TCC Lock?

[jve]

Hello,

I'm trying to get the TCC to lock in 3rd. I'm using the tap up tap down shifting to do this. I've modified the speeds so that it stays in each gear and then I modified the Apply and Release tables so that lower values (20 mph for "apply" for all TPS values and 18 for release for all TPS values). I can see that there is still a good deal of slip going on by logging the input and output shafts as well as TCC Slip. I also modified the the full throttle maps in the same manner.

Can anyone tell me what I'm missing?

Thank you.

Are you just trying to lock it in third for a dyno pull?

OK. I'm obviously new to this Yeah, let's say that I want to dyno this thing. How do I keep it in gear without downshifting at throttle greater than 84%? I can lock the TCC with VCM Controls - on the Trans tab. I can select 3rd great but I still get downshifts at high load. How do you dyno WOT?

Thanks!
