New Customer Satisfaction Recall - F37

Flying J · **Posted:** Thu Dec 07, 2006 10:54 pm

So I figured this would change the shift points to a higher RPM to allow more line pressure in the tranny. I figured that would destroy MPG as it would take the engine further out of its power curve. However it sounds like it going the other way. I'd be really curious to see the impact on MPG from those that get it done.

For those curious about the P0740 which is the gateway to the improved pump:

Re - Farout - having read some of his posts, do take it with a grain of salt. After having his PCM and EGR replaced by a dealership in Ohio, he posted how the tech was quite knowledgeble and that EGR's would continue to fail unless the PCM was replaced as that was the component causing the EGR failures. He posted this several times as others had multiple EGR failures - he posted this duo as a permanent fix... except that several months, the permanent fix went south and he lost another EGR valve. Sounds like a harmless, but somewhat confused individual trying to figure out what is wrong with his vehicle.

P0740 Codes - from reading many, many posts, don't see very many. When my TC grenaded, it was after months of loud metallic jangling at idle in the driveway, but no P0740 code. But because there was no P0740 code, Jeep only replaced the TC - no tranny pump, or new tranny cooler.

The new TC (old design, was replaced last summer) has now started the jangling, and has "stuck" 3 times at intersections now, but has not failed completely. I won't let anyone in my family drive it now because it is unerving when your vehicle won't stop at the intersection and you don't know when to expect it.

This F37 recall will be the 3rd TC on my CRD. So if they don't replace the pump this time, I'm not sure the new one can last if the pump was damaged when all the metal debris clogged the cooler last time.

Ranger1,

About the sticking you refer to. Do you think the lockup clutch is failing to disengage, or do you think the rotor and stator in the converter are actually bound up somehow?

Not sure - I know its not disengaging when its supposed to when coming to a stop - but its intermittent. Last time that happened, the TC grenaded about 10 miles later. You have to hit the brakes hard, sometimes shift to neutral when it happens. Surprised to see it happening again. After all of the flashes and a new TC, this is what reinforces my belief that DC is still bandaiding this situation. Never had a vehicle with this many issues, ever. Other KJ runs flawlessly with the same tranny.

Isn't it a strange coincidence that the TC kit and the pump kit have part numbers that are one digit apart? I asked for a replacement pump, regardless of who is paying. Will have to wait and see if this is workable.

Has it been determined why since there are 11,200 affected units and that seems to be all of them, that after a certain date in December 05 the f37 does not apply :?:

I want the replacement DZL_LOU got - an entire transmission with the redesigned front pump already in it - and probably a nicely upgraded, and correct for the CRD, torque converter inside it as well. I wonder if they will make him return and have his new transmission gutted.

Well for kicks and laughs I went and plugged in my VIN into Jeep.com and their record keeping stinks because they have me listed as incomplete for the F37.
Holy SHIITE, their not getting anywhere near the new tranny, TC and pump with reprogramming the TCM again and reducing my torque even more!
Pass the doughnuts please!

Go back to page 14 of this thread. I have listed the exact parts list available.

Joe Romas - the F37 recalls ALL CRDs - I'm betting it's just a phased roll out of the notification so they can build up their parts to sufficient quantity.

DZL_LOU - "Told you So!"

I bet you don't have the same TQ we are getting, no one knows if that is a good or bad thing...

My CRD is not included in the recall (presumedly, because the fixes are applied) [snip] Ignore the Stupid Ken Tricks. Apparently, it's just not been entered in the Jeep recall database, yet.

As promised, here are the results of the F37 Recall for my truck. First - some background. My truck was built in May 05, had tranny filters replaced at apprx 6k, and have had every flash TSB performed up to 18-023-06 over Thanksgiving which only made the shuddering worse.

The recall procedure took the dealer the entire day. As mentioned before, the TC part number used is CECAF370, with description on the service ticket listed as Converter 21046004. They noted the ECM and TCM flash updates are the current software being used and did not re-flash again.

I've driven the truck 40-45 miles and note the following: It seems to have the same speed/rpm ratio as usual - 60mph/1800 rpm. As noted earlier it will now stay in lock-up down to 50mph before downshifting and feels solid and smooth through the transition. It think before the lowest was 54-55mph with some serious bucking through the downshift. I was surprised during takeoff from stop the lack of vibration with the new TC. I'd driven so many miles I guess it eventually felt normal. Overall, it feels like the truck I drove off the lot, maybe a tick better. I used to experince the worst problem when the outside temp was below 30 - today was 25 and experienced no problems.

I'm going skiing this weekend, which is always a good test for the truck with people and gear and steep inclines on I-70. Hopefully it will continue to perform well. I haven't driven enough miles yet to comment on mpg, but mine has been so terrible I don't think it can get much worse (I struggle to break 20-21mpg in Colorado.)

