Default LS swap issues
I just finished completing a LS swap from a 2001 Chevy Tahoe into a 1972 Pontiac Venture. I am having a issue with the 4l60e not shifting like it should. Once it shifts out of 1st it doesn't downshift anymore or shift into 4th, it also doesn't **** unail 5000-rpms. I have a code for shift solenoid 1 and 2 and low alternator voltage? I tested my alternator and it tested fine. Could the low Voltage code be effecting my pcm and the shift points?

LOL.

Wouldn't you think the shift solenoid codes have more to do with it not shifting properly than the alternator voltage code?

I had my transmission check out by a local shop and they told me my SS where fine. The code for the SS could be from the pcm not getting the right amount of voltage?

It could be from the transmission not getting any voltage.
