Default I need a built 4L80E or a rebuild

my trans is really f'd up. I've been having a weird whistling sound coming from the truck ever since I got it back, actually, for the past year plus. I thought it was either in the stereo system or a vacuum leak. NOPE, it was my trans.

it is slipping pretty bad and now that I know what that feels like I can definitely say it has been doing it for a long time. It now will free rev in 3rd gear up to 4000rpm. yikes. No wonder I don't like driving the truck. The power isn't getting to the rear wheels.

Anyway, I need either a rebuild or a new trans. Any suggestions would be appreciated.

Thanks.

I see we have at least 2 sponsors that do transmissions. I'm hoping to avoid downtime because this is my only vehicle. I'm open to suggestions though.

I'm also unsure of the condition of the converter. It's a Yank SC3000 that I installed 20,000 miles ago. I bought it used.

We have the various sponsors selling there trannies and then there's Hughes, Gearstar (if you are wealthy) and others....

I noticed GM performance also sells a couple versions of the 4L85-E...one of them a beefed up "Supermatic"....
