I have a 94 Camaro A4 with 3600 stall and 4.10's . I adjusted shift times, shift points, and RPM thersholds but the 2-3 shift still wants to hit the rev limiter. What am I doing wrong or is the tranny on its way out?

The 2-3 shift is at about 60+ mph even thu it was set at 47 trying to stay away from rev limiter

 

try lowering your shift rpm point along with your mph and see if that helps.

 

What exactly is the upshift speed threshold in the consants and how does it affect shifts?
What is the downshift speed threshold?

 

Will I'm getting ready to go to the track and I would like to get this figured out before I go.

 

Hot kickdown mode shift speed threshold needs to look like this:

1-2: 1
2-3: 58
3-4: 98
2-1: 0
3-2: 57
4-3: 97

Hot RPM kickdown points:

(Set to the desired shift points for the respective gears as you like. Here's an example for what worked best for me on stock motor)
5800
5700
5700

The gear ratio in the tools/speed calibration section must be right on or you will continually hit off the rev limiter. Set the rev limiter in the constants table to around 6300. Also set the VSS disable in the constants to 3800 or even 4000 if you continue to have problems.

 

I had the vss disable at 4000, then I tried 4500.

I set the rpm threshold to
5500
5100
5500

I had to use 5100 for the 2-3 shift in order to make it shift at about 5600.

Just got back from the track and ran a 12.10 at 110 mph.
