Okay I just swaped my computer, and engine out of my 87 Iroc that had a 94 computer etc in it.

Now with my 95 computer im getting a MALF TCC control feedback fault.

Do i need to rewire something? It seems to shift perfect and I beleive the convertor is locking on the highway/

What to do?

Also Im getting a MALF 96 - 4000RPM VSS Circuit Fault (computer is programed for my buddies 3600 stall and I have a 3000 stall) I dont know if that would matter.

Thanks for any info

A '95 and '94 4L60E aren't compatible. The '95 uses an extra solenoid (PWM solenoid) on the valve body, to control lock-up apply. You're computer is "looking" for that solenoid that isn't there..
I can't see a difference in stall throwing a VSS code.

Thanks! I am going to get my old computer back and swap in my tune
