I’ve heard bad things that’s why I asked lol. What about jasper?

I've heard of them and they do a lot of business across the country. Maybe make a separate post to get the guys opinions that have used them. I think that they used to supply Discount Auto Parts engines and heads in the 1990s and we would buy their heads as cores to port and polish them, we magnafluxed a few in the beginning and they checked out alright. That was a long time ago though. How about a GM Goodwrench engine with a warranty?

Jasper - the king of garbage rebuilds LOL

Popular doesn't mean good. Got 2 bad engines in a row from them. They're also super finicky about their warranty. It exists, but they'll pull anything and everything out of their pocket to deny warranty.

Yes but I believe it just changes the shift points in my model

Yep

It lights up a little yellow trailer light on the dash. It raises shift points, increases shift firmness, locks up the t/c faster, and will allow the trans to freewheel on the sprag when you let off the gas in I think 2nd or third gear. Don't remember which
