misterp Posted February 1, 2011 Report Share Posted February 1, 2011 (edited) For a Max-effort Radix build: * Converter, 2800-RPM * Billet Output Shaft * Hardened Input Shaft (minimum) or Billet Input Shaft (preferred) * Main Drum Hub Sleeve/Reinforcement Kit & piston * Beast Shell * Hi-Rev release spring kit * Alto Carbonite PowerBand, narrow (minimum) -or- wide one & new drum (optional) * Borg-Warner Dual-Cage 29-element Sprag * Blue Plate Special 3/4 frictions * Kolene full thickness steel plates * Raybestos Forward & Overrun Clutches * Overhaul Kit (gaskets, seals, washers, sealing rings, case bushings, filter, etc) * Vette Servo * Sonnax Superior/Fairbanks Maximum Overdrive servo * EPC Valve * Aluminum accumulator Pistons * Sonnax Drum quick drain valve * Sonnax 3rd accumulator orifice check valve * New AFL valve * Sonnax shift improver kit * TruCool Max Transmission Cooler * Dex-III fluid and LubeGuard Platinum friction modifier * 13-vane pump and .490 boost valve This is assuming you have a 4L65, if you have a 4L60 then you will have to add 5-pinion planetaries; if you have a 4L70 then you can skip the Beast Shell. This is also assuming you have someone that knows what to do with these parts and set-up the transmission build correctly; in my experience I've only met one person and heard of a couple others in the country that are qualified to build a max-performance 4L60. There is much more to making the 4L60 live than just reassembling it to factory specs with improved parts, if you do that you'll just have a dead frictions in just a few months. The secret is all in the setup. All the parts listed will run about $2400-2500; expect labor to build the transmission to be about $550. If you pay someone to remove & reinstall the transmission, that's another $400-500 in labor. MAKE SURE that you deal with a transmission builder that doesn't rip you off - I hate to stereotype, but experience has shown that many "transmission professionals" will charge you for hi-performance parts but on later teardowns you discover it's only got stock internals and you did not receive what you paid for. Follow-up on their references. Mr. P. Edited February 1, 2011 by Mr. P. (see edit history) Quote Link to comment Share on other sites More sharing options...
