Trans All locked up! 05 Renegade 4X4

[trail rated]

Especially with that 42RLE behind the 4.0....

Get one with a 4.7 and 545RFE if you go that route, man.

4.0s are "teh suck", as the interweb nerdz would say.

Yes, especially with the 42RLE. rofl2.gif

If you don't know what trans goes behind the 4.0s in ZJs and WJs than maybe you shouldn't be talking bad about the 4.0 either. Sure the 42RE doesn't have a good track record but mine has 180K on it and the only thing it ever needed was a fluid change every 50K, still shifts smooth too.

And as for the 4.0s, they are not bulletproof, they are bombproof. I'm sure most engines would seize if you drive them without a water pump for 20 miles when it's 95* outside.
Interesting thing is that when I ask technicians for opinions on the 3.7 and 4.7, they tell me that they would personally never own one. Why? One tech said that he has one come in with some type of internal engine problem every week!

What did the techs say about the 4.0? They said that those things usually go 350,000 without as much as a hiccup.

x2, although you mean 42RE, not 42RLE. Two entirely different transmissions.

Some people must like leaks I guess?

All the while... LEAKING!

I still have yet to see any terrible reports about the 3.7L / 4.7L. For an engine to have been in production THIS LONG to have the major issues that people "claim" are wrong with this engine, it would have as terrible as a reputation as Chrysler's 2.7L V6 and Toyota's 3.0L V6. Sorry.

The 4.0s leak because of bad rear main seals, it's $30 and a couple of hours to replace. Some early 4.0s have problems with oil filter adapter gaskets.

4.0Ls leak from more places than that, but it doesn't matter where, they are chronic leakers. That's the whole point. Nothing more.

Nope, those are the only two common leak points in the 4.0.
Any other seal leakes will be just as common as the average vehicle.


To all of you 4.0 haters: The 4.0 isn't just an engine, it's a way of life.

And valve cover gaskets...and water pumps...oil pan gaskets...

Hmm. If it weren't for the POS Dana front axle in ThunderbirdJunkie's KJ making everything greasy, he'd go take a picture of his nice, clean, leak-free 3.7.

Listening to dealer technicians about "internal issues" makes about as much sense as asking your Indian friends if they'd like to join you for a steak. The 4.0 has been out of circulation on the new-car lots (in VOLUME...TJ's don't count, since they typically see less miles than WJs and XJs) for...oooooh....5 years now?

The thing is, ThunderbirdJunkie thinks the 4.0 *****, and don't try to convince him any different. It was a POS when it was the 232, the 258, and the Renix, and 195, and 199. And what's the huge difference between the RE and RLE? And is we incorrect when we change our statement to "The 545RFE is superior to the 42RE"? If so, why did they not use the 42RE behind the 4.7s and Hemis in the Rams?

Just curious

 

[J-Thompson]

The difference is between the TJ and the JK is...weight.

The 3.8 and 4.0 have very similar powerbands ITBJHO.

That doesn't stop the 4.0 from being a sucky, leaky, POS.

if 200# is breaking the bank then the 3.8 really does bring the suck
I wheel with guys who run MODDED TJ unlimiteds and carry "stuff"
easily breaking the 5K# range and none of them ever stall going up hill
I have seen BONE stock JK's stall on the same hill
in order to make it they have to go much faster
sure 4.88's and 35's are a little different than 3.73's and 32's but not much
but hitting a tree at 2 mph VS 20 mph is where it hurts

say what you want but I smell a bad case of "engine envy"
I plan to run my 4.0 until I can change the oil through the tail pipe
then rebuild it and stroker style ,V8 power with I6 weight
can't do that with a 3.8

and and to the "leaky pos"
I have a 7 year old 4.0 that has been wheeled hard for the past 4 years and it does not even have a "wet spot" at the rear main seal
hard wheelin on a 4.0 = leaky main seal
just the name of the game

sorry very very OT

Actually every gasket is a common leak in a 4.0 I-6,sorry but that is true but they do make good low end torque.I've replaced more valve cover gaskets,oil pan gaskets,and oil filter adapter o-rings more then 3.7/4.7 gaskets and almost all the 4.0's have had way less miles then the 4.7's.

yeah but the number of 4.0's out there is scary
and how many of them have over 150K and are still being beat on the trails daily?
no doubt some of them leak
I have heard that one of the main causes is "hot spots" in the 4.0
also the rear main seal does not like high RPM ,for a 4.0 3K is high rpm
who really cares?
the damn thing is a mule and there is no arguing that
leaky and all

Not saying the 4.0 I-6 is a bad engine,just likes to leak is all.I-6's and I-8's have major issues with #1 cylinder being to cold while #6/#8 cylinder being to hot,just the nature of having a long engine.

 

[ThunderbirdJunkie]

Sorry, but if an engine cannot retain its fluids throughout most of its service life, it's got issues. OHV 3.8 included.

But the 3.3/3.8 ITBJHO is a better, more abuseable engine...but time will tell with the Jeep guys...because soccer moms have known it for decades...

 

[JeepJeepster]

wow, ot in a hurry. Hope the dealer takes care of you.

And to those who think the 4.0 isnt bullet proof b/c it leaks are insane. Weve got two 4.0's and I would take them over the 3.7 any day of the week. One has 165k while the other has 95k, neither show any signs of losing power, burning oil, nothing. The 165k one has been leaking oil from the rear main for years but I cant figure out why that matters. It keeps the under body coated nicely so theres zero rust and the oil level never drop, it doesnt leak enough to do that. 42re behind the 165k 4.0 has been trouble free and it has towed more than my kj ever will. The 3.7/42rle will never compare to the 4.0/42re or the 4.0/aw4...

 

[ThunderbirdJunkie]

oil leak=water gets in

water gets in engine=no longer bulletproof

 

[J-Thompson]

oil leak=water gets in

ha ha ha ha
water can get in through an oil leak on an engine?
yeah maybe if the engine is just sitting there in water not running
but if the engine is running it has this little thing called oil pressure
which means that the oil wants out more than the water wants in

maybe the water where you come from is different than the water where I come from

 

[ShafferNY]

Maybe you guys should start a new topic on this with a poll. lol

Personally. I've always been a fan of inline engines, due to their torque and reliability. I loved my 170 I-6 in my '66 Bronco.

Loved the I6, be it slant or straight up...

Well here is the update. Dealer called and said its the transfer case. He said the fluid in it was nasty and it may not be covered under warranty. He will speak to the supervisor thing. He called back a few minutes later and told us his sup said they will proceed as a warranty repair. THANK GOD! They will call back to let us know the extent of the damage and a time frame for repair. If they fix it as warranty they certainly will have my business when I trade up or buy new. If it gets fixed I will also sched a trans flush next month.

Kinda figured(stated in my 1st post in this thread),do you have the 242 select trac t-case(has full time option)? If so bet the shifting mechanism got jammed.

 

[Bikeflyer]

What is the "full time" or "part time" option defined as. I have seen the part-time light on and wondered what this meant? Just curious
