S1M Tranny Tune..I LIKE This Tune..Anyone Else?

[fairhaven]

After trying ALL the different tranny tunes I ended up going back to the one that came with the Mini Maxx which is the S1M. For most of my driving (county roads with 45-50mph speed limits) I really like the shift points and tc locks. I usually run the truck up to about 55-56mph and 5th TC kicks in. Then I can drive at 50mph and it stays locked in 5th. And if I'm on a 45mph road in 4th with the tc engaged the excelleration is really nice. I tow my 33' travel trailer on the mild setting with the tow mode engaged and this also works real nice. Most of my driving is on the hot setting.

doesn't work for me, but there are six of them for a reason!

I will say that if I'm on a 45mph road, I'm unlocked in 5th and acceleration is really nice

S2L for this driver.

S2L for me too. TC locks in 5th at 45 mph.

well Capt.
when i'm easy on the throttle it starts dropping gears around 1600rpm or less,,on my truck,,'till i get to third..then about 1950+ for the jump to 4th...
which will be around 35+mph..
for me..
everyone is a little different of course..
then around 45mph i will get to 5th..thats if i continue accelerating...if i just put-put along i can get to 5th gear around 40+mph as long as i am on level ground..otherwise;
say if i going up hill;
it will hang on in 4th a little longer...all depending on my load at the time.
hope this helps...

I'll pound on the throttle on my way to work this morning and pay attention to rpm's and speed.

Ditto....S1M works great for me. The tranny is nice and smooth and I like the lock-up in 4th. Around town, I'm at 45MPH or less, so I like being locked in 4th. Then when I'm on the road 4th and 5th with lock-up is nice

alot of my driving is also on country/gravel roads at 45-50 mph

when I had the S1M loaded , it seems like the trans was always hunting back and forth between 4th and 5th.....very irritating and probably not good for the machinery

loaded the S1L and like it a little better , but still have the same issue at times

will probably try one of the S2 s when I get the time

Try the S2L.....i have alot of the same driving and IMO the S2L is less frustrating

I usually run the S1L but have been running the S2L for the last 2 tanks and can't wait to change it back. The S2L runs higher trans temps because it's always slipping than the S1 trans tunes.
