The carfax report of my 06 Lerado says the transmission fluid was flushed and serviced about 2.5 yrs ago when it had about 85,000 miles and I think that was the only time the fluid was flushed. Now it has about 110,000 miles. I checked the transmission fluid about 4 months ago and the it appeared to be clear and smelled normal. I am going to let a dealership check the fluid level since the car doesn't come with the dipstick but am concerned they will insist on flushing my system. The car shifts pretty smoothly except sometimes the small delay from N to R/D. Should I really get it flushed?
parox - He'll only have the one filter in his NAG1 trans...
I wouldn't bother flushing it or changing it at this point. Nor would I take it to the dealer to have the level checked, you can buy the dipstick and do it yourself saving a fair chunk of change.
I personally go 40-50k between trans services. Drop pan and change filter(s).
The most expensive components on your Jeep are the engine and transmission. I service strictly by the service manual recommendations for that reason.
You may already know that a service is a partial fluid and filter replacement. A flush can be a full fluid replacement and filter replacement. A flush can also be a cleaning with a chemical. Do not go with a chemical flush as that is harsh. Make sure you communicate very clearly on what type of work the technician will perform before the work is done.
My service is every 30,000 miles which is about 5 years and it includes a complete change of fluids and filters.
When I purchased my vehicle new, the dealer gave me a Mopar Service pamphlet and the 30,000 mile service calls for transmission service. The factory service manual does not call for a service until 60,000 miles but I know that the factory service manual was published before 2005 and is rarely and very poorly updated.
I have seen 60k miles for severe service and 100k miles for standard service. I generally drive me 10' hemi like a stole it I am at 48k miles, wondering if I should do a filter and fluid replacement at 50k or not because of my driving style... Also is it possible to do this service yourself or should I just go to the dealer?
Here is what I have done.
Since I have a drain plug, I drain, measure, replace fluid at 6,250 mile oil change.
Since atf has a high cleansing property its surely overkill. but having a friend that has a tranny shop, his recommendation is
that it is cheap preventative maintenance.
Not knowing service history of mine I did complete fluid, filter, flush at purchase.
I got a 3.7L and just got the tranny serviced at the dealer at 108k miles. Was $30 more to flush than drop the pan and just put in more fluid and a filter. Didn't flush it and the service tech said the fluid looked good for that many miles.
Does anyone on here have the part number for the dipstick? I have a 3.7 with 86k and I dont think the fluid has ever been changed. thinking of changing it out sometime soon.
My understanding is that a trans "flush" is risky and can cause more harm than good, and by flush I mean the type that is done by hooking it up to a machine. I've always done a passive flush, unhook a trans cooler line and replace what I pump out, or simply drain and fill with a new filter. My previous vehicle was a 2500 GMC with an Allison trans so I wasn't about to screw that one up.
"The 2005 JGC is 3,500+lbs without passengers and luggage" . . .
. . . Also without the engine or transmission. The 2005 JGC is just under 4700 lbs without passengers and luggage, but with all the other important stuff, including wheels.
I would also like to see any hard proof stating that WK transmissions require a 30K transmission fluid change. Here is basic info for WK maintenance intervals; http://wkjeeps.com/wk_maintenance.htm#SPARK
I'm sure my transmission is fine. Ive only put 55,000 miles on the Jeep in 6+ years of ownership. At 75k everything works great with schedule B service interval followed. I do not abuse it or neglect it. My front differential bushings are still solid and like new at 75k.
Do not trust the Factory Service manual or reproductions of it on the internet. Simply examine service schedule A and B in the Factory Service manual. Among the inconsistencies you will find that schedule B calls for changing the front and rear axle fluid every 12,000 miles and schedule A calls for changing the front and rear fluids never.
Also, look at the 60,000 mile antifreeze change on schedule A. The type written entry calls for 60 months or 102,000 miles but the X in the column is for 60,000 miles. In addition, the Factory Service manual calls for lubricating the upper knuckle ball stud every 12,000 miles. There is no upper knuckle ball stud to be lubricated in the WK jeeps.
After examining the inconsistencies and errors at some point you have to wonder what is the correct maintenance schedule for this vehicle. I use service schedule B and the mopar service manual I received at the time of my new car purchase. At the conflicts I defer to the lower mileage or time recommendation.
I noticed the owners manual inconsistencies as well in mine. Other error included listing the incorrect bulb p/n's for the tail lights. Shows a 3 bulb tail light assembly and mine is a 2 bulb, show's a bulb for the 3rd high mounted brake but mine is factory LED.
So these are official mopar required service coupons you have here? Oil changes every 3k miles? That is not the recommendation anymore. Hasn't been for a long time. You can drain 7.5 qts of oil every 3k miles if you want to. Seems a bit wasteful.
I would like to see how they "lubricate upper knuckle ball stud" on a non servicable upper ball joint on a wk. You might go get your money back for that. It's not even the proper terminology. This is just what it looks like. Dealer propaganda to bring customers in more often who dont know the difference between upper knuckle ball studs and ball joints.
Yes, 3 months or 3,000 miles for engine oil. The most concerning part of the 4.7L PowerTech Chrysler engine is the small oil passages including the lash adjusters. The small oil passages do not react well to dirty oil. Popular articles on extended oil changes make one big assumption - all engines are the same. They are not.
Mechanics knowledgeable about the 4.7L PowerTech engine will tell you the most important thing with this engine is to keep changing the engine oil.
Still in doubt, google 4.7L engine problems. There are a host of items written mostly on the Dodge Durango which uses the 4.7 engine. Some call it oil sludge others think it is a defective engine.
My local car dealer says the official manufacturer recommendation is *not* to change automatic transmission oil for 3.0 CRD (2006 WH).
Really !? Sounds little a bit odd that you do not have to do regulary automatic transmission oil changes...
Could this be the reason why the http://www.wkjeeps.com/wk_maintenance.htm#TRANS does not say anything about automatic transmission oil and filter types, quantites and scheduling for this model ?
having run repair shops for years, I would NEVER recommend a chemical flush on any trans with any miles on it. chemical flushes are suppost to remove any debris in the trans. the problem is if something gets lodged in one of those small passages your trans is done.
the best bet is to drain the fluid, change the filter (s) and refill.
