Default Transmission reset procedure.

With a light foot the trans is shifting at what seems like very late points. Heavier foot equals even later points.

I will observe & get them posted but for now
~2000 or more,
then as late as 2700 or more,
than ~2000 for the last 2.

I am planning a trip in 2 week's & and my mechanic friend will reset it for me at any time w/ the Dodge tool.

My motivation is to get the best fuel economy.
While many say keeping the load under 50% is what to watch, I find the GPH (Torque & OC.Tech both are identical in this.) belies this advice and leads me to believe early shifting is best.

Default Re: Transmission reset procedure. Necessary?

Does your situation fall within any of the mentioned triggers for adaptation being necessary? Were any transmission related parts replaced?

You may have other issues affecting your transmission operation. Adaptation may not accomplish what you are seeking.

The trans will adapt on its own. You can perform the procedure without a scanner. The engine must be left on for 10 minutes after to ensure the values are stored.

It is working.
Reset it 2 days ago. I found the 405 from the 5 to 101 best, a continuous slope.

The down shifts are done 1st. This is the easiest.
Just keep nudging the shifter left then right & you notice an RPM blip when it downshifts

The ups are harder. But same nudging. Just keep at 1500 on a slight slope. It takes a long time. Many honks from LA pee brains even w/ flashers and signals being used w/o flashers.
Breakdown lane needed at times.

I wait 10 minutes after my last 1500 rpm run to shut off.

MWD says it learns 24/7 .

Edit if it does do this continuously then wait the 10 minutes too. If you have a good run in short time.
If it is shifting where you want then it is no matter.

I'm still a bit fuzzy on how you did it.

The procedure that I recall was that the DRBIII would be connected and monitored by a second person during a kinda strict teach in process. It sounds like you reset the TCM and then just used a basic set routine without a second person monitoring anything.

If that is the case, it sounds much easier than what I recall being described.

Ah. I noticed the Alldata sheet. I presume you followed that.

It goes something like this:

Engine off turn key to second detent... dash light will be on

Depress accelerator to floor and wait 1 minute... hold it down.

Turn key off and then release accelerator... wait 10 minutes.

Go drive and have fun.

I don't think that works on the sprinter (i have tried it). Using a compatible scanner to reset adaptations to defaults did create changes for me.

I'm not taking your bait: but I have 2 sprinter and it works equally well on both.
