Re: 1972 K20 LQ4/4L80E Swap
I'm having some issues with a hard shift from 1st to 2nd in the 4L80 trans, not sure what's up with that and not familiar enough with PCM manipulation of shift points or line pressure change (if that's even possible with the PCM) so I haven't driven it much because I'm worried about breaking something. Hoping I can get it to the guy that rebuilt the trans this weekend to have a look... Here's the cost, probably missing some miscellaneous stuff still, for my conversion including rebuilding the trans.
