Turn off adaptive transmission process!

[Racket]

I hope I'm not stating the obvious but if you have a custom tune you'd have to uninstall it before Forscan mods.

As for the concern about long term issues without the adaptive and the effect on the transmission I can't imagine the adaptive 'feature' was part of the initial mechanical design but who knows when that was introduced.

A couple of tuners offer the 'soft shift' feature and now I wonder if that+adaptive could have been introducing some odd behaviors for some of us - I can't say I have any problems but if it will further refine the trans performance I'm considering turning mine off. I've already got the @TORQUERULES shift strategy on my Unleashed tune. Guess I need to update my Forscan then.

Before driving 650 miles (round trip of 1350 miles in 4 days, but all mileage was accrued in 2 segments in Day 1 and Day 4). I decided to clear and turn off adaptive learning as my transmission was shifting erratically and sometimes hard shifting. I opened Forscan and Cleared Transmission Adaptive Tables, and then Halted Transmission Adaptive Learning. These are the the 2nd and 3rd entries listed below.

I did this 3 days before the actual trip. Immediately after making these changes I drove the truck 20 miles. The transmission had much harder shifts (both upshifts and down shifts), esp below 5th gear. By the time the transmission was warmed up things settled down a bit.

Drove the same distance over the next 2 days and the shifts got progressively better. The improvement continued until the transmission was shifting very smoothly.

I drove the truck this way on the trip and had no issues at all. Things went very smooth.

Now the questions

1. Did I really turn off Adaptive learning by setting Option 3 above to Yes?
2. If so, why did the transmission smooth out over the days prior to the trip?
3. What is the difference between Stop Use of Transmission Adaptive, and Halt Transmission Adaptive Learning?

I like the way my transmission is behaving right now, but exactly what did I do from a technical perspective?

I was going to ask the same question, why would it get better if it was turned off.
Maybe the "option" isnt really an option?

Just my guess that:
"'Halt" could mean "use the tables you already have, don't make any more adjustments for just for this session."
"Stop" may mean, "don't us ANY adapt tables, revert back to defaults for all instances."

Maybe those values are reset with key cycles, so it went back to 'Resume".
You could check with Forscan to see if the values you set are still in effect.

Hey gentlemen. First time poster on this forum. I'm experiencing the transmission issue with my 2019 Ranger Lariat.

The shifts are REALLY bad at this point. Harsh engagement, stalling, searching for gear, gear slip. I'm pissed because the truck is 2000 miles outside of the 60,000 mile warranty. Unbelievable! Ford customer care basically said yeah you're SOL. Dealership claims it needs a rebuild/replacement. From what I've read so far, the issue is prevalent in a lot of vehicles.


My question is, based on the little information above, do you guys think that the repair is beyond what I can do with the Forscan tool?

I had the vehicle into the dealership for routine maintenance(oil change and tire rotation) at the 57,100 mile mark. No transmission issue was occurring prior(or at least I didn't notice it). Odd shifts started happening a thousand miles or so after the dealership maintenance. I let it go for a few weeks and next thing you know, I'm over the warranty mileage and the trans is in full deterioration mode. Unacceptable. I'm beyond angry and unfortunately, I suspect the dealership did something that started the issue(no evidence of this), but c'mon man. The trans was working fine until it wasn't coincidentally right around the warranty period. Not to mention, I was in a dispute with the dealership about a previous service experience.

Take it in and have them look at it. There are known issues with the transmission, so they may make an exception about 2K over warranty. It's happened before.

When they fail, they fail fast and hard.

It will cost very little to reset the tables using Forscan, but there is no guarantee this will fix your issue. You'll be out the cost($35) of a OBDII adapter. I use this one and have had very good luck with it.

My transmission is much better since I cleared/reset the tables.

I have 19K miles on my truck and will be changing the fluid in the very near future when I install the PPE Deep pan. I also spent the $$ for an extended warranty to 100K miles or 2030, which ever comes first. I have never felt the need to buy these warranties before. But the risk of large $$ failures on the Ranger forced me to either unload the Ranger now or purchase the warranty.

I will not be purchasing another Ford product until I see a remarkable improvement in quality.

Best of luck to you.

 

[Nshoe2062]

I appreciate the responses guys. Yea, I had it at the dealership. Ford is not helping me out. They are setting a hard line which is bullsh**. I

 

[Dr_Strangelove]

@Nshoe2062 - Are you the original purchaser of the truck? Did you use the word "goodwill" when asking for help with the situation?

That is how most manufacturers internally refer to this phenomenon of helping people out of warranty - "customer goodwill".

It might be worth your time reaching out to Ford corporate one more time (to speak with a different person, you never know man,) and specifically mention you are seeking goodwill from the company as the original owner of the vehicle (assuming this is so...)

I have heard, anecdotally, of random companies helping second owners as well, but it is usually important to be the original purchaser in these goodwill situations..

Goodwill is usually not 100% of the cost, usually something like 50% or 25%... but better than 0%

Good luck man.

 

[Nshoe2062]

Thank you Dr_Strangelove. Yes, I am the original purchaser of the vehicle. I will reach out again and see if they will assist in goodwill.

 

[Dr_Strangelove]

@Nshoe2062 - you're welcome. I have no personal experience with this - it is just something I have seen a couple of times on this forum and have witnessed many times in my lifetime with other brands. There's a chance that only your dealership has this negotiating power - but if they are unwilling to help I would personally throw the Hail Mary of putting on my sweetest voice and calling myself.

My 2021 is doing a hard 3-skip-to-5 shift under moderate acceleration, but under light or hard acceleration it goes3-4-5 smoothly. Also, when cruising on lever roads at ~35mph 8th gear she'll get jerky as it tries to coast with the trans. staying in direct drive. It will do this at ~50-55mph in 9th sometimes, too.
The service writer fold me to disconnect the battery for 15 minutes, then reconnect and take it for a normal drive of 25 miles. His thinking is the fuzzy logic picked up a fault somewhere. I still made an appointment to have it looked at.
regardless to start a paper trail. 29 months and 50,545 mi. I have a 10yr/150k extended warranty and nothing would make me happier than to never use it.

Have you noticed any increase in fuel economy? I halted mine a few weeks ago and I've been seeing 19.3mpg instead of the old 17.5-18mpg. Shifts better as well albiet using all 10 gears.

 

[TJC]

I travelled last week via interstate 1300 miles at 70mph and averaged 25 mpg. And it was windy going up.

Put it in tow mode. No skipping gears, no shifting to OD at 35mph, no 'hunting' for gears. FYI, 7 is 1:1, 8 - 10 are OD gears.
