Slow TCC ramp up

[x MadMAX DIESEL]

What causes Slow ramp up of the duty cycle? Normally When cruising I will get a ramp up of 14.5>20>28>65.5

But some cases I will literally get 13>14>15>16 etc. all the up to 65.5, and when that happens I get TC slip even when at 65.5 duty cycle.

Doesn't matter who built it so don't even ask that or for a log and then decide not to help after weazeling info. You know who you are :thumb:

Just looking for a simple answer as to what causes slow ramp up. If you want I can post a screen shot of a log if that would help, but only if that is neccessary to diagnose.

stock TCM tune? What converter? Do you know what your builder did with the converter flow valve?

ML TC, Stock TCM tune. I do not know what was done to that.

The weird thing is that I only get funny ramp up after I do a boost launch and run it hard. If I restart the truck after all is fine and normal again


Is there a table that will give it a slow ramp up if something out of the ordinary happens or something like that ?

If it does it after a boosted launch the TCM is inhibiting TCC.

Check out table D5072. I doubt it is your problem, but it might have something to do with it.

I will look at that when I'm on the other computer. Forgot to say though, the TC locks fine when I boost launch it. Only after I let off and slow down is when I start gettin the funny lockup.

I looked at it. I don't really know what I'm looking at though. Like I said it is a stock TCM tune.

Well in a stock TCM there are limiting factors. Josh just posted the table for you to look at heck it out ,if it still dont make sense what you need to do then contact a tuner.

I have no idea how many guys run stock tunes? But since EFI allowed TCM acess i was in like flinn