I dropped my Jeep off this morning and they gave me a print out of the F37 - I'm pretty sure it got this name because it truly is 37 pages long. I have not read it all and will update more later as I can not scan in 37 pages here at work, but at a minumum it states the TQ must be replaced.

It also gives some cheesy test, the noise test, to determine if you get a new pump. If the rattle sound or fault code is present, you get a new pump - otherwise - your stuck with your old crappy one. IF you are lucky and get a pump, then you also get an entire system flush including the transmission cooler for which A/C lines will be removed and A/C system purged - because - you also get a new integral A/C condenser/Transmission Oil Cooler, along with a new main sump filter and oir return filter.

MAJOR DIFFERENCE HERE ON WHAT YOU GET BASED ON SOME STUPID "CAN YOU HEAR A RATTLE SOUND" WHILE STANDING OUTSIDE THE JEEP - TEST.

Make no mistake, this recall will GUT my CRD. Transmission and transfer case will be pulled and put on a bench per the F37. If the pump is replaced, off comes the front grill, radiator support, and out comes the cooler and A/C condensor.

It also states to try to accomodate the customer and give them a loaner car - but since my dealership had not even read the F37, just printed it for me, no one gave me a car.

Oh yeah, they never really had the parts in stock, they lied. As I suspected - they are recall specific and have to be ordered, they will be in tomorrow afternoon for me.

I know some of you are as pleased as punch that DCX is doing something to address this issue.

I can't join you however.... I think this whole thing smells to high heaven. Call me paranoid or whatever, but this whole thing feels like DCX is doing the very least it can get away with to make this issue go away, or at least to get these vehicles past their warranties. He** people aren't even getting equal treatment under the warranty - what treatment they get is based on the subjective opinion of an individual (whose qualifications may be questionable) who performs a dubious test. If this turkey ever gets litigated, I wonder how that fact will play out in the case. It seems to me it just opens DCX up to further liability. You would think that in addressing a recall, DCX would want to leave all vehicles in a known state - not some partially fixed and others completely fixed.

Again I might be paranoid, but automakers have a history of weaseling their way out of issues like this by doing the very least that they think they can get away with. Sometimes there’s litigation and they get caught. But, they do it again - as if the only lesson learned is "Well we got caught this time. Next time we'll have to do a better job of weaseling." Call me crazy, but I suspect that this might be the cheapest band-aid that DCX thinks it can apply to get them out from under any further liability. I'm skeptical if this is truly the correct approach to actually "fix it right".

I think I’m going to hang out for a while before I do anything – just to see how this whole thing pans out. Right now I can’t say that I’m optimistic.

Mine is not included in the recall, and is one of the last "200". If I am not wrong, and will check again, mine shifts into 4th at about 35-40 (light throttle) and the TC locks up at 53, and shifts into 5th at 63. It will down shift into 4th at about 55,and unlock the TC at about 45-50. This is indicated speed on the speedometer. With the OD turned off, the shift pattern is completely different, the TC locks near 40. I can recheck if necessary.

So you did not get the pump and cooler replaced and it all runs fine. Mine has the same history as yours in that I've hit every reflash and filter TSB the day they hit the internet and it sounds like you have confirmed that my last reflash (18-023-06) IS the latest. Thanks for the update and please correct me if I'm wrong.

It works, thanks for scanning all that in. It shows 36 pages so for those that might get confused, the 37th page is the cover page/notification letter that customers will get that can be viewed at the jeep.com recall website.

My CRD is not included in the recall (presumedly, because the fixes are applied) and this is definitely not what it does. The last OD gear doesn't engage until it hits almost 65mph/2000rpms.

Semi related -- The dealer (re)did the F31 flash and for a couple days it wouldn't shift to the last OD gear until it got to 2200 RPMs -- almost 70. Now its back to "normal".

I've always noticed how much grunting and creaking there is when shifting through P/R/N/D, and how long it takes. I just thought it was normal for a truck-like transmission. Perhaps I'll complain the next time it is at the dealer.

Another case of inequity in this whole thing - if he paid the same thing as everybody else did for the same vehicle, shouldn't he get the same vehicle that everybody else did?

I don't know but my vehicle doesn't wait until 65 mph to hit 5th/OD. My vehicles goes into 5th/OD at 58 mph. I wouldn't want it to have to get to 65 mph before it gets to 5th/OD. Wonder if I only drove rural roads and highways where the speed limit was 55 mph - you may never get the use of OD. That would suck and I would say that you weren't getting the same vehicle that everybody else was even though you paid for the same vehicle.

I hope so, time will tell. I checked this morning and still not there. I'm very leary of the subjective method on the pump, hopefully the "hearing test" will be eliminated and all get the pump. Does anyone know if the 53 mph shutter throws a code their looking for without setting CEL and if so how long it remains stored?

Boy I feel stupid for my last post, it look like mine is included in the recall, after reading the F37 recall. oops...

Has anyone gotten a letter on this? I still am confused at to whether this is an actual recall, or just a TSB.
