I have a well known ls1 tech sponsor tranny in my car. I spoke with them today they seem to think it might be a issue in the tune but i'm not so sure since its been fine till now. I am trying to get some ideas of what to try.
Heres my problem. WOT 1-2 shifts sometimes happen and sometimes the car wont shift at all. When it does decide to shift the car hesitates to shift for a second or 2. Currently the car will NOT shift 2-3 at wot....just sits on the limiter. When making a pull everything feels solid it just wont shift at wot. The car shifts fine at part throttle & all the gears are present. 4th gear overdrive and lockup are working great on the highway.
Heres what i've done. I've drained the fluid and changed the fluid/filter. There was nothing in the pan & and the fluid looked fine. I have HP tuners. I've lowered my wot shift rpm table from 6800 down to 5900 and it still wont make a wot shift that low on the 2-3. It's been in the car maybe ~4 months. Any help would be appreciated
Oh and also when I lean on the car its always in 3 or D
The first log is a trans log of it not shifting 1/2
2nd is a wot pull where it hesitated but did shift
3rd is the tune
Any help would be appreciated!
