LS4 V8 Engine Swap

[Leon R]

I think the 98+ 5-speed Troopers use an Aisin, don't recall the number.

What does it mean? Did it have a diff for "AWD mode"?

No, they had a traditional part-time 4WD transfer case. Only auto tranny Troopers had the TOD transfer case.

I got an e-mail back from the guys that make the custom engine adapters. It will be a little more expensive than I was thinking.

For an adapter to mate an Isuzu trans to a GM Vortec 5.3 it would be $850 for the first one and $550 for the next 3. I'd also need to send them the whole entire engine and transmission for them to make them.

Yeah I think i'll just ditch my Aisin and go ahead and swap in a 4L60e. After researching you can get a full swap wiring harness with fuses and a reprogrammed ECU for the Vortec 5.3 and 4L60e tranny for arond $750. That's not bad considering it already comes with a programmed ECU, you can get just the harness for around $500. It seems pretty expensive when I know you can just modify the stock harness for dirt cheap, but I like things super clean and simplified so I think it would be a good idea to get one.

I thought I posted this before, but this is another method to add a starter to LS4:
