Sponsors please help asap. Please PM me your best price shipped to 67601 on a built 4l60e, 4l65e, or 4l80e to handle around the 700-850rwhp range. I have a forged 402ci lq9 with 550 rwhp as it is N/A but eventually going to throw a 150 or 200 shot at it maybe next year. I would like to be shifting in the 6800-7200rpm range and I currenlty have a vig 4k stall. I need a trans very soon. Money is tight but I need the car going and I want the trans to last. Thank you for your time.

Me n' you are in the same boat bro. I'm drifting around Perfomabuilt's web page right now. (Sponsor of this part of LS1 tech.)

Considering you want to be in the 850 RWHP range, I would look at the Stage III 4L80E builds on our site.
A Stage II would be fine for current power levels, but with your planned upgrades the Stage III or a hybrid between the Stage II and III would be what I would suggest.

With the power you are talking about an 80 is your best option hands down. Vince

not going with a 80e...my car is a 98 and the 98pcm and wiring harness cannot control a 80e electronically. Going with a 4l60e just not sure who i will buy one from or who i could send mine off to to get rebuilt. Currently it is a 650hp built 4l60e using a probuilt rebuild kit, but reverse is gone now.

A 98 PCM can control a 4L80E easily. A segment swap is no longer necessary.

If I understand it you run the adaptor wiring harness and make a small wiring change and a relay? Do I have that correct?

If your stock harness will reach an adapter harness isn't even necessary.

Isn't one need for the 2nd VSS connection?

Not if running a 4L60 tune.
