Mine did it first thing this moring backing out of the driveway.
It was slow to engage into REV, then the TC locked when put into DRIVE.
I popped it into N to get the Jeep to stop, put it back into D and everything was OK.
This was the third time it has happened in the last 10 months.

Dave, not trying to be butthead :oops:

. All I have to say is get used to it unless you have the desire to make a large investment...it will ultimately be worse in the summer and better in the winter (you may even think the problem went away).

I wonder if my extended warranty will cover repairs? I've got ~10K miles left on extended warranty.
Then would the dealership, or whoever can do the repair, be able reproduce the problem and
properly diagnose... :?:

I wish you well. My dealer techs played dumb until the warranty ran out...

Joe mentioned the front pump. I not sure whether you can "prove" that so that the claim could be submitted and reimbursed to the dealer. Start throwing parts at the problem and you'll likely be left with the bill :banghead:

IMHO it is too much risk for a dealer to take this risk on your behalf on a used vehicle that has been discontinued (drivetrain), the model has changed AND is being kept alive by the government that was then bought by a foreign firm for pennies on the dollar...and expect to be reimbursed for a (their perspective) frivolous repair.

Whoah, you LOST :JEEPIN:

Who is your warranty through? Have you taken it in for this and is it documented? If so and it's a Chrysler warranty try it

Be very nice and explain your case. I'm about half way on my 7/70 warranty and have an appointment to take it in on the 21st of the month :jester:

Yes,

, sorry about that. My dealer drove the rig no less than three times to repeat the problem. One time it did it to the mechanic while I was in the Jeep with them :ROTFL:

. I got nothing. Nothing read on their OBD reader therefore NOTHING happened and that was back when Jeep was DCX not USA/FIAT ( http://www.nytimes.com/2009/06/11/busin ... ysler.html )

I wish you well. You know what I will be doing... :5SHOTS:

OK, with the new TC I have not had any engagement problems like I had in the past. Some times it was slow to engage the initial P to R, It has not had that problem since. I did not change the front pump, the front pump valve. I did not change the fluid or filters, just the TC. So alot of you may think it is valves or a bad spin on filter, it may just be your TC. All I did was change the TC and topped off the fluid with 2 quarts.

This subject has been at the top of the list since I joined here back in 06 :mrgreen:

Many moons ago Danoid stated these transmissions were basically very sound but suffer from air leaks :juggle:

Further as I remember it, could be wrong, the TC clutch is normally locked and requires fluid pressure to unlock it. The original front pump, actually the only pump as rear pumps have been gone for years, along with it's cover were one possible source of leaks :SOMBRERO:

What can I say Joe, I am only stating my experience with a new TC. I did not replace any valves and all is fine with TC replacement only. That is interesting that the clutch needs fluid pressure to unlock it, or at least you think

Maybe the clutch has a hard time unlocking with that fluid pressure when the TC is failing?

it's also been attributed to leaking antidrainback valves in the filters.
so if you change both filters it may go away
(or get used to letting it idle in Neutral for 30 secs before you drive)

Joe Romas · **Posted:** Sun Jun 20, 2010 11:07 am

Mine is fine first start of the day :SOMBRERO:

But after it's good and warm the shift to park is real rough and crunches like something, torque converter clutch maybe, is not releasing :shock:

That problem went away with a new TC and a top off of 2 quarts of ATF, no other parts.

Sounds like it is time. Are you still on the original TC or did you get a new one under recall? Not to say much the recall one was the same POS any ways.

Actually those made before November 2005 had a different TC and they were replaced with the same ones those made after November 05 came with. Mine was Made in January 06 so it had the newer of the two and it has not been replaced :shock:

Tomarrow it's going in for a new one and it should be the "euro" one. I suspect an air leak and hopefully the new front cover will cure that.

That's great, your CRD will be that much more better when it is done.

Just to throw in my $0.02. I had the stalling and hesitation problems. I replaced both the TC and pump w/ the Euro versions and the xmission has been rock solid. Multiple shifts right after start-up works perfectly. My thinking was that since I was out of warranty and I was already paying to have the tranny pulled, a new pump didn't add that much to the total cost and I'm confident that the xmission is now bulletproof.

Joe Romas · **Posted:** Wed Jun 23, 2010 7:49 am

Our tractor engines bring out transmission/tc problems not seen in gasoline powered vehicles. It's been mentioned before that our peak torque is developed at a low RPM before the pump is putting out enough pressure/volume. And without that it's just not happy :shock:

With that in mind ANY tiny air leak is going to cause problems. What maybe allowable tolerences for a gasoline engine just won't work right for us. Think about the different seals in the belhousing area where the TC resides and it'seasy to see how air can leak in.... Just like some of our fuel systems :BANANA:
