Sct trans firmness adjustment

I know we can adjust shift firmness,is this only for WOT? My 4 to 5 ( if i have that right) shift is to soft,so I want it to shift harder.Its fine on WOT,just to soft of a shift on normal driving.I am just trying to make it to winter then I will be getting a performance trans.The other gear shifts are fine. Thanks for any info.

its the 3-5 shift. The trans doesn't use 4th gear. You can tell your tuner to adjust the firmness of the shift and they will do it in the program. I just had Eric at Innovative Diesel firm up my 3-5 shift...and it made an improvement. You can also get a modded DD solenoid that controls the 3-5. I did the modded DD solenoid and also had firmed up with tuning.

I've bump all my shifts on mine all the way to 25%...but it doesn't ever make a difference for me..it's the same at 0% as it is at 25%... but I still do it everytime I download a tune.

really the trans doesn't use 4th gear,, when I was running stock I swear I counted 5 gears,, does it use 4th stock? and not use 4th gear when it's tuned, if you could give me more info on this I would appreciate it

ok I bumped my 3-5 up to 15% it still seems a bit soft to me,,, it's better though, it seems like it made a difference in down shifting,, a big difference, I also turned my idle up to 775, I like the way it sounds when it's at idle, that also seems to make for quicker take offs, just did a test drive, I might bump the pressure 3-5 up to 25 tomorrow

It'll only use 4th when trans fluid is at a certain temp...which is when its cold. When the trans warms up to a certain temp it stops using 4th gear. That's why there is no option to raise the shift pressure for a 3-4....simply because its not using it. That's why its for the 3-5
