The build date on my CRD is 12/05. Is it safe to say that mine came from the factory with the F37 de-tune? I have the dealership maintenance records (the previous owner always had it servced there) but can't decipher their encoding to determine what recalls were done.

It had 3 recalls, one 8/8/06 with 2790 miles, on the same date as the first entry - I assume it was the date of purchase - and another 6/18/07 with 10,543 miles. The third and final was 8/2/07 at 12,332 miles. The code attached to each in the dealer record is "50CHZ".

Mine has the same build date. If I remember right, the cut off date was Oct '05 so yes, it does have it. One way to tell is if it shifts into OD at 64 mph.

It shifts into OD at 61 according to my GPS, (which I bought because of the speedo being wrong. . .) so that would be 64 on the speedo. Thanks for the info.

No problem. I equate my longevity torque converter to this down powering. I think they screwed up on the engineering, but the short term fix seems to be working.

NO None of the US CRD's came from the factory with the F37 flash!! F37 came out after they stopped producing US version CRD's BUT CRD's from November 05 onward came with a different (older style) torque converter that the pre November 05 units got during the F37 "customer satisfication" action, It's NOT A RECALL The older style TC's they went back to did not have some sort of cushion that was the part that was failing at very low mileage. Mine was built in 1/06 and I bought it in May 06. The first trip to the dealer was in June 06 when they preformed two flashes. One to the BCM for draining the battery and the second changed the shift points and possibly detuned it AND caused it to not communicate with third party scanners and code readers. It was then out of EPA compliance so they created F31 that was a recall to correct that problem When they preformed F31 on my crd they also preformed the offcial version of F37 that changed the shift points again and detuned it (more??)
Your CRD most likely went down the same path as mind did

BVCRD, Remember back when F37 was released we wondered why our post 11/05's were not included and but we later got the detuning flash (shaft) The simple fact is the CRD's torque was too close to the rating of the transmission that was totally updated for 08 MY (and yes I know there were no 08 KJ's)

I do Joe. It's been a while since I addressed that issue, I guess my mind is slipping. Thanks for clearing that up. Now I remember going in, pleading for the F37 so my TC wouldn't explode like others had. Again, sorry for the confusion.

Your too young to have a "senior moment" Just wait till you get to my age, some things get better and some worse

Have you had any egr/fcv valve problems yet? At 22k I've had both replaced. The EGR gave a cell and the FCV stripped it's gears. We towed our 3500 pound camping trailer (one reason I bought it) to the Outter Banks of North Carolina last summer, through the mountains in West Virginia and Pennsylvania, the transmission's constant shifting was very dissappointing but I did get 19 mpg doing it. If I didn't have the 7/70 extended warranty I would get the inmotion tune and a Suncoast when the TC died and dollar wise it would be a wash but that's hind sight
I recently bought the wife a very nice 00 Cherokee Classic, my 4th XJ, and sure wish I had it's ASIN transmission in my CRD. It's a real transmission:lol:

I'm over well over 50 now and things aren't as "sharp" as they used to be. I haven't had any failures since the CAC hose did the weeping thing. Nothing. We pretty much baby this thing, kicking it into neutral when sitting at a stoplight. Trying to keep as much heat out of the TC as posible. To tell you the truth, if I hadn't read all the troubles others on here have had, I'd think it was a pretty good rig. I haven't been off road much with it lately. We have had a dry winter and some areas will be opening up soon. The camping bug is flying around. Might have to head out. Supposed to be in the 70s this week.

So what is the difference between the torque converter in post 11/05 CRD's and pre 11/05 CRD's? I'm out of warranty now so I'm not concerned there about doing the Suncoast, but if I don't have to then I don't want to. I know I need to if I plan on an Inmotion or similar tuning. (which would be nice)

Since I'm the second owner, apart from the dealer service records, I don't have much to go on to determine if it has been "re-flashed" or not. I just seriously don't want this thing to unexpectedly detonate on me.

According to a report here what was shattering in the original pre 11/05's was a part that cushioned or smoothed the operation. Post 11/05's don't have this "feature" This is all "unofficial" information, the problem was never, to my knowledge, released publicly from DC If your TC is still working you don't have that one. They failed in just a few thousand miles

The flash level information can be retrieved by some scanners such as registered versions of VAG-COM and the tech section has the information

I have a 05/05 build date on my jeep. I installed a aux tranny cooler early on cause I knew I'd be towing. I'm at 38K now and have the original TC. I wonder if having the extra cooling helped my TC not go south?:evil:

I don't think heat was the culprit. It couldn't have hurt any, but like Joe said, the vibrations caused metal fatigue and those vanes sheared off inside.

So how is the post-11/05 TC? Is it good for 300+K, or is it also a weak point?

I think the jury is still out, but I feel better about them. Maybe DC used them in some other stuff that has high mileage tests. Durango ???

Does anyone have a part number for post 11/05 Torque Converters?

Aaaa, I think I am getting in on this late and Joe is a great resource but I think he is slightly incorrect here but not to the person that posed the question. The TC issue was identified and the detune was applied at the factory sometime in February of '06 if memory serves and I am sure they continued in manufacture after February '06. Again, if memory serves, they were producted into early June '06. The F37 was applicable to a specific range of transimissions based in the transmission build date, not the vehicle build date, and those ranges were posted on the recall notice. You needed to crawl under the KJ and read the numbers off the transmission to ID if you were in the build range.

Man, it's all coming back to me. I do remember crawling under there way back when. I did go to the stealership in March of 2006 begging, in fact pleading for the reflash and they gave it to me. Back then, there was a new reflash coming out about every 2 weeks.

Dave.

As I remember it the build date of the transmission was for the recall of the filters that didn't have the anti drain back valve in them?? (I don't have that notice)

It's hard to imagine a vehicle with so many "issues"

Here's the first page of the F37 instructions. Note ALL OF THE DATES on the page AND THE TOTAL NUMBER OF INVOLVED VEHICLES.. Mine was built in January of 06 and had the ok TC but did get a flash in June 06 that changed shift points, the one that caused the need for f31, and a official F37 flash later when I had f31 done. I have a copy of the f37 letter sent to customers who got the replacement TC's but it has no usefull information as far as dates go.

It sure would have been nice if the engine group would have talked to the transmission group to begin with so we would have had a engine that would operate at it's potential without killing TC's and transmissions Or maybe a little testing before releasing them to the public I'll bet Tata will do a better job on his products
