Trans not following tune
So I'm using a CSP based tune. I have doubled checked to make sure I am on the right tune. I am running on tune #4. I have modified the 3-4 shift point and in the base tune I have modified the TCC for 3rd lock. For some reason it's not following my tune, it still shifts whenever it wants and it's not locking up in third like I want. I attached two logs and the tune. Any ideas?

Do you have a custom valve body or kit in it because I do not believe the stock assembly is capable of 3rd gear TC Lock?

Stock transmission, but am pretty darn sure it will lock in 3rd as I can tell when it does in T/H mode and can get it to do it in regular mode also before it hits 4th if I'm careful. Even if we forget about the TCC, why is it shifting to 4th so soon? In the tune I have it not to shift till TOS reach 2100 @ 30% throttle and 2000 @ 20% throttle. I'm holding just slightly higher than 30% throttle and its shifting into fourth around ~1750ish I believe.Originally Posted by Move'n Up
Now 2nd gear I'm not so sure about. I've read many say it will not, but when I have logged the truck and while in second gear, TP% same, TOS and MPH gradually climb, you can see the rpm drop and then start climbing again while everything else is consistent. That makes me think the TCC will lock in 2nd on stock VB. I'm still unsure though. I think you can see it in these logs actually.
Correct, I'm thinking about 2nd gear lockup in a stock trans which isn't possible . Sorry my bad :-D
3rd will lock if O/D is turned off in certain situations.
TOS is a key item to factor in so your on the right track.
I'm at the office so I can't see your tune to provide any feedback

See if these help.
Did you increase pressure?

No, the only thing I adjusted was the TOS vs throttle. I'm just focusing on the 3-4 shift right now and getting 3 to lock TCC sooner.
thats what I figured but I just wanted to double check and make sure that your tb is closing quick enough and not causing a guessing game.

I've gone back through everything and can't figure out why its shifting to 4 so soon....
Anyone got any ideas? Anything else I could post to help?
