Hope this helps.
Thanks and yes this now i can show the wife because she cant tell any diff lol.
Mine after the flashes only down shifts to 3rd and stays there till it i stop and then after 3 seconds it will go into 1st. If they cant get this back to shifting like i did then after the 3 visits i will file on the lemon law. I really like the cherokee but not after the flashes. I just called jeep and they said if the next relearning try doesnt work they will get case management to get involved while the dealer still has it and if they can fix it then we can go from there. I may wait till the 2016 come out as there suppose to have direct injection into the heads which means more hp and there working on a twin turbo for the 3.2 motor but that looks like a 2017/2018 thing. WE SHALL SEE AND ILL KEEP YOU POSTED.

@jim383 - The following is a link to a post by someone that has had luck with R01. Thought you might be interested in his comments about getting on it hard.

Ive been there done that on launching hard going in and out off passing gears and pulling the TCM FUSE and it didnt do nothing and in spots mode the flashes did changed the shifting a little bit and the down shifting is still the same as auto mode. Case Management will take over if this next learning session dont work. If they change the tranny and that dont help i told jeep i will go the lemon law route.

Re: 6 Flashes and 1 RO1 Done 3/26/15.

Well they did a relearning all over and checked for code and after all the relearn it still did the same thing so they called starscan and they told them to order a new tranny valve body and see if that sloves the down shifting problem. The valve body is a special order and its on back order lol. Ill keep in touch and report after they install the valve body.

Probably isn't going to help. These trannys are operated by the electronics and the shift maps dictate what the trans is supposed to be doing at any given time. RO1 deleted the downshift to 2nd at low speed and a 'valve body' isn't going to get that ability back. Good luck with that.

The service manger and i had a long talk and i told him the same thing and he agreed as stranger things have happened lol. The mechanic also agreed but i think they feel they have to do something to get me off there back lol.

Re: 6 Flashes and 1 RO1 Done 3/26/15.

Hey all,

My g/f took her 2015 Cherokee Trailhawk in on May 7 to have the re-programming done. After we sat at the dealer for 4 hours, they told us it wasn't taking the flash upgrade. They were going to have to get a transmission to replace hers. The TH only has 5000 miles on it!!!! They told us it would be 3 or 4 days. We got a call on May 20 from the service guy and he said they hadn't been able to get a transmission in yet and it would probably be after June 1st!!! In the meantime, she was planning to take her Cherokee on a driving vacation with her daughter. The rental she was put in is a Dodge Avenger that is about 2 years old with over 43000 miles on it. She is fit to be tied and wants another rental similar to her Cherokee. She is supposed to leave on the 27th, but she still hasn't heard back from the service guy about the rental upgrade. Anyone got any suggestions to help her get this squared away before Tuesday? If they had told her this "might" cause the tranny to need replacing, she would have driven out of there and brought it back after her vacation when timing wasn't so critical. The service guy was supposed to call her back after talking to the service manager yesterday, but he never did call back and they are both off today. Now it's a waiting game to see if they come through before Tuesday.

Thanks,

Griff

Well after talking to the mechanic he didnt think the valve body would do anything and that they were just doing something to please me lol. He has a 15 with no tranny troubles so i talked to the owner and sales manager if i could drive a late build 15 to see how it shifited and there was a big diff so i said lets drive a limited front wheel dive instead of the 4x4 and the drive was even better. The down shifting went to 2nd gear instead of 3rd and when you stopped it went into 1st gear so i was happy and traded mine in on a 15 limited loaded with the stuff i wanted and the kicker is the jeep is 479 lbs lighter than my 14 trail hawk was. Heres the diff as my 14 trail hawk weight was 4250 lbs and the 2wh drive limited was 3731 lbs. The only thing i dont like is the ( STOP AND GO THING ) so ill leave it off. Being 479 lbs lighter i do notice the performance diff and also the mpg is higher as i had them fill up with 89 octane. The jeep i bought was built 4/23/15 and i got it for -200 below invoice and 3500 from chrysler and the dealer. Window was 36,410 and invoice was 35,127 as you can see theres not much mark up in the cherokees. The 4x4 was a 2000+ option which i didnt want anyway as it saved me 519 lbs and another 50 lbs with no trailer tow but i did get the spare tire. There was no cheery color at all with the V6 motor so i got barb brilliant black as that would of been her next choice. I do miss the transfer case for the sports mode.
