LS to 4l80e flexplate and TC installation help

[johnnunez29]

In case anyone needs this in the future. You do NOT need the pilot spacer to run the 4l80 on an iron block 6.0. Called tci and they confirmed that is only needed if you will be running an older model trans behind the ls. That was a costly mistake. On to the next mission

This describes how to measure very well. The confusing part of this for how it pertains to you is the 6 bolt vs 3 bolt converter. He’s installing a 6 pad converter made for a 6 bolt flexplate. Everything 6 bolt is for using a stock 4l80 6 bolt flexplate that the flexplate has a built in crank spacer. That allows for a shorter pilot on the converter. Most aftermarket converters use a 3 bolt pattern and are designed for a standard dished 3 bolt flexplate - the converter pilot will be longer to accommodate for both the flexplate dish and lack of spacer on the flexplate.

You haven’t posted a pic of your converter showing the pilot length- I’m guessing it’s longer than the converter that Jake has mounted in the transmission in the video. If you have a short pilot on your converter, then the pilot spacer you received with the flexplate will be needed.

If I’ve made this more confusing, then send me a PM.

Thanks again fellas, for all your help. Have another question (of course). I am not sure how the starter should sit. The gear is pretty far from the flexplate. Not sure if that’s normal or I got the wrong starter. Pics are view from the bottom up. Also the starter bolt kit came with 3 bolts. I can only see where to use the 2 long ones

All LS starters aren’t the same. Many 4.8/5.3’s are, but 6.0 are not.

Ok. Are the starter teeth supposed to rest in the flexplate? Or do they not attach at all? This one attaches perfectly but the teeth are no where near the FP

Picked it up cuz of this review. And that’s the starter
