98 GS soon to be a GSX clone

[kushfabreakfast]

Hello fellaz, I just purchased my second Regal GS, and since I didn't mod my first one I plan on goin balls deep into this one. Anywho I bought the car knowing it needed a trans, but the price was one I couldn't refuse. I have a pretty good starting point. Super clean interior for a 98, only 122K on odometer, and a slew of new parts. Even already has a K&N cold air intake. Needless to say I'm on the hunt for my tranny first so any help would be greatly appreciated. Doesn't have to be low miles since I plan on rebuilding my original. Just wanna know the mileage and get a fair price. Also any modification ideas would be greatly appreciated. P.S what should I do before going to a smaller pulley on the SC?

Welcome! Any pictures of the cars?

 

No help here on a trans source, however this is a good link for deciding what pulley you should safely run.

I would say pulley should be one of the later things to do. It's best to get all maintenance up to date(what good are mods if the car's running poorly!), and then most importantly..scan scan scan for the engine vitals like KR(knock retard), etc. I was planning a pulley drop on my Regal, but when I scanned the car with just an open cone intake I was seeing around 4-6* of KR. Too much to really feel *truly* safe to do any drop from the 3.8".
