The Car:
95 LT1 Z28, 4L60e
I've adjusted my shift points multiple times and it has always worked very well. The actual shift comes ~200RPM later than what I program, but that delay is expected and consistent: setting to 5800 brings a shift right around 6000, setting to 6300 brings a shift right around 6500, etc etc.
The New Parts:
I just installed the following in the tranny:
- 2400 stalled torque converter
- Servo from a Corvette
- Shift Kit (RatioTek)
The Problem:
The car now shifts at 7k rpm.
- Was there something I was supposed to change in the ECU after installing a shift kit to keep it shifting properly?
- Is there such thing as a shift kit which not only hardens shifts, but actually delays the shift point them as well?
