in park.

When you come to a quick stop, then try and take off again, the fluid is sloshing around in the pan. If your fluid level is low, you can experience a "hiccup" where the pump just isnt getting fluid for a second.

 

Lucas works on engines, NOT transmissions. Its a gimmick.

Btw, if the fluid hasnt been changed regularly for the entire life of the truck, just service the trans. Change the filter and refill. Dont try and flush all the old fluid out at once. Plus it gives you a chance to examine the pan for signs of damage.

A flush is exactly that, it flushes money out of your wallet and into the shops.

 

so what should i do ? Just change the filter ? i still got to drain it to refill dont i ? My bro works at a shop so he can do the tranny flush for free, i just need to buy the fluid.

And you said not to flush it out all at once so just drain some of it out and put some new in ? then later on do it again until the new fluid takes over and the old one is all drained out ?

 

when you drop the pan to change the filter you will lose around 5 quarts. Just refill with new fluid. Total capacity is around 12 quarts

 

All I can tell you is the car would not move; I put Lucas Trans Fix in it. It moved. It’s still moving! I can’t tell you what swelled or what didn’t swell. I watched a man pull apart a transmission; he held several thin rings in his hand. They looked like huge lock washers but they were flat. He called them bands. Okay then, to me and probably hundreds of other people that I have met over the last thirty plus years of driving and who have talked to me about transmissions, they are bands. I can see them all acting as individual clutch rings but I have always heard of them being called bands.

 

There is only one clutch band in an aw4. Its for engine braking in 2nd.

If they were wide rings that came out with the clutches from a drum, the correct terminology is "steels". You would have a bunch of those, theres anywhere between 3-8 in each clutch pack.

As far as the lucas, you got lucky. Its bad news for transmissions. Ive R&R'd for three different builders, all with 20+ years of experience. All 5 years of my experience are at a nationally known transmission shop. The only, and i mean ONLY additive we have ever used is a product called lubeguard. Its a friction modifier that is added to our regular dex/merc fluid to make it compatible with different brands. Certain brands get certain bottles.

There is no "fix in a bottle" for anything. Not engines, not transmissions, not fuel injectors, not anything on a vehicle. They are bandaids that cover up problems. If theres a problem, fix it the right way. Its not /that/ much harder and will save you money in the long run.

 

You are right! There is not a fix in a bottle; but, if I can put something in that will prolong the inevitable rebuild or replacement and it will cost less than $20.00. I’ll use it. The way I look at it, if I can get a few more thousand miles out of a trans, that I know will need to be rebuilt or replaced, I’m going for it! I like my money staying in my pocket for as long as possible.

Well huntsman, the decision is up to you. You have two opinions here. One from a consumer and one from a paid R&D spokesman who works for a national chain!

 

I use ATF+4 that's the manufacture recommended transmission fluid for the AW4 transmission. I hear a lot of people use dex/merc but I don't know why. Take your transmission to a shop and have them look at it. That will save you a lot of time and money. I had a bad tranny that I thought was good for like 6 months the tranny was burnt bad but I poured like 400 dollars in soleniodes,fluids, other electrical junk... When really my tranny was officially burnt and bad... Thats just my 2 cents

 

Well i actually think my tranny is good i just gotta put new fluid in and il be good to go.I dont believe its slipping. Time to buy some more of the valvoline maxlife and filter, ima try to drop the pan this weekend and replace the filter and the fluid the pours out. I was just curious to what the symptoms are of a slipping tranny.
