It's kinda like not wiping your butt today cause you're gonna take a crap tomorrow anyways..........

 

Gotta agree with Trev1006. If switching to synthetic or doing a flush gives you leaks, that means you have built up sludge AND bad seals. I can't imagine why someone would want to keep running like that. Specifically regarding synthetic engine oil, unless you switch to fluid you've kept in the garage from 30 years ago, that shouldn't happen. Or you were running detergentless oil in the first place which is another problem with all the gunk built up. Saying that there's an inherent risk in trying to fix something that was ever cared for is no excuse to continue ignoring it.

lmao cruiser

 

I switched to synthetic trans fluid at 154,000 miles. No problems. Some of these old wives tales seem to never die.

 

Hahahahahahaha!!!!

 

Seafoam trans tune is an awesome product for these aw4's in my opinion too.

 

If you're calling cruiser54 a random douche, he is one of the most knowledgeable members on here.......

 

im impressed..no really i am..let me switch my opinion on here

random internet douche and his buddy that says its ok to swap out transmission oil whenever > my trans guy that rebuilds and services transmission 60 hours a week and knows them inside and out, and builds anything and everything in this area that goes fast.

ok, where all set here.

 

These


Says the guy with 290 posts...
I hope you do something stupid and get banned.


And quit ****ing up another users thread.

 

I would say were all set here too, all set without his and your lame opinions.

 

your right, my knowledge on jeeps isn't as great therefore i only have 290 posts.

 

Does Wix make a trans filter for a 98?

@ 172,000 and believe it's overdue for a trans flush/change.

 

Should be wix p/n 58936, bout 30 bucks. I use hi mileage dex fluid from valvoline, never had a problem.

 

You guys a simple fluid and filter change ( this is what the op did) isn't even close to a flush job at any garage. You really need to get your fact straight on this stuff before you spit out an answer.

 

and i never stated a full flush job. my trans guy said he wouldn't recommend doing any fluid swap on it with that many miles. if you guys feel the need to test these myths, rock on. i was unawared that the op didn't know how to purchase the correct oil filter and it would be a easy fix. but i'm done with this thread either way. you guys have fun raising your post count. i'm gonna go work in the shop on building my rock sliders.

 

In engines, years ago I've seen them grossly junked up. Before the stronger detergent additives you might see something like a valve cover so full that there is only room for the rockers to move. The logic was that if you then switch to something with the "HD" on the label, (High Detergent), It could free up enough crud to cause more trouble then you would have just running regular oil. Was that in the 70"s?
I gather Tranny fluid now has a ton of detergent. One poster said he washes his hands with it! (before finishing with soap). We all know transmission shop managers stand at the top of the pinnacle of honesty and integrity. Maybe the truth lies in there somewhere. Maybe there was a time when you might be asking for trouble.

Below is a post I saved last year, at the bottom he mentions using Berrymans to clean out an AW4. Maybe something to try before giving up on one. ;

Try again - the AW4 is a 30-40LE with an extra clutch, built by Toyota, designed by Toyota, as used in the Celica, Supra, pickup, RWD van, and some RWD Lexus.

Just as the axles are shipped from Dana, the transmissions are shipped from Toyota - and the Toyota spec applies.

The BA-10 shipped from Peugeot, the AX-4, AX-5, and AX-15 all ship from Toyota (they're derivations of Toyota designs with different monikers - I believe the AX-15 is essentially a Toyota R150 light truck transmission.)

The early T4/T5 transmission (1984-1986 4-150 and V6-173) shipped from BorgWarner, and BorgWarner specs would apply in those cases (fortunately, they're just GL-3 gear oil to protect the bronze synchroniser rings, as in the AX-4/5/15. The BA-10 doesn't have a speck of yellow metal in it, which is why it can use GL-5. I know the FSM sez to use GL-5 in the AX-15 et al - this is one of those very limited cases where the FSM is itself wrong.)

I've heard of a TSB that sez the ATF +4 "Multi-Spec" can be used in the AW4, but reports from the field are mixed at best. Ergo, since Dexron is still available, use Dexron and save yourself the headache.

(TANGENT: Reports from the field on "power-flushing" the AW4 by forcing fresh fluid through it are mixed, but generally negative. If you suspect it's crudded up, the best method found to date is to buy a case of Dexron and 3-4 cans of B-12 "Chemtool" - dump in a can of Chemtool and change the fluid - hot! - in 1,000 miles. Repeat twice. This seems to be easier on the transmission and clutches than powerflushing.)

But, considering nearly every AW4 slushbox I've seen has had "Aisin Seiki" ID plates on it, I feel secure in saying it's a Toyota design as used...
