Possible tranny/tuning problems? I have a 99 TA with a 4l60E. I recently added a VIG 3600 up from a VIG 2800. The car has done this with both converters..
When I am at the track, the car shifts nice and hard from 1-2, then the 2-3 seems to hang on forever.. The car seems to fall out of the power curve before it shifts.. No matter what changes in edit I made, it still shifted at the same spot...
Right now, the car has 3.42's and the shift points are set as follows:
1-2 37 6500
2-3 76 6200
3-4 125 6200
These are the settings from the "Trans Calibrations" tab.
The car was shifting last night at 6500 by the tach and about 88-90mph... WTF am I missing....
ps, TM is deleted, I have a TR 224 cam and rev limit is set at 6800.....

Re: Possible tranny/tuning problems? Might be a tranny line pressure issue. Did you put in a shift kit? Did you up the shift firmness with LS1edit? You might want to post this in the drivetrain section. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: Possible tranny/tuning problems? The transmission does have a "Shift Kit" the tranny was rebuilt and the builder added his own kinda kit.. Line pressure is still at the stock setting.. This was happening before the tranny rebuild when I had the vig 2800 and no shift kit... I will also post in the drivetrain forum
