4L80E Rebuild Recommendation

[MtBraun]

Looking for ideas on a rebuild shop for a high HP application 4l80e. Targeting 700hp. I have spoken to Jakes Transmisssions. Had a good conversation but wondering if anyone has experience with them, or other builders out there. Thanks.

I have bought lots of stuff from Jake. His stuff it top shelf quality.

Extreme Automatics is another good place to deal with.

In all honesty, 700hp is nothing to a 4L80. Use Jakes calibration kit, pay attention to the clearances, it will live a long time at that power level.
